Osprey Waterproof Dry Sack 6L Ultralight — Green rectangular packable organiser, IPX5 protection

Osprey Ultralight 6L Waterproof Dry Sack in green is a compact, rectangular roll-top dry bag that keeps a 6-liter load organized and protected from splashes and rain inside packs or luggage.

Designed for hikers, travelers, and everyday packers who need a lightweight weather-resistant organizer, this 6-liter dry sack balances protection with minimal bulk. Its rectangular shape nests neatly in backpacks and suitcases, while waterproof-coated fabric and taped seams shed moisture on wet trails or rainy commutes. The D-ring lets you hang the sack to dry or clip it inside a larger pack, and its ultralight 0.07lb weight means it won’t add noticeable heft to your kit. Osprey offers the same design in multiple capacities and colors so you can color-code gear by use.

How does this dry sack fit inside a backpack or luggage?

The rectangular profile is engineered to use space efficiently, sliding into corners and compartments where round dry bags leave gaps. Its slim footprint makes it ideal for vertical packing pockets or stacking with other accessories.

• Rectangular dimensions: 11.4" H x 7.1" W x 5.5" D for predictable placement
• Flat base helps it stand upright when partially full
• Roll-top closure keeps the profile compact once sealed

What level of water protection can I expect from the Osprey Ultralight 6L?

This dry sack delivers splash and rain protection through waterproof-coated fabric and taped seams; it meets IPX5 standards, which resist water jets but does not guarantee submersion. It’s ideal for protecting electronics, clothing, and documents from wet weather and accidental moisture.

• Waterproof-coated fabric for surface water resistance
• Taped seams to limit seam leakage
• Roll-top waterproof closure for a secure seal
• IPX5 rating indicates protection from water jets, not full immersion

How light and packable is the 6L Ultralight Dry Sack for travel?

At just 0.07 lb, this sack adds practically no weight to your load while still organizing and protecting essentials. Its minimal material and compressible shape make it easy to stow when not in use or to nest multiple sacks together for modular packing.

• Ultralight construction for weight-conscious trips
• Compressible design fits inside small pockets or larger duffels
• Available in several volumes so you can choose the right capacity

What practical features help with hanging and attachment?

A reinforced D-ring adds simple utility: clip the sack inside a pack, hang it to air-dry, or fix it to a carabiner on a harness or belt. The attachment point is useful when you want quick access without unpacking everything.

• D-ring for hanging to dry or attaching to gear
• Roll-top makes a compact handle when folded over
• Works with carabiners or internal pack straps for secure placement

Who is this for? The Osprey Ultralight 6L Waterproof Dry Sack appeals to day-hikers, bike commuters, minimalists on multi-day treks, and travelers who prefer organized luggage. If you want a lightweight, space-efficient way to separate wet or valuable items from the rest of your pack without adding bulk, this 6-liter rectangular dry sack is practical, simple, and easy to integrate with existing Osprey gear.
