The Riding Pack Backpack from Poler.
A fully functional snowboarding or bicycling pack. Perfect for daily use on the bike, the outer flap can hold your helmet or a change of shoes, keeping them separate from the internal pocket. Featuring a slim profile and a chest strap with a removable waist strap to keep the pack close to your body with no unnecessary bulk.
Additionally features internal or external shovel storage, vertical or horizontal board carry and a key pocket. Room for the basics while keeping it minimal and functional.
