"Women's CW-X® Endurance Generator Insulator: The CW-X® Endurance Generator Insulator tights are built around a simple idea - give your muscles and joints the support they need so you can keep moving longer. The patented EXO-WEB support panel is biomechanically placed to contour around your hip flexors, quads, hamstrings, calves, and hip and knee joints, combining compression with the targeted support principles of kinesiology tape. The result is stability through your full range of motion without feeling restricted, which makes these women's compression tights a strong choice for high-endurance training runs, long races, or any activity where your legs are working hard for extended periods.The EXO-WEB panel uses 2-way stretch construction to move with you rather than against you, while the multi-directional EXO-stretch body fabric keeps the fit consistent mile after mile. Lower back and abdominal panels add core support where many tights fall short. The breathable, moisture-wicking fabric helps keep you dry during hard efforts, and flat seam construction reduces chafing on longer outings. A reinforced elastic waist with an interior flat drawstring lets you dial in the fit, and a small internal waistband pocket handles the essentials - a key, a gel, or a card. Reflective CW-X branding and UV protection round out the details. The fabric is 80% polyester and 20% spandex.Why Our Fit Experts Love It""I recommend these to runners who are logging serious miles and want more than basic compression. The EXO-WEB panel is something you actually notice - your legs feel supported through the hips and knees in a way that standard tights just don't offer. The waistband stays put, and the pocket is small but genuinely useful on a long run."" - Rachel, Road Runner Sports Fit Expert, Carlsbad, CAWho It's Best ForThese tights are a strong match for women who run long distances and want targeted muscle and joint support beyond what standard compression leggings provide. If you deal with fatigue in your quads, hamstrings, or knees during extended efforts, the EXO-WEB panel addresses those areas directly. They work well for road runners, trail runners, and endurance athletes who prioritize support and stability during high-output training. The adjustable waistband and internal pocket add practical value for runners who prefer a secure, customizable fit on longer outings.
