Tracksmith Waffle Knit Base Layer

Tracksmith Men’s Fells Waffle Layer 100% Merino Wool Waffle Knit Base Layer sold out on the Tracksmith website The waffle pattern on this base layer traps air against the skin to increase insulation, while also allowing heat to escape as the effort increases. Excellent quality and in great shape, but I unfortunately outgrew it. There is one small pinhole (pictured), but you can’t see it when wearing the shirt and the waffle knit pattern means it won’t get any bigger.
