Quick links:

What Is the Hiearcool Waterproof Pouch 4-Pack?

This is a set of four universal waterproof phone bags, all in black, each with a detachable, adjustable lanyard (13.8 to 21 inches). The pouches are large enough for most modern smartphones, including big models like iPhone 14 Pro Max and many Samsung Galaxy devices, up to 8.3 inches in length. They are rated IPX8, which is the top tier of water ingress protection, and the listing states waterproofing up to 100 feet (30 meters) under specific test conditions.

Key features at a glance

  • IPX8 waterproof rating up to 100 ft / 30 m (manufacturer’s specification)
  • Universal sizing up to 8.3 inches (fits large iPhones and many Samsung models)
  • 4-pack set for family or multi-device use (all black)
  • Detachable, adjustable lanyard (13.8–21 inches) for hands-free carrying
  • Clear windows for screen visibility and shooting photos/videos
  • Designed for travel, beach, cruise, and general water activities
  • Can also store small items (cards, cash, keys) you want to protect from water

Who It’s For

  • Families headed to a cruise, beach, or water park who want affordable protection for multiple phones
  • Travelers who want a simple, packable water-safe pouch without committing to a bulky, dedicated waterproof phone case
  • Outdoor lovers: kayaking, paddleboarding, snorkeling, camping in rainy conditions, festivals
  • Anyone who needs to keep essentials (phone, ID, cash) dry in rainstorms or splashy environments

Who It’s Not For

  • Divers or underwater content creators who need professional-grade housings and precise camera access
  • People expecting a drop-proof or ruggedized case—this is a water barrier, not a shockproof shell
  • Users who need perfect touchscreen responsiveness while fully submerged (no pouch can guarantee that)

Design, Build, and Fit

Material and construction
The Hiearcool pouch uses a flexible, clear plastic window material suitable for touchscreen use. It’s typical of universal pouches: supple enough to press, swipe, and tap; rigid enough to form a seal when closed correctly; transparent to maintain visibility for the camera and screen. The closure typically involves a multi-seal system, often with locking sliders or clamps—always read the included instructions and follow them strictly.

The seams appear heat-welded along the perimeter, which is standard for IP-rated bags. This technique minimizes the chance of pinhole leaks. The lanyard connects to the pouch via a small loop or ring built into the frame—simple and functional for casual travel use.

Size and compatibility
The stated compatibility is up to 8.3 inches, covering most big phones:

  • Apple: iPhone 14 Pro Max, and most other large iPhone models of similar size
  • Samsung: Many Galaxy devices, including Ultra models in recent generations
  • Others: Most Android devices with similar dimensions

Thick rugged cases can complicate fit, as can large camera bump rings or add-on grips. If you use a bulky case, you may need to remove it before inserting your phone into the pouch. Also, if your phone has protruding camera lenses, make sure the lens area sits flat against the window for the clearest photos.

The included lanyard
The detachable lanyard adjusts from about 13.8 to 21 inches. That range lets you wear it higher on your chest (good for water parks) or a bit lower (comfortable for strolling piers and promenades on a cruise). It’s a welcome convenience for hands-free carrying, and it helps keep your phone secure so it’s not left behind on a lounge chair.

Waterproofing and IPX8: What It Really Means

IPX8 is the highest rating for water ingress protection. Unlike IP67/IP68 on smartphones, which specify dust and water at known depths and durations, IPX8 is “beyond 1 meter, under conditions specified by the manufacturer.” Hiearcool lists waterproofing up to 100 feet (30 meters). A few things to keep in mind:

  • Lab conditions vs. real life: Actual water pressure, movement, and duration underwater can vary. Vigorous water activities (surf, dives, jumps, slides) exert more dynamic pressure than a static test.
  • Always test before use: Perform a “tissue test” (details below) with each pouch before your first outing, and periodically thereafter. It’s simple insurance.
  • Submersion time matters: Even with a high rating, continuous submersion for long periods increases risk. Use common sense; treat this as a protective layer, not a license for deep-water adventures.
  • Not a floating case: Unless a pouch is explicitly marketed as floating, you should not assume it will float with a heavy phone inside. Plan accordingly. If you need buoyancy, add a floating wrist strap or buoy.

