Practical both as a midweight baselayer and a lightweight fleece, our easy-pack Flux Pull-On is perfect for longer multi-day climbing and trekking trips when you want to stay warm, dry and active. Our new Flux Pull-On provides versatile fast-wicking insulation. Designed to keep you dry when you work so you can stay warm when you stop, it is built from Thermic™ single jersey knit with a brushed back for outstanding comfort. It also uses low-profile flatlock seams to provide friction-free comfort next to the skin, even during extreme physical activity. The deep-venting YKK® VISLON® ® half-zip enables you to adjust the warmth to match the activity and the unobtrusive thumb loops keep the layer secure and draught-free. To help with the repeated work-rest cycles of mountain recreation, it also features Polygiene® STAYS FRESH technology, which reduces odour-causing bacteria by 99% for the entire life of the garment. Whether you're escaping for a weekend of bothy-hopping or moving fast from hut to hut, the new Flux Pull-On has the fit, the fabric and the features to keep you comfortable and fresh.
