Retain more heat with the Mountain Hardware Stretch Down Jacket. Winter may not be top of mind, but it’s never to late to start the prep. When it’s below zero, even a fraction of heat retention is worth every penny. New for this season is Mountain Hardware’s new stretch-welded channel construction which traps more heat than the traditional stitching techniques. Crafted from Dynamic-stretch knit and insulated with Nikway Hydrophobic 800-fill RDS Down, featuring smart dual-sided hem adjustments, zipped hand warmer pockets and a two easy access interior pockets. Other than the main zipper, this new welded channel construction gives the cool air very little room to penetrate, allowing for longer heat retention.
