The grid-fleece Katinka Hoody is the ideal midlayer for wearing in the mountains. Finding the right midlayer that keeps you warm (but not too hot) and layers well under a shell (not too bulky) isn’t easy. The streamlined, grid-fleece Katinka Hoody does it all well. Wear it on the climb uphill (it’s breathable), then throw a shell over the top for the way down. This fleece doubles as a great around-town piece, too. A drop tail gives you a nice long fit and there’s a perfect pocket for your phone. Furano Fleece: 94% polyester, 6% spandex Taffeta 100% polyester
