5 litre compression drybag.

A vacuum seal storage bag that will allow you to reduce the volume of packed items by up to 80%. It works great for sorting things when packing, you can put dirty laundry in it, thereby keeping it separate from clean clothes, for example. In addition to hiking, you’ll also appreciate it for water sports - if you don’t push air out of the pocket, it works as an inflatable buoy that floats on the surface.
