The warmest and most technical style of the line was quite obviously named after the iconic Grand Tetons. The shell fabric is reinforced with 13% Kevlar and it's made with baffle construction (see sketch) to prevent any cold spot. This construction also makes it extremely light compared to most competition. Try it on!
