A sturdy warming liner glove with Primaloft Gold synthetic insulation that keeps hands warm in severe cold. Combines with a shell glove, such as Hestra’s Seam Sealed Mitt or Pull Over Mitt. Also practical as an extra liner, e.g. for the Army Leather Expedition Mitt, if you want to be able to swap liners over the course of the day. Primaloft Gold produces a down-like feel and binds a lot of insulating air while letting moisture escape.
