Protect your skin with O’Neill’s premium quality lycra rashguards! These rashguards are the perfect combination of quality, refined fit, and price. All seams are flatlock stitched for optimum durability and comfort (non-chaffing seams.) The lycra (a nylon/spandex blended material) is naturally anti-microbial and is breathable to be comfortable in even the hottest conditions. While being breathable, the rashguards still blocks over 99% of harmful UV rays. All rashguards in O’Neill’s line feature ergonomic seam placement and 4-way stretch lycra for a perfect fit and feel. This rashguard model fits tight for high performance activities. If a looser fit is preferred, purchase one size larger.
