ONeill Thermo- X Short Sleeve Top

The O'Neill Thermo-X Short Sleeve Top is designed to add warmth without adding a lot of bulk. It is a smart piece for riders who already have a wetsuit they like, but want to stretch it further into colder conditions or longer sessions.

Thermo-X pieces are layering products rather than standalone cold-water replacements for a full wetsuit. They are there to give you a noticeable warmth boost without making everything feel bulky.

Why we recommend it

• Adds noticeable warmth without the jump to a much thicker wetsuit.
• Low-bulk layering makes it easier to fine-tune your setup around the season and session length.
• Quick-drying thermal fabric is a practical option for paddlers, surfers and wingfoilers in cool conditions.
• A useful way to extend the range of the wetsuit you already own.
