The Essential Jacket.

The men's Atom LT jacket has the warmth for year-round cycling commutes while also wearing perfectly as an alpine mid-layer. It's padded with Coreloft 60 insulation, which is lightweight, compressible, and warm. Polartec Power Stretch side panels with Hardface Technology gives the jacket flexible strength and breathability. The durable wind-resistant face fabric, coated with a DWR finish, provides excellent air permeability. It comes in a trim hip-length fit, and articulated elbows and gusseted underarms make its overall fit shorter, highly mobile, and mid-layer friendly. The full front zipper closes the insulated collar and has No Slip Zip to prevent self-opening. A breeze-blocking wind flap backs the zipper. The lower hem is laminated and drawcord-adjustable against cold drafts. This jacket compresses into one of its zippered pockets, making it perfect for travels and commutes where space is tight.
