Fourth Element Men's Long Sleeve Hydro-T Black/Ocean blue

Part of our OceanPositive Collection, these new Hydro-T rashguards are designed to be worn under a wetsuit or semi-dry suit or as a UV shield for all water sport activities.

Flatlocked seams give greater next to skin comfort, and the SPF 50+ fabric ensures that you are protected from the harshest of the sun’s rays whatever your choice of watersport.

The ultra smooth fabric made with a combination of recycled polyester and stretchy elastane reduces friction between the skin and a wetsuit and helps to stop chafing from tight/ill-fitting suits.

A handy pocket incorporated into the side panel is sized for a phone, and particularly useful when paired with swimwear.
