The Osprey Viper 9 Pack is a hydration pack for the outdoor enthusiast, whether you're a mountain biker, trail runner, or day hiker. The 9 liter pack is small in size but oh-so-sweet when it comes to providing delicious water straight to your mouth, with very little use of your hands. The BioStretch™ harness combines breathable spacer mesh with slotted EVA foam for a cool and comfy cushion against your shoulders. The sternum strap and webbing waist belt secure the pack against your body to prevent movement, but can be removed if you're not in the mood. The three zippered sections provide enough space for your sunglasses, snacks, jacket and bike tools without causing too much of a heavy load.
So sorry, but only 4 items are allowed for comparison, so we're comparing the first 4. I blame the gnomes and so should you.
