If we tied all the arms and legs of the mid and base layers we reviewed this season together, you'd be able to climb down from the chair of the highest ski lift in North America... in other words, there's A LOT to see here, folks (don't forget to click through to page 2).

From the classic merino wool base layer standbys to the hybrid insulated pieces, long johns have come a long way. And whether your laying strategy involves a base, a mid and a shell, an insulated jacket that vents down to as many layers as you can fit underneath it, or a clever vest that can go in- or outside the main jacket, this season's next-to-skin comfort still sports the ultimate in performance that won't disappoint.
