There's a reason why people swear by merino. The fabric dries quickly and its temperature regulating characteristics makes it ideal for both cool and warm weather. Outlier's own recipe mixes merino, cotton, and nylon for a shirt that's got the feel of a heavyweight tee, but with the technical benefits of merino. Their latest edition of the shirt teams the company up with Buaisou in Tokushima, Japan. Buaisou farms their own indigo and has dipped Outlier's tees using their natural dying process. Better move quick if you want to grab one, this is an experimental edition so they're pretty limited and quite pricey.
