Osprey Ultralight Waterproof Dry Sack

The Osprey Ultralight Waterproof Dry Sack is a go-anywhere storage solution for keeping your gear dry. Featuring a roll-top waterproof closure and waterproof-coated fabric, this dry sack meets IPX5 standards, meaning it can withstand heavy rain and splashes—perfect for kayaking, hiking in wet conditions, or organizing your pack. It's part of Osprey's coordinated packing system, designed to help you stay organized on every adventure.

Is the Osprey Ultralight Waterproof Dry Sack Really Waterproof?

Yes, it's IPX5 waterproof, which means it resists water jets and heavy rain. However, it's not submersible (IPX7 or higher), so don't intentionally dunk it. The roll-top closure, when rolled three times and clipped, creates a watertight seal that keeps contents dry in wet conditions.

What Does IPX5 Mean?

IPX5 is a rating that indicates protection against water projected from a nozzle, making it suitable for rain, splashes, and wet environments. It's not designed for full submersion, but for most outdoor activities, it's more than enough to keep your gear safe.

Ultralight and Packable

Weighing just 0.06 lb (about 27 g) and packing down small, this dry sack adds negligible weight to your pack. It's available in multiple sizes to suit different needs, from organizing electronics and clothing to storing a sleeping bag.

Sustainable and Durable

The main body fabric is bluesign-approved and made of 100% recycled materials, with PFAS-free DWR treatments. This means you're choosing gear that's better for the planet without compromising on performance.
