Something about this vest reminds us of a B-52 Stealth Bomber. It’s sleek design and superb construction takes Hydration vests to levels they have never been before. It currently has the best volume-to-weight ratio of any running vest or pack on the market. It is stealthy, ultra-comfortable, functional and FAAAAAST. 

It’s 11L storage capacity and easy to access pockets make it a perfect vest that can take you all the way to your next 100 miler. Incorporating Ultimate Direction’s famed Comfort Cinch Technology, that allows you to adjust your fit whilst running, the Halo offers minimal bounce no matter how full or light your pack is.
