Under Armour 1303112-923 Smart Cold Weather Breathable Warm Hooded Mountain Jacket: ColdGear Reactor technology adapts to activity level
For the active hiker or winter commuter who needs reliable warmth without bulk, this Under Armour jacket adapts to your day. While many cold weather jackets focus on insulation alone, this one balances breathable warmth with smart mobility—so you stay comfortable from trailhead to office.
The ColdGear Reactor technology adjusts to your activity level, providing cozy insulation during rest and breathable warmth when you move. The unique quilting pattern and lightweight design ensure it moves with you, not against you. Pack it into its pouch after your hike, and the magnetic zipper makes one-handed adjustments easy. Note: the waist area fits snugly compared to the rest, offering a form-fitting feel that minimizes bulk.
