It's made for moving fast in the mountains or clipping into your climbing harness, and not hanging out at camp in cold weather.The hood is form-fitting but not too tight so you can get a helmet on underneath, and the cut is tapered but not too constricting. The fabric features Grid technology that allows moisture to easily vent from the cracks between the islands of insulation. This, in addition to the pockets, offers some level of ventilation, making it a perfect pick for aerobic sports.It's made using Rab's Thermic Stretch fleece, a mid-weight, super-stretchy, comfortable and quick-drying material which will last for years and is as easy as a cotton t-shirt to take care of.
