The Analog Siphon Backpack is a nifty little nylon/poly gear bag with skater-friendly features. Starting with skate straps in the front, the Analog Siphon doesn't stop there. You get a place for everything in this great backpack, including integrated laptop pocket, lined compartment to safely stow your MP3 or shades, and a special magazine holder sleeve so you'll have something to read while you wait your turn on the halfpipe. As always, Analog built this backpack to withstand your active lifestyle, using tough nylon/poly underlaid with perforated leather.
