If you favour the fit, reliability and easy-vent warmth of a half-zip fleece, our lightweight Filament Pull-On is a fast-wicking technical midlayer that is purpose-built for active mountain use.
The Filament Pull-On is built from the latest recycled Thermic™ fabric - a stripe-patterned technical polyester fleece with 7% elastane for unrestricted movement when climbing, trekking and skiing. The fabric is also inherently hydrophobic, enabling it to retain its thermal efficiency in wet conditions, while shifting moisture rapidly through the layers and away from the body. Soft, lightweight and breathable, the Filament Pull-On comes with a half-length zip, an elevated collar and discreet thumb loops to keep the sleeves secure and draught-free when you up the pace. It also features a secure YKK® zipped chest pocket and smooth flatlock seams for increased comfort.
Whether you want to use it as a simple everyday warmth boost or as a high-energy, cold-weather mountain midlayer, the Filament Pull-On is 268g very well invested.
