Red Men’s Long Sleeve Alter Evo Waterproof Changing Robe – Siren Red

The Red Alter Evo is designed for those who won’t settle for anything less than top performance and standout style. Engineered with a 15k waterproof and 8k breathable recycled outer shell, this long sleeve robe keeps you protected from the elements while ensuring comfort before, during and after your swim or outdoor activity.

A soft Sherpa fleece lining locks in warmth while wicking away moisture, and practical details such as a peaked hood, roll-down cuffs, side stretch panels and a ventilated hem ensure full mobility and comfort in all conditions.

The Siren Red colourway is bold and eye-catching — a fiery chilli-pepper shade complemented by sleek black trim. Perfect for swimmers, paddle boarders and outdoor adventurers who like their kit to perform as well as it stands out.
