Dehydration on the trail is not an option. One, maybe two bottles tucked into cages on your bike only supply so much fluid. A backpack hydration system such as the Osprey Packs Hydraulics line Raptor Series gives you 2- and 3-liters of H20. The Raptor Series is focused on mountain biking and trail running, giving you a few pockets to stash gear in a streamlined design. Osprey puts a great deal of design into its pack.
Start with the water reservoir. Three of the four Raptor styles come with 3-liter reservoirs; the streamlined Raptor 6 has a 2-liter capacity. The reservoir is built with a plate that aligns with the contours of your back so the water doesn’t barrel. You won’t feel the shape of water as it all buckles at the bottom of the tank while you ride. The framework of the straps are constructed by perforated molded foam to create a lightweight and flexible support. The same foam is ridge molded to create a ventilated back panel. Lightweight webbing adds reinforcement surrounds both the straps and back panel. The A LidLock helmet clip straps through the vent holes on your helmet — when you’re off the bike — so the two stay together and ready to pick up and go. The bite valve rotates to an open and closed (no leak) position, and has a magnet so the sip portion stays in a handy location on your sternum strap instead of flying around with every bump on the trail.
Features are too many to go into. Research, trials, and serious evaluation went into the development of the Raptor Series hydration packs. Every pocket, strap, and tab is built for a specific need while the unnecessary bits of a backpack were left out to keep the pack lightweight and streamlined for a more enjoyable ride.
