Osprey Ultralight Dry Sack 5L
Product description
This ultralight dry sack from Osprey keeps kit organised and protected on wet trips, offering a compact solution for packing and easy attachment. It combines a roll-top waterproof closure with taped seams and a rectangular shape that helps maximise space, making it a practical choice for day hikes and overnight outings. For waterproof storage on the move, the sack meets the IPX5 standard, meaning it resists water spray but is not designed for full immersion.
What to know
The fabric and seams are waterproof, and the rollable closure secures contents while limiting bulk. Its rectangular profile aids efficient packing into rucksacks or duffels, and the D‑ring lets you hang the sack to dry or clip it to a harness or pack. The overall design favours low weight and simplicity, so you get protection with minimal added mass. Note that IPX5 classification indicates resistance to water jets according to the manufacturer, not submersion.

Best use cases
