Osprey Zipper Sack

This sack is ideal for corralling small, loose essentials that typically get lost in the bottom of a larger bag. Think charging cables, power banks, toiletries, or small first-aid supplies.

While the sack is made from durable recycled polyester, it is not fully waterproof. It will protect your items from dust and light splashes, but it shouldn't be submerged or exposed to heavy rain.

The sack is designed with a slim, minimalist profile that allows it to stack or tuck alongside other Osprey packing cubes and organizers without adding unnecessary bulk to your luggage.

No, the fabric is opaque. If you prefer to see your contents without opening the bag, you may want to label the outside or use a consistent color-coding system if you own multiple sacks.

Because it is designed to be ultralight and minimalist, it is soft-sided and will collapse flat when empty. This makes it very easy to store away when you aren't using it.
