Dakine's Session 8L Hydration Pack handles all your after work bike rides with its lightweight, streamlined design. When filled all the way up, the Hydrapak reservoir holds enough water for intense cross country rides, or you can leave it a little emptier when you want an ultralight setup for hair raising downhill sessions. The Phaser bite valve allows hands free drinking so you can stay hydrated without stopping. Internal organizer pockets offer storage space for extra tubes, tools, energy gels, and your keys so you always have the basics covered. Breathable air mesh straps and back panel keep you from getting completely soaked with sweat on mid summer days, and a safety light attachment and integrated emergency whistle prepare you for the worst.
