The Palm NeoFlex Longsleeve is a lightweight 0.5 mm neoprene top with a soft thermal lining for comfort on or in the water. Made from limestone neoprene with a recycled face fabric, it delivers flexible performance with a simple, low bulk feel that enhances connection with the water. Ideal as a stand alone layer in milder conditions or under a shell when it is cooler, it balances warmth and stretch for all day wear.
