Castelli

Perhaps the best natural fiber out there, wool is as timeless as it is technical. Castelli's Wool Long Sleeve baselayer is made from ultra-fine Merino wool that has a cashmere-like hand and a rich softness that makes you want to wear it every day, not just while riding. It breathes incredibly well, wicks moisture to keep you dry and comfy and insulates even when wet. Whether it's cool, cold or bitter, wool has the unique property of always being the right choice.
