Solid Lycra Euro Brief Fully Front and Back Lined Polyester Drawstring closure Our solids come in many colors and many styles. Lycra is knitted 80% polyester, 20% Spandex, 200 grams per square meter. Spandex is the generic name for Lycra, which is our most popular swimsuit fabric. Lycra is sleek and smooth to the touch, with maximum stretch for a comfortable fit. The Euro Brief is a smaller cut (narrower on the sides) than our regular Brief. This suit is perfect for workouts and swim meets. Fully front and back lined means that this item comes fully front and back lined; the entire front panel and the back area are lined. AgonSwim products are made to order. This means we have to manufacture your product before we ship it to you. This process takes 2 to 3 weeks.
