The 100% Merino Bart T is a genuine do-it-all star of your wardrobe. Superfine Merino is the absolute best against your skin and will be the base garment of choice no matter what you are doing. Cut like a slim fit T shirt, the Bart has generous length making it ideal for outdoor activities (like, say, bike riding) where you want to keep your back covered, and is also very styley with your jeans as a general purpose T shirt that will perform like a champ. May shrink 3 - 4 %, machine washable but best not tumble dry.
