Kuiu Peloton 118 Long Sleeve Crew T-Shirt Size - XL Color - Valo I have two of these shirts. I wore them last Fall for the hunts. They are used but don't show much sign of wear. From the Kuiu website: Unparalleled dry times and durability make this synthetic base layer ideal as the foundation of your cold-weather layering system or as a stand-alone shirt in the heat. At KUIU we believe stretch without elastane (e.g. Spandex) is critical to performance and fit. Constructed with Toray's patented Primeflex spiral yarn, the Peloton 118 delivers the durability you expect from a synthetic, while still providing great stretch and recovery without elastane fibers. Elastane or spandex fabrics are heavy, hold moisture, and lose shape over time. Our focus has been to partner with innovative fabric manufacturers such as Toray to offer fabrics that stretch through advanced fabric engineering, not the addition of elastomers. This lightweight hydrophobic 118 weight fabric wicks moisture away from your skin so it can quickly evaporate, keeping you dry and comfortable in the mountains. Toray's Makspec odor control treatment helps block odor-causing bacteria from penetrating the fabric, allowing for extended wear.
