Keep your essential kit bone dry

The Viper Tactical Lightweight Dry Sack is built to do one thing brilliantly: keep water out. Made from PVC polyester with a roll-top sealing system, it is 100% waterproof, so your spare layers, electronics, documents and first aid kit stay dry even in driving rain or a river crossing. This is the medium size at 18 x 29cm, around 10 litres of usable space.

Simple, secure roll-top seal

Fill the sack, squeeze out excess air, roll the top down and clip the buckle. That rolled closure is what makes it watertight, and the buckle doubles as a carry handle or a clip-in point inside your pack. No zips to fail, nothing to leak.

Barely there weight

At roughly 50g it is genuinely lightweight and packs flat when empty, so there is no reason not to carry one. Use it to separate dry kit from wet kit, corral loose items, or protect anything that must not get damp.

Field-ready camo

Finished in Viper’s VCAM pattern, it blends neatly with the rest of your loadout for airsoft and milsim, while working just as well for hiking, kayaking, cycling and travel. Add more tactical gear to complete your setup.

Frequently asked questions

How waterproof is it?

The Viper Lightweight Dry Sack is made from PVC polyester with a roll-top seal, making it 100% waterproof. Roll the top down at least three times and clip the buckle to lock water out.

What fits in the medium 18 x 29cm size?

The medium size, roughly 10 litres, is ideal for a spare base layer, socks, a phone and battery pack, a first aid kit or snacks. It is a handy everyday dry bag size.

How heavy is it?

Very light at around 50g, and it packs down flat when empty, so it adds almost nothing to your pack until you need it.

Can I use it to separate wet and dry kit?

Yes, that is exactly what it is designed for. Keep dry layers sealed inside, or use it to isolate wet or muddy kit away from the rest of your gear.

Is it just for military use?

Not at all. It suits airsoft, hiking, kayaking, camping, cycling and travel. Anywhere you want to guarantee something stays dry.
