The Mountain Hardwear Men's Hunker Down Jacket’s 50-denier outer fabric is heavier than most down jacket shells so it’s less likely to snag, rip or wear through. Fully adjustable cuffs afford plenty of extra room for gloves or mitts when needed. Durable 50 denier fabric, and plenty of lightweight down make this jacket a rugged go-to cold weather favorite. Built for maximum warmth in abusive conditions.
