The new-generation UltRun S Pack Evo 10 earned no less than 4 top-10 results over all 2021 events, proving it's here to mix it up with the best. UltRun S Pack and evolved it for even more performance. Smaller than its Evo 15 counterpart, the Evo 10 model features a novel, zig-zag elastic closure system on the front that allows the chest to expand as the tempo builds, making it ideally suited to shorter, higher-intensity efforts. On the chest, two easy-to-reach mesh pockets hold soft flasks, with dedicated drink valve tabs to reduce movement. Foam inserts on the front prevent any rubbing on the ribcage.

Smaller pockets securely hold keys or used wrappers. Stow your gloves, headband, headlamp, energy gels and more food in the larger lower compartments, which are easily accessed thanks to convenient tabs. A diagonal zipped pocket on the left-hand side keeps your phone within hands reach to check the route or stay in touch with your support crew. On the back, a large compartment holds all your compulsory gear such as full tights, long-sleeved baselayers, waterproof pants and survival blanket. The two large overlapping pockets stretch to accommodate a rain jacket and any extra equipment, while low-placed silicone toggles keep retracted poles out of the way when the trail doesn't require them. True to Compressport standards, the vest is highly breathable and ergonomic, with soft seams for unmatched comfort. It is developed to be one of the most stable running vests on the market today, with absolute minimum vertical movement out of the trails.

Adjustable side straps can be pulled tighter for added stability on technical sections. Reflective details provide improved visibility in low light conditions and the included whistle means you can head out with full peace of mind. The UltRun S Pack Evo 10 can easily be combined with a Free Belt for more capacity over longer efforts. Featherlight and bounce-free, this is the choice of fast trail runners looking for those all-important marginal gains.
