Constructed without side seams to minimise chafing, this T-shirt is the ideal undergarment for layering on colder days. It can also be comfortably worn on its own in warmer weather. The seamless construction makes it extra ergonomic for activities that require lots of upper body movement, like reaching for your next bouldering hold or hoisting a sail. The blend of Merino wool and stretch nylon provides breathability for sunny days on the water and excellent heat regulation to contend with chilly heights. The Seamless Merino 2 T-shirt for men is a versatile base layer for any season.
