Product details:

This advanced women's jacket from The North Face will be your trusty companion for skiing, ice climbing, and mountaineering missions. Muscle contractions produce large amounts of heat, which can be stifling when your skin is covered and will quickly lead to you having to stop and vent out heat. The Ventrix Jacket uses synthetic insulation with unique laser-cut slits that will open when you're moving around but will close whenever you stop, which means you'll be cool when you're exerting yourself but warm when you're taking a break.
