Osprey Dry Sack

The rectangular shape is designed to stack more efficiently inside your backpack, eliminating the dead space that often occurs with cylindrical bags. It helps you create a more stable, organized pack structure, which is particularly useful when you are trying to fit multiple items into a limited space.

It features a secure roll-top closure and coated seams to keep your gear dry in wet conditions, such as rain or splashes. However, it is not designed to be submerged underwater for extended periods, so it should not be used for activities like kayaking where full submersion is likely.

The 6-liter capacity is ideal for organizing smaller essentials like extra socks, base layers, or toiletries. It is small enough to tuck into the corners of a larger pack, helping you separate clean clothes from dirty gear or keeping electronics protected from moisture.

No, the PFAS-free DWR (Durable Water Repellent) finish provides the same reliable moisture protection as traditional coatings while being a more environmentally conscious choice. It effectively beads water off the surface of the fabric to keep your contents dry.

The Osprey Ultralight Dry Sack is not transparent, so you cannot see the contents through the fabric. If you have multiple sacks, we recommend using different colors or labeling them to keep your gear organized and easy to identify.
