The Sabre AR is the allrounder, middle weight whiteline jacket from Arc'teryx. It features the same snow sport specific features across all whiteline jackets, with plenty of room for layering for all types of conditions. The ultra fine soft brushed interior gives this jacket a slight edge against the cold and improved next to skin feel.
In this video I'm wearing a size medium (usually size large) and you can see at 4:48 that range of motion is not impeded. However it takes away the ability for heavy layering for the coldest of conditions.
