Osprey VIPER 13

Osprey Packs redesigned its popular Viper and Verve bike hydration packs, utilizing its new Hydraulics LT Reservoir in a lighter yet high-performance cycling pack, now available in a full three-liter capacity for desert riding, compatible with three pack sizes. The Viper 13 ($110) performed like all our Osprey packs – swimmingly. Even though it’s a small pack, the Atilon foam framesheet helps spread the load and moves with your body while riding. Osprey’s Airscape mesh-covered foam provides some of the best ventilation on the market. Although you’ll always be sweating back there. The Biostretch Harness with mesh-covered die cut foam provides a secure, comfortable, slightly breathable suspension, especially when the 20mm webbing hipbelt is in use. Side-stretch mesh pockets are ideal for stuffing bike tubes and gels, and interior pockets organize patch kits, tools, jackets and other sundry necessities.
