The Mountain Hardwear Men's Stretchdown Hooded Jacket is a down insulated jacket for cold weather trails and reaching the summit. Above the treeline, the weather changes fast and with this movement-friendly option, you'll stay warm without slowing. The 700-fill power down is RDS-certified, is breathable when you're pushing hard and packs down easily went not being worn. Pair it with a shell when the rain or snow falls or use it alone in dry weather.
