Osprey Viper 5 Hydration Pack
The Osprey Viper is a hydration pack designed for riders who want a great quality pack created with simple styling. This pack is high-performing, light, and versatile. New features for this year include a front shove-it pocket and fresh vibrant colors. The Viper 5 is the smallest of the Viper series so it's great for short blasts on the mountain.
This pack is great for short (1-2 hour rides). It's laid out well and has just enough room for the items you need to take on these loops (tube, pump, patch kit, multi-tool). It also leaves enough room for some chews, keys, phone, glasses and a light wind breaker. There is more than enough water capacity for even hot rides of this length. My only complaint would be the reservoir cap. I find it a little troublesome to get closed and have even thought is was closed and had it leak in the pack. Poor design and kind of surprised considering all the other great features.
