Base Layer Basics. The Easy Fit Light Cushion Crew is a bit softer and not quite as snug as the original fit. Ideal for folks with wider feet, in-between sizes, or who are looking for a little more volume due to sensitivity. A balanced base layer with a lightweight profile, strategically-placed LIGHT cushioning zones, and the ‘custom-fit-feel’ of Fits' patented ‘Y-Line’ knitting structures. While it's called a light hiker, it’s remarkably versatile, comfortable, and loved for all sorts of wearing occasions.
