Zpacks Slim Dry Bag

The Zpacks Slim Dry Bag is a waterproof liner sized for smaller backpacks rather than a full pack load. It fits lightweight clothing, loose small items or a summer quilt, and its flatter profile also works well for maps, documents or anything else you want kept dry and uncrumpled. At 15 g (0.53 oz) and 4 liters (245 cu in), it's useful as a secondary liner inside a bigger pack or as the main liner in a small daypack, but not sized for a full multi-day clothing and sleep-system load.
