20161205_100340 Ultimate Direction have established themselves as one of the best designers and manufacturers of running vests and the new Jurek FKT Ultra Vest adds to this reputation with a fully featured, elite athlete tested design... Every feature on every Ultimate Direction pack has been thoroughly researched, tested and developed to meet the specific demands of trail and ultra running. The Jurek FKT Ultra Vest has been deigned in collaboration with Scott Jurek and was developed during his record breaking Appalachian Trail fastest know time (FKT) run. Facing 46 consecutive days of extreme terrain is certainly a test for any equipment! The Jurek FKT Ultra Vest builds on the hugely successful SJ Ultra Vest 3.0 but with a carrying capacity of 11.6 Litres as opposed to 8.5 Litres. This means the FKT is even better suited for longer events and training and the 2 Litre compatible bladder compartment also adds to the packs use for longer outings. An additional update to the Jurek FKT is the new FlexForm 600 body bottles which sit perfectly into the front bottle holsters and mould to the body to prevent movement and bounce. As with all the Ultimate Direction vests the fit and comfort of the Jurek FKT is exceptional with the materials allowing the pack to fit like an item of clothing rather than an accessory. Adjustable chest straps and additional adjusters in the side pockets mean you can personalise the fit and tweak the fit on the fly as content volume changes to help maintain a perfect no-movement fit.
