BJJ JUDO CO. Rashguards are perfect for various physical activities where you need a little protection. They’re comfortable enough to wear while training martial arts like Brazilian jiu-jitsu and can help prevent mat burn. When worn under your jiu-jitsu or judo gi, they can help reduce odor and staining of your gi from deodorant when compared with not wearing one. They’ll soak up sweat better than t-shirts, stay put instead of bunching up, and show off your personal style. Our Rashguards are all unisex and offer skin protection with a built-in ultraviolet protection factor of 50+ whether you’re surfing, jogging, hiking, or doing other outdoor activities. Great 4-way stretch with 82% polyester and 18% spandex. Design is made using sublimation printing. Please note: Keep rashguards away from velcro fasteners and try to avoid rough surfaces.
