The new Flux Pull-On is a very versatile top that can be used as an extreme weather next-to-the-skin baselayer or as a lightweight midlayer for more active pursuits such as running & biking. The fabric used is a single knit jersey polyester with a soft brushed lining. The fabric has a smooth outer face which reduces friction when worn under shell garments & also resists abrasion. The soft brushed lining provides superb insulation & wicks moisture away from the skin to keep you dry when things get sweaty. The fabric is also treated with Polygiene, a naturally occurring antibacterial agent that resists the build up of odour causing bacteria & lasts for the life of the garment. Polygiene is completely safe next to the skin & is environmentally friendly, making the Flux Pants perfect for multi day trips. Featuring a nice long chest zip to help with ventilation & double cuffs with thumb loops to keep your wrists warm even when climbing & scrambling. This versatile top is superbly comfortable to wear & works brilliantly under waterproof shell garments thanks to its friction free fabric.
