Meet the Bombas Merino Wool long sleeve t-shirt. Merino is a naturally soft fiber that's guaranteed to keep you warm when it’s chilly, cool when it’s hot, and comfortable in pretty much every situation. Even better, this Merino shirts are blended with TENCEL™ Lyocell, a fiber known for its cooling, quick-drying, and smooth-against-the-skin properties. Since Bombas anticipated you’ll be layering this under everything you wear, they added a thumb hole right in the sleeve cuff. It’ll keep your sleeves from riding up your arm, plus it’s just a fun little pop of color. This shirt was only worn a few times and is in great condition! Size: Medium Measurements: See photos, especially as this is a regular length!!! Made of: 50% Merino Wool 50% Tencel Lyocell