Using the Touchscreen and Cameras

Touchscreen control
Most universal pouches allow standard tapping and swiping. Responsiveness can vary based on:

  • Water on the screen: Screen + water + plastic film equals inconsistent touch recognition. Wipe away moisture when possible.
  • Submerged use: Capacitive touchscreens often struggle underwater. Use hardware buttons (like volume) as a shutter for photos.
  • Screen protectors: Stacked layers (glass protector + pouch film) may reduce sensitivity. Increase touch sensitivity in settings if your phone supports it.

Biometrics and unlocking

  • Face ID: Often works through the clear film, but direct sunlight, glare, or fogging can interfere. Be ready to use your passcode.
  • Fingerprint sensors: Most in-screen fingerprint sensors (especially ultrasonic types) will not work reliably through pouch film. Expect to unlock via PIN or pattern.

Camera clarity
Clear windows are designed for photography, but you’ll get the best results if:

  • You wipe the window clean and remove trapped air or bubbles around the camera area
  • You avoid direct glare angles and harsh reflections
  • You tap-to-focus and adjust exposure before sealing the pouch (or use volume-button shutter)
  • You rinse the pouch after saltwater to prevent film haze over time

Everyday Use on a Cruise, Beach, or Water Park

Cruise use
For cruise travelers, the 4-pack format is excellent. Assign one to each person and keep phones, keycards, and some cash dry even during spray on deck, tender rides, or beach excursions. The adjustable lanyard keeps your phone close in busy ports and helps prevent drops overboard or into the water taxis.

Beach days
Sand, salt, and sunscreen do not mix with bare phones. A pouch like this:

  • Keeps sand out of ports, grills, and seams
  • Protects from splash and dunking
  • Lets you shoot casual photos of the kids in the surf or a selfie waist-deep in the water

Water parks and poolside
If you plan to keep your phone with you on slides or lazy rivers, a universal pouch is the simplest way to keep it dry. Again, remember: strong impacts, fast slides, and turbulent water can stress seals—test beforehand and be sure the closure is perfectly secured.

Rainy travel and festivals
An IPX8 pouch is also a great umbrella for your phone in downpours. If you’re navigating maps in the rain or filming performances at a festival, a waterproof pouch spares your phone from waterlogging.

Beyond Phones: What Else Fits?

Because the pouch is “large size,” it can also carry:

  • Hotel keycards or cruise keycards
  • Cash, ID, metro card
  • A thin car key fob (avoid sharp keys that could puncture; wrap them or keep them separate)
  • Medication blister packs or bandages
  • A slim power bank (check overall thickness to maintain a good seal and pocket space)
    The phrase “Not just for the phone” is a core selling point, especially for travelers who want one waterproof catch-all.

How to Use and Test: A Step-by-Step Guide

Set up

  1. Inspect the pouch: Look closely at seams, latches, and the clear windows. If you see any damage, do not use it near water.
  2. Clean and dry your phone: Remove bulk cases if needed. Wipe off oils and moisture.
  3. Insert the phone: Make sure the camera window aligns with the camera cluster.
  4. Seal the pouch: Follow Hiearcool’s closure instructions exactly. Confirm every element is locked.

The tissue test (recommended before the first use)

  • Place a dry tissue or paper towel inside the pouch (no phone)
  • Seal the pouch completely
  • Submerge it in a sink or a bucket for several minutes
  • Remove, dry the exterior thoroughly, and open the pouch
  • If the tissue is bone dry, your seal is sound. If there’s any moisture, do not use it with your phone until you identify and fix the issue.

During use

  • Wear the lanyard securely; consider looping it through your wrist or a bag strap
  • Check the closure periodically, especially after lots of movement or activity
  • Keep sunscreen and bug spray off the pouch windows to preserve clarity

After use

  • If used in saltwater, rinse the pouch with fresh water to remove salt residue
  • Let it dry fully before storing it to avoid odors or mildew
  • Avoid leaving it on hot car dashboards or in direct sun for prolonged periods, which can degrade plastics

Performance Expectations and Real-World Considerations

Waterproofing reliability
When properly sealed and verified via the tissue test, a pouch like this can keep your phone dry even if you’re wading or snorkeling near the surface. For repeated deep submersion or serious underwater filming, a specialized housing is safer. The IPX8 rating is encouraging, but real-world “splash + movement + time” can differ from lab tests.

