    How to measure: For the most accurate fit, measure yourself in your underwear. Use a soft measuring tape and keep it snug but not tight. For chest measurements, measure around the fullest part of your bust. For waist, measure around the narrowest part. For hips, measure around the fullest part. For sports bras, measure your underbust directly under your bust where the band sits.

    Dominate every activity in the Men's Eclipse Baselayer—leggings engineered for peak performance. The buttery-soft blend of 82% polyester and 18% spandex features four-way stretch that bounces back with you, whether you're sprinting, squatting, or stretching. A fitted cut with a front gusset delivers comfort and freedom of movement, while the elastic waistband keeps everything secure. Moisture-wicking technology pulls sweat away so you stay fresh and dry, and flatseam construction prevents chafing during intense sessions. From MMA training to morning runs to everyday adventures, these leggings are your reliable companion for looking sharp and feeling unstoppable.
