"Men's Korsa® Fuse Base Layer Tight: When the temperature drops and you still need to get your miles in, the Fuse Base Layer Tight gives you a full-length compression option that moves with you rather than against you. These men's cold weather tights are built to wear alone on milder days or layered under track pants when conditions get serious. The body-hugging fit stretches easily through each stride, so you stay comfortable whether you're warming up or pushing through a longer effort in the cold.The 71% polyester/29% spandex fabric keeps the fit close without feeling restrictive. Soft high gauge knit compression panels at the calves support the muscles and help with recovery, so your legs feel better mile after mile. The flat-lay exposed waistband sits comfortably without bunching or gathering, and an internal drawcord lets you dial in the fit. Reflective stripes across the calves add visibility during low-light runs and early morning training. The size medium inseam measures 28 inches for a full-length coverage fit.Why Our Fit Experts Love It""I reach for these on cold mornings when I know I'll be out for a while. The calf compression actually makes a noticeable difference on longer runs - my legs feel less fatigued by the end. I also like that the waistband stays put without needing to adjust it mid-run."" - Dave, Road Runner Sports Fit Expert, San Diego, CAWho It's Best ForThe Fuse Base Layer Tight is a strong choice for men who run through fall and winter and want a full-length tight that works as a standalone layer or under a looser pant.
