Both the stretch weave shell and Primaloft insulation of this jacket are water-resistant to offer warmth and protection against the elements with no bulky feel. Great on its own in milder weather or worn beneath a parka as an added barrier against the cold winter, it's lined with our exclusive Nobis Tech membrane lamination to keep wind and water out and comes with an interior stowaway pocket at the back you can also use to stash extra gloves and snacks.
