Duro, brand new for Spring '17, uses Osprey's renowned attention to detail & an uncompromising range of features to provide a phenomenally high-performance running pack. Duro 6 is a medium capacity running pack designed to support distance athletes who require the space to hold water, clothes, food & equipment. The pack is built with a vest style fit, allowing for a comfortable carry & avoiding bounce. Duro 6 is lined with contact mesh, allowing it to be comfortable & breathable, even when the going gets tough. Multiple stretch mesh & zippered pockets on the front of the vest allow for easy, on-the-move access to nutrition & equipment. The upper vest pockets contain two 500ml soft flasks with extension hoses, which can be swapped in & out. Compression straps ensure that the pack has a close fit, whilst the large stretch-mesh pocket easily stores a waterproof jacket or hat & gloves. The rear of each shoulder features a Stow-on-the-Go™ loop, which can comfortably & efficiently carry trail running poles, keeping them out of the way & your hands free. The sternum straps are removable & adjustable, with a single hand release, as well as being elasticated so they don't inhibit deep breaths or energetic movements. Duro 6 was born to run, ideal for those who wish to push themselves on the trail. Duro 6 is compatible with all Hydraulics™ reservoirs.
