Product details:

With intelligent ventilation, the Women's 150 Zone LS Crewe provides year round support and control, whether trekking cross country or heading out to the trails for a nimble post work run. Not only famous for its insulation properties, the BodyfitZONE construction fully ventilates the torso and arms while fully managing moisture for composed, comfortable performance in any activity. The Zone technology features merino fibers for an ulta-soft, warming feel, with each individual fiber wrapped in nylon and LYCRA for stretch, durability and mobility. Plus, because it was made in the mountains rather than in a petrochemical laboratory, this Merino wool fiber is naturally renewable, recyclable and biodegradable* (*wool tops, under certain conditions). Underarm gussets and a raglan sleeve design also increase the range of motion, while flatlock stitching prevents chafing on dynamic pursuits.
