Stahlsac Abyss Drylite Scuba Diving Dry Bag

Stahlsac Abyss Drylite Dry Bag: Lightweight Roll-Top Dry Bag for Water Sports and Dive Travel

The Stahlsac Abyss Drylite is a roll-top dry bag built to keep your gear dry and your pack uncluttered, whether you are heading to the dive boat, the river, or any wet environment where your phone, wallet, and clothes need real protection.

If you are a recreational diver looking for a reliable way to protect your valuables at the surface, this is the kind of practical accessory that earns its place in your kit bag on every trip.

What it is and how it works

A roll-top dry bag works by rolling the open end of the bag down several times and then clipping or securing it shut. That folded seal is what keeps water out. No zippers, no flaps, just a tight mechanical closure that holds up in wet conditions.

The Drylite uses this proven system, and its RF-welded seams back it up. RF (radio frequency) welding fuses the material together rather than stitching it, which means there are no needle holes for water to creep through. The seams also sit flat, which matters when you are trying to pack the bag away.

Materials and build

The bag is made from lightweight nylon that resists both UV exposure and salt corrosion. Those two things matter specifically for diving and boating use, where gear lives in direct sun and saltwater repeatedly over a season.

The flat-pack design means the empty bag compresses down small enough to tuck into a BCD pocket or the corner of a travel bag. It is not rigid, it does not have a frame, and it takes up almost no space when you do not need it.

Sizes and weights

The Drylite comes in four capacities. Here is what each one weighs and measures when empty:

For most divers, the 6L or 12L handles the essentials: phone, wallet, keys, and a change of clothes for after the dive. The 18L and 25L make more sense when you are carrying extra layers or a full day's worth of gear to a remote site.

The removable strap

The bag includes a removable shoulder strap that converts it into something you can carry like a backpack or sling over one shoulder. This is genuinely useful on a dive boat or at a beach entry, where your hands are often occupied with fins, a mask, or a camera.

When you do not need the strap, it comes off and you can store it separately, keeping the bag compact.

Who this suits and who it does not

The Drylite is well matched to recreational divers who want a light, packable dry bag for protecting personal items on the boat or at the water's edge. It is also a practical travel companion, since it packs flat in a suitcase and can serve multiple purposes on a dive trip.

It is not a submersible case. Do not expect to take it underwater or use it to protect a camera rig at depth. It is designed to keep contents dry from splash, rain, and wet surfaces, not from full immersion under pressure.

If you need a hard case or a waterproof housing for electronics that will actually go in the water, this is not that product. But for everything you want to keep dry at the surface, the Stahlsac Abyss Drylite does the job without adding bulk or weight to your travel kit.
