An ultralight baselayer top built with a super-soft, stretchy and highly durable merino wool blend, the Anatomica Long Sleeve Crewe provides the versatile, breathable insulation you need for cool-weather pursuits and daily comfort. With an updated fit that makes it even more comfortable, the Anatomica Long Sleeve Crewe also feature our corespun fabric, which uses nylon fibers wrapped in merino wool for increased durability and strength that retains next-to-skin softness. Flatlock seams eliminate chafing when you're on the move.
