How AquaStash’s Waterproof Pocket Works (and How We Tested It)

When we set out to create AquaStash waterproof pocket swim shorts, the idea was simple. Most so-called waterproof gear just doesn’t hold up when you’re actually in the water. Zippers fail, clips pop open, roll tops let air out — and suddenly your “safe” pocket isn’t so safe anymore.

We wanted a solution that was automatic. No zipping, rolling, or fiddling. Just drop your phone or keys inside, let the seal close itself, and trust that it stays locked shut, even underwater. That’s how the AquaStash waterproof pocket came to life.

The Problem with Typical Waterproof Gear

Traditional waterproof bags and pouches rely on closures that depend on the user getting it right every single time. A single unrolled corner or weak zip can break the seal. Once that happens, water gets in and everything inside is done for.

That’s why we designed something foolproof. The AquaStash pocket uses Gooper® magnetic sealing technology — a system that snaps shut automatically and stays locked through water pressure, movement, and time. It’s completely airtight and submersible, certified to an IPX8 waterproof rating.

How the Gooper® Magnetic Seal Works

The closure uses a series of flexible, high-strength magnets that connect perfectly every time. As soon as the two edges meet, they align and lock together, forming a tight, uniform seal from end to end. No twisting. No guessing. It closes itself, even if you’re rushing or distracted.

It’s the same technology trusted in professional-grade dry gear — adapted for comfort and movement in wearable swimwear. That means no bulky clips, no stiff materials, and no compromise on flexibility or style.

How We Tested It

Every AquaStash pocket is tested well beyond the average “splash test.” We use a pressure chamber that simulates submersion up to 30 metres deep. We bend it, twist it, and submerge it for extended periods. It’s then retested after exposure to saltwater, sand, and UV, the real-world conditions that ruin most waterproof products.

The result? A waterproof pocket that’s proven to protect your phone, wallet, and keys through repeated use. Every pair of AquaStash waterproof pocket swim shorts carries an IPX8 certification and is backed by a three-year waterproof warranty.

Designed for Real Travel, Not Just Testing

Lab tests are great, but we wanted something travellers could rely on day to day. So, we field-test every new design on the beaches of Australia, from Noosa to Byron Bay. We swim with it. We surf with it. We test it in salt, sand, and chlorine. If it doesn’t hold up, it doesn’t ship.

And because it’s built into your shorts, there’s no separate pouch or gear to manage. It’s simply part of what you’re wearing — ready for the ocean, the pool, or wherever your travels take you.

Part of a Bigger Waterproof System

The same sealing principles are built into our broader range of waterproof travel gear. Our waterproof backpacks use welded seams and airtight magnetic seals for everyday carry. Our waterproof dry bags keep towels, clothes, and tech safe during day trips. And our waterproof pouches are ideal for those who prefer a removable option.

Together, they make a complete waterproof system for travel and adventure — whether you’re heading to the beach, the reef, or a weekend away.

The Simple Way to Stay Dry

Waterproofing shouldn’t be complicated. That’s why we built something that works automatically. The Gooper® seal removes user error completely, giving you peace of mind that your valuables are protected, no matter where you are.

FAQs

What does IPX8 mean?
It’s the highest waterproof rating, meaning the pocket can be fully submerged and still keep your valuables dry.

How is the magnetic seal different from zips or clips?
It closes automatically and evenly, removing human error. Zips and clips rely on the user to seal them perfectly — magnets do it for you.

Can I use it in saltwater?
Yes. Just rinse with fresh water afterwards to keep the magnetic seal clean and smooth.
