The women’s-specific Osprey Viva 50 boasts a simple, clean design. Along with a pared-down shape, this durable pack is easily adjusted to accommodate various torso shapes without sacrificing comfort.Dual side compression straps provide load stability and the LightWire™ peripheral frame transfers the weight to your hips where a Fit-On-the Fly™ hipbelt easily adjusts up to three inches for a custom fit. In addition, the torso length has five inches of adjustment making this pack a shape-shifter capable of quickly adapting to many torso sizes.The backpanel is made of mesh for ventilation and comfort during periods of high exertion—i.e. when you’re trudging up a south-facing slope carrying an overnight pack in the hot sun. Two mesh side pockets and a front mesh stash pocket combine with dual zippered hipbelt pockets provide a plethora of on-the-go storage options.To expedite packing, the sleeping bag compartment is separate from the main compartment and the external sleeping pad straps are removable when you’re going ultra-light. Stow-on-the-Go™ Trekking Pole attachments allow you to quickly secure poles when not in use.
