Perfect size for my 40-degree sleeping bag and the clothes I sleep in. Fits perfectly into the Arc Blast sideways. I love how all of the Zpack bags keep my Arc Blast organized and tight to my back, and I never have to worry about anything getting wet!!

Keep your gear dry and dust-free without adding any more weight than you have to. This size will fit multiple clothing items or an average-sized ultralight sleeping bag. It fits well horizontally in most backpacks.
