Women's Siren Long-Sleeve Mock-Neck Shirt

The Women's Siren Long-Sleeve Mock shirt has all the features of our original Barrier line, with a few new tricks up its water-resistant sleeves. Featuring seamless underarms, a woman-specific fit, four-way stretch, water-repellent fabric, flat-lock seams, and 50+ UPF protection. This updated Siren line also features banded cuffs for a snug seal at your wrists, contrast-color side gussets, and a new back zipper to allow heat release and easier removal.   MATERIALS ATMOS 1.0 Featured in SeasonFive's watersports apparel is our proprietary Atmos 1.0, engineered to block outside elements including wind, water, and harmful UV rays, while still allowing vapor and heat to escape. This fabric blend was developed with muscle supporting stretch and minimal seams to ensure you stay more comfortable, longer.
