Osprey Ultralight Dry Sack 20L is a lightweight and practical stuff sack that keeps gear organised and protected inside rucksacks and travel luggage. The rectangular shape makes the sack easier to pack efficiently, and the 20-litre volume is well suited to clothing, sleeping bags, and other kit you want to keep dry.

The range is available in several sizes and four different colours, so contents can be sorted as needed or colour-coded for better overview.

The stuff sack features a waterproof roll closure that keeps out moisture, and both the fabric and seams are coated to provide reliable protection. It is rated to IPX5 level, meaning it withstands heavy water spray but not submersion. A D-ring makes it easy to hang the sack up to dry or attach it to other luggage.
