Our View – Ultimate Direction Ultra Vest 6.0: The Ultimate Direction Ultra Vest 6.0 takes yet another step forward in the evolution of the long-distance running vests designed specifically for racing & training. Building on the success of the previous versions the latest model takes onboard customers feedback to provide an even comfier, more practical trail running pack. The Ultra Vest 6.0 uses the latest in fully customisable vest-fit technology with the ultra-durable Comfort Cinch™ 3.0 with added protective mesh panels that prevent chafing over many miles. Adjustment of the Comfort Cinch is now also centred for one hand on the fly changes and to ensure equal adjustment to each sid. A roomier cut in the back and spacious arm holes provide a wider, taller fit ideal for larger frames compared to the vesta version. The new pack features several waterproof and water-resistant pockets to help increase the protection of contents and the trekking pole attachment also allows you to choose between front or back mounting. With 10 Litres of carrying capacity the Ultra Vest 6.0 swallows a surprising amount of kit and thanks to the 2-front mounted soft bottles (included) and the ability to carry a 2-litre reservoir (not included) hydration is also well taken care of. We think the new additions and alterations to the Ultra Vest 6.0 are going to make this a hugely sort after version for long distance trail runners and racers.