Touch and control
Expect good-enough performance for framing photos, starting/stopping video, reading messages, and basic navigation. Underwater taps may be inconsistent; hardware buttons are your friend. Plan to unlock by passcode or Face ID rather than fingerprints.

Call audio and speakers
In a sealed pouch, microphone and speaker performance will be muffled. You can still receive emergency calls or messages, but it won’t sound normal. Consider waterproof earbuds if you need better audio in wet conditions.

Condensation and fogging
Temperature changes (hot beach to cool water) can cause condensation inside any sealed pouch. To reduce fog:

  • Insert the phone and pouch at ambient temperature
  • Keep moisture out when sealing (dry hands, dry phone)
  • Add a tiny desiccant packet if you have one, ensuring it can’t scratch the screen

Safety and Durability Tips

  • Avoid sharp items: Keys and metal edges can puncture soft plastic. If you must carry them, wrap them or store separately.
  • Don’t assume flotation: Unless stated otherwise, treat it as non-floating. Consider adding a floating strap.
  • Heat exposure: Plastics can warp or fog under intense heat. Shade the pouch when not in use.
  • Lanyard safety: In active water, a dangling lanyard can snag. Tuck it inside life vests or tighten it close to your chest on slides.
  • Replace when worn: If you see creases turning white or seams looking tired, retire the pouch.

The Value of a 4-Pack

Traveling with family or friends? A 4-pack means everyone gets protection without arguing over who borrows the one dry bag. It’s also handy for:

  • Backups: Keep a spare in your daypack in case one goes missing
  • Mixed uses: Dedicate one pouch to cash/cards, one to phone, one to camera, one to keep dry napkins or small first aid items
  • Gifts: A thoughtful, practical add-on for a travel buddy

Buying Considerations and Alternatives

Hiearcool’s 4-pack hits a sweet spot for price and convenience. Alternatives include:

  • Individual universal pouches (JOTO, Moko, Yosh, etc.): Good if you only need one
  • Floating cases: Bulkier, but help prevent drops to the bottom of the pool or lake
  • Hard housings (dive-rated): Far more expensive, designed for deeper or longer underwater filming

When deciding, weigh:

  • Activity: Casual splash vs. snorkeling vs. diving
  • Photo needs: Occasional vacation snaps vs. dedicated underwater videography
  • Budget: A 4-pack usually offers better per-unit value
  • Comfort: Lanyard style and adjustable length

Pros and Cons

Pros

  • IPX8 waterproofing up to 100 feet (per manufacturer)
  • Large universal fit (up to 8.3″) for big phones including iPhone 14 Pro Max and many Samsungs
  • 4-pack is perfect for families or multiple devices
  • Detachable, adjustable lanyard (13.8–21 inches) for hands-free convenience
  • Protects more than phones (ID, cash, cards)
  • Clear windows for framing shots and checking messages
  • Lightweight, packable, affordable

Cons

  • Not a rugged drop-proof case; it’s for water, not impact
  • Touchscreen responsiveness underwater is limited (as with all pouches)
  • In-screen fingerprint sensors typically won’t work through the film
  • Potential for condensation in big temperature swings
  • Must be sealed properly every time; user error can compromise protection
  • No explicit claim of flotation—don’t assume it floats with your phone inside

FAQs

Does the Hiearcool pouch fit my phone with a case on?

  • It depends on your case’s bulk. Slim cases usually fit, but rugged or wallet cases may require removal. The pouch supports phones up to 8.3 inches in length; overall thickness also matters for a smooth seal.

Will Face ID and fingerprint work?

  • Face ID generally works, though glare and fog can interfere. In-screen fingerprints usually don’t work through pouch film. Expect to use a PIN or passcode.

Can I take photos underwater?

  • Yes, within reason. For best results, start the camera above water, use volume buttons as shutter, minimize glare, and avoid long deep submersion. For serious underwater footage, consider a dedicated housing.

Is it really waterproof to 100 feet?

  • The rating states up to 100 ft (30 m) per IPX8. That’s a lab specification; real-world conditions vary. Always perform a tissue test, seal the pouch carefully, and avoid extended deep submersion or high-impact water activities.

