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.
How to measure.
Chest: Measure the full circumference of your chest just below your armpits.
Waist: Find the top of your hip and measure the full circumference around your body.
Arm length: Measure horizontally from the centre of your back, across the shoulder, over a naturally bent elbow and down to the wrist fold.
While all our garments are sized to these measurements, you will find that the cut on jackets designed for use in more extreme environments will be slightly more generous in the expectation that these designs will be used with additional/thicker midlayers. If you plan on using a jacket like this with fewer layers beneath it, please keep this in mind when selecting your size.
All garments are designed and fitted to suit their intended end use. See below for a general description of our fit categories:
Regular: Neither slim nor loose. Regular fit items are the perfect balance of form fit and ease of movement.
Slim: A streamlined silhouette. Cut trim following the contours of the body. Expertly placed articulation of seams and the use of stretch fabric ensure maximum freedom of movement in these close-fitting items.
Relaxed: Our more generous fit. Cut loosely through the body allowing for ease of movement and additional layering.
Expedition: Designed specifically to accommodate the layering system and equipment required for high altitude and polar expeditions.
