Versatility is the name of the game with this 1/4 zip. Named for Mount Isolation—one of New Hampshire's 48 peaks over 4,000 feet that stands alone at the southern end of the Presidential Range—this midweight layer provides the warmth and insulation you need when battling the cold. Zip up to use the mock neck when temperatures drop, or unzip to vent when you're working hard. The 100% merino wool construction wicks moisture, regulates temperature, and resists odor whether you're wearing it as a base layer, mid layer, or on its own. Take it on your next outing and you'll soon find you won't leave home without it.

- Yoked shoulders offset seams for comfortable backpack fit
