Never be without a backpack! This ultralight sil-nylon pack stuffs into a built in pocket (6in x 10in x 2.5in) that can be worn as a hip pack or tucked away inside your carry on. When you need extra capacity it unfolds into a full featured day pack. Padded shoulder straps (with ear bud garages) and adjustable sternum strap make the Go and Stow Travel Pack a comfortable way to carry the essentials. Water resistant zippers.
