Columbia Mountain Mobility Sweater

$190; columbia.com

The lightest jacket (20 ounces) reviewed here, the MMS is the perfect choice for bashing spring bumps or ski touring. Need more cold weather versatility? Zip it into one of Columbia’s stormproof Titanium hard shells. You’ll need that shell, because the MMS is made of the same stretchy, but not stormproofing, stuff as the Cloudveil-just without the liner. Smart design: The front pockets are the perfect size for climbing skins.
