The Osprey Viper 13 is the largest of the Viper Series with 800 cubic inches of storage capacity, a decent amount for sure. It’s big enough for many day-long rides yet small enough to be considered a marathon pack. With the proven 3L large mouth Hydraform bladder you get one of the best bladders on the market plus key compartments to help you organize your gear. The large hose and decent bite valve on the included bladder both work great and the reservoir didn’t leak on me. The bladder, which I can’t rave about enough, works, fits, and cleans well. The molded form ensures that even if filled to the brim with water, you don’t feel like there’s a salami on your back.
We’ve been singing the praises of the Osprey hydration packs that were introduced this year and for 2011 the company is diving even deeper into the bike scene. The Momentum (yellow pack in photo below) is geared toward commuters, though urban mountain bikers will love the hydration compatibility, LidLock helmet attachment, and U-lock pocket. This pack is so new there isn’t any info on Osprey’s website or in the pamphlets they were handing out.
Not too long ago trek7k did a write up on the Osprey Raptor 6 and if you recall he raved over its sleek and comfortable design. Today I’m writing about another offering in the Osprey hydraulics line-up – the Manta 20. Unlike the Raptor, the Manta is a larger pack designed for day trips and epic rides.
The Osprey Raptor 6 is a hydration pack with wings – or at least it feels that way. This sleek pack swallows 2L of water and a surprising amount of gear without harshing your ride. In fact it might just be the most comfortable hydration pack we’ve ever tested.
Osprey has made a name for itself over the years for producing high quality packs for multi-day hiking and camping trips and that experience shows in the Raptor 6, one of the first bike-specific packs from the company. Osprey spent 3 years and rolled through 100 prototypes before releasing the 2010 Raptor series. The hydration pack is covered in a reflective, rip-stop material with mesh venting in the back to keep you cool on hot rides. Stretchy material on the waist straps provides additional comfort while the same material is used on the outside front pocket for expandable storage. The strapping system is intuitive and makes it quick and easy to get a customized fit.