Does it float?

  • The listing does not claim flotation. Plan as if it does not float. If you need buoyancy, add a floating strap.

Can I still make calls or hear audio?

  • Calls will sound muffled. You can take calls in a pinch, but it won’t be ideal.

How do I prevent fogging?

  • Insert your phone when everything is dry, avoid trapping humid air, and consider a tiny desiccant packet. Keep the pouch shaded when not in use.

What else can I store?

  • Cards, cash, slim fob, small documents, or a compact power bank—just avoid sharp objects.

Best Practices for Stress-Free Use

  • Test first: Do the tissue test before trips or big water days.
  • Double-check seals: Get in the habit of inspecting the closure every time.
  • Keep it clean: Rinse after saltwater; sunscreen can cloud clear windows—wipe it off quickly.
  • Backup plan: Don’t count on flotation; attach to a secure point or use a buoyant accessory.
  • Use the lanyard smartly: Adjust to keep it close and reduce snag risk.

Travel Scenarios Where It Shines

  • Cruise shore excursions: Keep a phone, ID, and cash dry while snorkeling, boating, or tendering to shore.
  • Theme parks and water parks: Wear it on rides; worry less about splash zones.
  • Beach and pool days: Protect from sand, splash, and sunscreen.
  • Rainy cities and hikes: Navigate with maps in downpours without juggling umbrellas and zip bags.
  • Kayaking/paddleboarding: Quick, reliable protection against drips and occasional dunking.

Sustainability and Care

While soft-plastic pouches aren’t inherently eco-focused, longer-lasting gear means fewer replacements. To extend life:

  • Rinse after salt or chlorine exposure
  • Avoid prolonged UV bake in direct sun or hot car interiors
  • Store flat, not tightly crumpled, to prevent crease fatigue
  • Retire pouches that show wear, stiffening, or seam stress

What Sets Hiearcool Apart?

  • Generous size: Up to 8.3 inches accommodates today’s big phones
  • 4-pack convenience: Great for families or for keeping spares
  • Adjustable lanyard range: 13.8–21 inches is a nice usability touch
  • Straightforward, universal design: No app, no special case compatibility required

Price and Value

Universal pouches are some of the most cost-effective travel accessories per use. The 4-pack format multiplies that value, especially when split among family or friends. Pricing can fluctuate, so it’s best to check current deals:

How It Compares to Other Waterproof Options

  • Universal single pouches: If you only need one, a single unit can be slightly cheaper. But for families, a 4-pack is often better value.
  • Floating cases: Worth it if you’re in open water and drop-prone, but they’re bulkier in pockets and photos can be trickier.
  • Rugged phone cases: Offer drop and dust protection for daily use, but only some are swim-safe, and most don’t promise deep submersion performance.
  • Professional housings: They transform your phone into an underwater camera system—but at a steep price and with more complexity.

A Balanced Take: Expectations vs. Reality

Expectations the Hiearcool meets:

  • Keep your phone, cards, and cash dry in rainy, splashy, or shallow-water scenarios
  • Let you capture casual vacation photos without risking your phone
  • Provide peace of mind on cruises, beaches, water parks, and paddle sports
  • Offer easy carry with an adjustable lanyard
  • Deliver strong value, especially in a 4-pack

Limits to keep in mind:

  • Underwater touch is imperfect; volume buttons work better as shutter controls
  • In-screen fingerprints are unlikely to work
  • Extended deep submersion or high-impact water activities are risky for any soft pouch
  • It’s not a drop-proof solution

The Bottom Line: Should You Buy It?

If you’re planning a cruise, beach stay, lake trip, or water park adventure—and especially if you’re traveling with family—the Hiearcool Waterproof Pouch 4-Pack is a smart, budget-friendly pick. It covers the uncomfortable “what if” scenarios around water with a simple, universal solution. The large fit, adjustable lanyard, and IPX8 rating check the right boxes, while the 4-pack format multiplies value and convenience.

For casual snorkeling, wading, boating, and all-weather travel, it’s hard to beat the peace of mind per dollar. If you’re expecting heavy underwater filming or deep dives, consider a dedicated housing; otherwise, this set is exactly the low-hassle insurance your phone needs at the pool, on deck, and shore-side.
