The highly popular triple collaboration between Teton Bros., STRIDE Lab, and Sakaiya Sports, which has been a great success every year. Last year's special edition of the Wind River Hoodie, the "Wind River SL," sold out immediately. This year, it's available in two colors: "Dark Navy" and "Bronze"! The base Wind River Hoodie is already a well-designed product, so there weren't any weak points to address. However, since this is a collaboration between STRIDE Lab and Sakaiya Sports, we incorporated our own requests down to the smallest details. The most noticeable change is the drawcord at the hem. The original model had elastic piping that cinched at the waist, but the Wind River SL features a drawcord, reducing hem lift and allowing for finer adjustments. The hood and sleeve cuffs have also been updated, switching from thick elastic to thinner gathers, which reduces sweat retention and creates a cleaner look. The logo on the left chest has been changed to a simple yet bold mountain lion face. Of course, it also features a double zipper. The main fabric uses "Pertex Quantum Air," which minimizes stuffiness and offers a smooth, comfortable feel that doesn't cling to the body even when you sweat. We highly recommend this model for seamless use in everyday life, running, trail running, and trekking! Please experience it for yourself!
