    Customers say
    Customers say this thermal rashguard is a game-changer for cold water swimming. It provides excellent warmth and comfort, allowing users to extend their swim time in chilly conditions. The soft, fuzzy interior is praised for its coziness. While the snug fit is appreciated for its insulating properties, many advise sizing up as it runs small. Users love its versatility for various water activities, from lap swimming to snorkeling. The quick-drying fabric and ease of movement are highlighted positives. Some find it challenging to remove when wet, but overall, it's highly recommended for its effectiveness in maintaining body heat in cold water.

      Soft, comfortable

      Very pleased with this purchase. Soft, warm, comfortable. Makes it easier to get into the water and endure that initial chill. Does not completely protect from the first chill, but does reduce the chill on first contact with the water. The water temperature no longer makes me hesitate to go for my daily morning swim. I needed this insulating rashguard to stay committed to my morning fitness swim at the gym.

      I can't wait to try it out today, but I trust the brand and it was at the right price point.

      Keeps me warm

      This is the second one I have purchased, and now five more people in my Water Aerobics class have purchased them as well, based on my recommendation. We all love them!
