The 2009 GoLite Vo24 backpack is a great lightweight pack for adventure racing and hiking.

Super durable Velocity fabric is polyurethane-coated and DWR-treated for extreme water resistance. The paneled back with air-channel and space mesh is comfortable and quick drying. Brock™ foam padding in the shoulder straps provides maximum support and ventilation. Supports loads up to 25 lbs.

A large rear mesh "stuff-it" pocket accommodates extra gear, and lashes down securely thanks to a bungee cord system. Two side angled mesh pockets and bellowed pockets on the hip belt allow easy access to important items. Two side compression straps keep everything compact and tight.

Fit and functionality are very good. Padded and contoured shoulder straps combined with a wide waistbelt give a solid fit. The sternum strap has 5 inches of adjustability. The waistbelt has two mesh pockets that are large enough for energy bars, compasses, etc.

The main compartment is accessed by a water resistant zipper that runs around the top half of the pack. Inside the pack is a 3 liter hydration sleeve and hook for holding the hydration bladder. Hydration tube ports are above each shoulder strap. On the rear of the pack are a tow loop/light clip, X-cord compression system and 2 ice axe loops.
