For warm-weather biking or as a good first layer, our Men's Merino Ultralite Mountain Bike Short Sleeve Tee is purpose-built for the avid rider. It's super light and super soft, and its blend of ZQ-certified Merino wool with polyester will help with odor control, temperature regulation, and dry times. Plus, it offers thoughtful design elements like offset shoulder and side seams, a longer back hem, and reflective elements for low-light conditions. For your next ride, make this tee part of your go-to gear.
