The sleeveless version of our top tier suit UTÖ™, offering high ventilation on hot running sections along with superb freedom of movement in the shoulder area when swimming. UTÖ™was developed in close collaboration with the world’s leading swimrun athletes and the first UTÖ™ AIR prototype was tested during the 2021 ÖTILLÖ Swimrun World Championships. The result? Oh, you know, a new World Record time. No biggie. We’re getting used to them.
TECHNOLOGIES
Premium Yamamoto LIMESTONE Neoprene
Super smooth, durable and insulating material, beating any other option on the market. Holds up over time, without brittle cracks that risk letting water in.
Anti-leak Construction
A second skin that completely seals out any cold water trying to seep through the material and down your neck or arms.
GlideSkin Coating
Designed to decrease friction, making you smoother and faster in the water.
Shaping Power Fabric with Water-Repellent Coating
Thin yet highly functional compression materials that contribute to low weight, high performance and no constrictions.
FOAM+ Master Buoyancy Belt
A lightweight option helping your core with some extra flotation, necessary to retain speed and energy when swimming with trail running shoes.
Running++ Bottoms
Our game-changing, stretchy bottoms—evolved. Made with a shaping power fabric and water repellent coating, for race courses where full sprint is the only way to get ahead.
UltraFlex Inner Liner
Prevents chafing and provides pleasant freedom of movement instead of constricting your thigh muscles when fighting lactic acid on the last sprint to the finish line.
Smooth Neck/Collar with Pressed Edge
Keeps chafing to an absolute minimum, while improving the durability of the suit as a whole. Comes in handy for the runner that likes cabbing down on longer trail sections.
