Osprey Ultralight Zipper Sack

The 7L size is ideal for organizing medium-sized items like t-shirts, base layers, or a light sweater. It helps keep your clothing compressed and separated from the rest of your gear inside your luggage.

Yes, the sack features a built-in D-ring attachment point. This allows you to hang it from a hook or carabiner, which is particularly useful in small hotel bathrooms or tight cabin spaces.

The sack is made from 40D high-tenacity nylon, which offers a degree of protection against light moisture and spills. However, it is not fully waterproof or submersible, so it should not be used to protect sensitive electronics in heavy rain.

Unlike compression cubes that use secondary zippers to shrink volume, this sack is a standard zippered pouch. It is designed for lightweight organization and keeping items grouped together rather than actively compressing the volume of your clothing.

The 40D nylon is chosen specifically for its balance of high strength and low weight. While it is thin to save space, the high-tenacity construction is designed to withstand the rigors of regular travel without tearing.
