It’s a tee born for breathability, and dreamed up by changing the DNA of the OG ever so slightly. It has all the moisture-wicking and anti-odor properties merino wool promises, but its mesh knit gives it an incredible level of stretch. The mesh texture also creates a lighter feel on the body, perfect for hiking, biking, HIIT training, and more. You’ve already got the original 72-Hour Merino Tee. Now it’s time to add this for your most sweat-intensive training.
