Timeless, colorful, and sustainably produced – the HILLCLIMB SHIRT W brings style and function to your outdoor wardrobe. As a classic Martini Sportswear T-shirt, it's a perfect basic for virtually any adventure in nature. Its lightweight, stretchy material is breathable, moisture-wicking, and odor-inhibiting, leaving you feeling pleasantly fresh even after hours on the trail or hiking trail. It feels like cotton to the touch, but the fabric is actually made from 95% recycled polyester – good for you, good for the environment.
