Osprey Duro 1.5 is an ultralight and minimalist running vest developed for trail runners and competitors who want maximum freedom of movement without sacrificing space for liquids. The vest is made from 100% recycled materials and sits close to the body for stable, balanced carrying, even at high speed. Two soft Hydraulics™ bottles of 500 ml are included, making it easy to stay hydrated when there is a long way between water stations.

The model has several elasticated pockets in the harness system that provide quick access to nutrition and small items, as well as a vertical zip pocket for valuables or a mobile phone. An elasticated front pocket allows for quick stowing of extra gear on the go, and a drawcord storage area at the front offers flexible space for what you need within easy reach.

The adjustable and removable chest straps conform to the body and provide a secure fit without bounce. The vest also features attachment points for poles or an ice axe, an integrated emergency whistle, and open side pockets for practical storage on the move.
