O'Neill Thermo-X L/S Crew

O’Neill Thermo-X Vest long sleeve thermal top is a warm, quick-drying layer designed for water sports. It is made from water-repellent polyester fabric and works perfectly as an additional insulating layer in colder conditions, especially when worn under a wetsuit.

Thermal Top Helps Maintain Body Temperature

The O’Neill Crew men’s long sleeve thermal top is designed to help retain body heat during water sports. While it does not provide the same level of insulation as neoprene, the difference between wearing a thermal top and a standard UV rash vest is very noticeable.

Despite being lightweight and compact, the Thermo-X Vest offers excellent insulation. The fabric dries quickly and helps prevent unpleasant odors, making it comfortable to wear for extended sessions on the water.

Wear the Thermal Top Under a Wetsuit

If you feel cold while SUP paddling, kitesurfing, or windsurfing, wearing this thermal top under your wetsuit provides an extra layer of insulation. It also helps prevent chafing by creating a smooth layer between your skin and the wetsuit seams that may rub during movement.

Thermal Top with High-Quality UV Protection

The top can also be worn on its own, as it provides reliable UV protection. The material used in the O’Neill Crew thermal top has been recommended by the Skin Cancer Foundation as an effective form of UV protection.

Thermal Top Details

The low-cut collar is designed to sit comfortably under a wetsuit without bunching or folding, helping to prevent irritation and unwanted water entry. A small loop at the front hem allows the top to be attached to wetsuit bottoms, preventing it from riding up during falls.
