Outlier is taking the construction of their merino shirts one step further with a new experiment that uses ultrasonic welding. What they've done is create the first ultrasonically welded merino shirts, a process that has never been done before on merino. This reduces any bulk or threads making a streamlined tee that has flatter seams than typical construction methods. The result is a tee with almost no seams and some of the best performance fabric out there.
