osprey viper 4 hydration pack 200x300   Osprey Viper 4 Hydration PackOsprey adds new packs to its Hydraulics line, the Viper (for men) and the Verve (for women). The Osprey Viper 4 will soon be out on 2011. It weighs 420 grams without its reservoir and can carry a capacity from 4 to 13 liters.

The Osprey Viper 4 will turn heads with its soft on the back feel yet durable and sturdy exterior. It features Osprey’s Lid Lock system so you attach your helmet on the bag easily. It has several straps to keep the Viper 4 in place on your shoulders and even has a gel pocket on the strap which you can place your mobile phone.

The new hydration pack has a thin waist strap, top tensions and a shock corded accessory patch. It has a small zip pocket while the main compartment will be shared by your things and the reservoir.

The back portion of the Viper 4 has a flexible plate, mesh covered foam and press-stud closure. The Osprey Viper 4 and the Verve are stripped down to save weight but retains its functionality to meet the demands of any cyclist.
