See Inside at a Glance

The clear front panel is what makes this a true transparent window dry bag rather than another opaque sack. You can locate keys, a phone or sunscreen without unrolling the top and rummaging — which matters most for the quick in-and-out of a swim or a beach afternoon. We weld the clear PVC film into the front panel so the window is part of the waterproof shell, not a glued-on patch that lifts at the edges over a season.

Quick-Release Shoulder Strap

The detachable strap clips off and on in a second, so you can sling the bag cross-body for a walk to the water, then pull the strap to pack the bag flat or hand-carry it on a paddle board. Quick adjustment means it sits right whether you are wearing a swimsuit or a jacket, and removing the strap entirely makes the bag easy to stow in a larger pack.

Buckles Tested Past 20,000 Cycles

A dry bag fails at its buckle long before the fabric gives out, so we do not leave that to chance. The heavy-duty buckles on this model are tested to withstand more than 20,000 load-bearing cycles — repeated clipping and loading that simulates seasons of real use. For a bag that gets opened and closed several times a day at the waterside, that durability is the difference between a season and a single summer.

Seamless HF-Welded Waterproof Construction

Every seam is joined with high-frequency welding, fusing the PVC waterproof fabric into a continuous shell with no needle holes for water to enter. Combined with the roll-top closure, this gives reliable protection against splashes, rain and the wet handling of swimming, paddling and beach use. As a pvc waterproof dry bag, it also wipes clean after a sandy or salty trip and rolls down small for storage.

Lightweight in Three Sizes

At 190 g, 240 g and 300 g for the 3L, 6L and 10L, this is a genuinely lightweight dry bag you can carry all day without noticing it. The 3L suits a phone, wallet and essentials; the 6L takes a towel and a change of clothes; the 10L holds a fuller day kit for swimming or a short paddle.

Does the transparent window leak?

No. The clear film is high-frequency welded into the front panel as part of the shell, so the window seals to the same standard as the rest of the welded body — it is not a glued-on patch.

How durable are the buckles?

The heavy-duty buckles are tested to more than 20,000 load-bearing cycles, so they hold up to repeated daily opening and closing through seasons of outdoor use.

Can the strap be removed?

Yes. The quick-release shoulder strap detaches in a second for fast adjustment, hand carry, or flat storage.

What sizes and colours are available?

3L, 6L and 10L, in five two-tone colourways — black & yellow, pink & green, yellow & blue, purple & white, and green camouflage — with custom combinations available.
