Worn as either a heavyweight baselayer or insulating mid-layer, our Power Stretch Pull-On is perfect for cooler conditions. From mountaineering to hill walking the Power Stretch Pro is extremely versatile. Maximising performance and comfort, it has an excellent warmth to weight ratio making it an obvious choice for long trips and cold expeditions. Designed using Polartec Power Stretch Pro, this mid-layer has four-way stretch giving you complete freedom to move, whilst the fast wicking fabric works hard to both insulate and manage moisture.
