As comfortable alone on a fall trail run through the woods as it is under layers at the ski resort, the Aero Long Sleeve Crewe is an ultralight merino baselayer for your most active days outside. Featuring our lightest-weight merino jersey fabric blended with nylon for added durability, the Aero breathes extremely well, dries in a flash and resists odors during extended travels and long days on the go. The updated design features a feminine scoop neck and forward set side seams for added comfort. Flatlock seams prevent chafing when you’re moving fast or wearing a backpack.
90% Merino Wool, 10% Nylon
