Shoulder seasons can offer some of the most enjoyable times to climb, but they do make layering a challenge. Face the rapidly changing weather with the Mammut Men's Ultimate V SO Hooded Jacket, and you'll be ready to work hard when the chilly wind interrupts your otherwise-serene bouldering sesh. This softshell has Gore Windstopper to keep the gusts at bay, and a DWR coating to protect you from any light precipitation that may blow in with those gusts. The polyester lining sits softly against your skin, and has a finish to help it wick away any perspiration it encounters—reducing post-crux chills.
