Dry kit, whatever the weather

The 5.11 Ultralight Dry Bag 20L is built to keep your gear bone dry when the conditions turn against you. A 40D nylon ripstop shell is treated with a silicone and UTS waterproof coating, and every seam is double-stitched then tape-sealed, so rain, spray and splash stay firmly on the outside. For UK airsoft skirmishes, kayaking or a wet day in the field, that means clothing, electronics and food come home usable.

Roll-top security

The roll-top closure with quick-release buckle is quick to use and forms a reliable watertight seal once folded down. Press out the air, roll the top several times and clip the buckle: contents are protected and the fold doubles as a carry handle. A D-ring on top lets you clip on spare gear or secure the bag inside a larger pack.

Ultralight, big capacity

At roughly 50 grams empty, this 20 litre bag adds next to nothing to your load, yet it holds a full change of clothes, a towel or a chunky loadout. When it is only part full, roll it down further to save space.

Frequently asked questions

Is the 5.11 Ultralight Dry Bag fully submersible?

No. It carries a 2k waterproof rating and is designed to keep contents dry from rain, splash and spray. Roll and buckle the top properly and it will shrug off wet conditions, but it is not rated for prolonged submersion underwater.

How much will a 20L dry bag actually hold?

Around 20 litres, which comfortably swallows a spare base layer, fleece, socks, a towel and a few small items, or bulkier kit for an airsoft weekend. The roll-top means you can cinch it down smaller when it is only part full.

How do I close the roll-top correctly?

Press the air out, fold the top down at least three times, then clip the quick-release buckle. Rolling it tightly is what forms the watertight seal, so do not leave it loose.

Can I attach it to a rucksack or belt?

Yes. The buckled roll-top forms a carry loop and there is a D-ring on top, so you can clip it to MOLLE, lash it inside a pack or hang it from a rail while you work.

Does it come in other sizes?

5.11 offers the Ultralight Dry Bag in smaller volumes such as 5L for phones, wallets and documents. The 20L is the go-to size for clothing and larger loadouts.
