The Ascendor Pull-On’s body mapped construction is designed to adapt more efficiently to your output and the conditions. A midweight, grid backed fleece is zoned to the torso, hips, shoulders, and upper arms and a lighter weight, micro grid backed fleece covers the centre hood, under and lower arms, and centre back. These two fabrics work differently, wicking, breathing, and drying more quickly in the high heat areas. When you’re working hard swinging ice tools, ascending steep slopes, or moving fast, theAscendor is designed to regulate your temperature and keep you comfortable. So, you can keep moving, make progress without stops, and enjoy every minute.It has a soft collar and deep, half-length zip for effective ventilation. Stretchy and slim fitting, it’s comfortable under other gear and fits easily under a harness with a longer length at the back to cover the hips. Low bulk and packable, it’s a dynamic layer suited to high energy ascents.Details Fit: Slim Centre back length: (Size M): 71.5cm / 28.1inch Weight: 284g/10oz (Size M) Body mapped fabric positioning to better regulate body temperature, optimally positioned for use as a midlayer Soft Thermic™ G fleece over front torso, hips, shoulders & upper arms Lightweight Thermic™ G grid fleece over centre hood, lower arms and centre back for better temperature regulation Half length YKK® VISLON® centre front zip with fleece lined chin guard for comfort 1 YKK® zipped mesh lined chest pocket with lightweight zip pull Flatlocked seams throughout for improved comfort Elasticated binding at the cuffs and hem for fit and comfort Dropped hem improves warmth on lower back Main: 92% Recycled Polyester, 8% Elastane.
