The Mason combines the awesomeness of our Merino Wool blend in the body with our synthetic Tri-Blend sleeves in 3/4 length for those chilly mornings or laps in the bike park. The sleeves and shoulders are made to be durable and survive the occasional off-the-bike slide or fall. We tapered the sleeve as well, so you don't need to worry about looking like a wizard while you're shredding the trails. Pull it up to your elbows on hot days and it stays where you want it.
We choose Merino wool because it wicks moisture exceptionally well keeping you dry and comfortable within a wide range of conditions. It's warm when the temps are cool and cool when the temps are high. Our merino is a special 77% Merino Wool, 18% Nylon and 5% Spandex blend giving you the perfect combo of performance, comfort and durability.
