The Arcteryx Proton LT Jacket is a lightweight highly breathable insulating jacket perfect as a midlayer when doing aerobic activities in cold conditions. Providing the insulation throughout the jacket is lightweight Coreloft Continuous 65 which has an excellent warmth to weight ratio as well as maintaining excellent insulating properties when damp. The outer fabric is highly breathable Fortius Air 40 fabric which also has a DWR coating to provide weather protection if you don't need a shell on over the top.
The zip on the Proton is a No Slip Zip which is works like a series of speed bumps down the zip so it doesn't slide down throughout the day, even when not fully zipped up. It has a trim fit making it ideal as a midlayer under a shell and the high collar provides necessary protection around the neck. There are 2 hand and a chest pockets, as well as dual hem adjusters to keep the warmth in.
