Men’s ARK Utö™ AIR
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.

A second skin that completely seals out any cold water trying to seep through the material and down your neck or arms.
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.

World’s most innovative
The name Utö honors the island Utö in the Stockholm archipelago. If there is a Mecca of swimrun, Utö is the spot. This is the last island and also the finish of ÖTILLÖ Swimrun World Championships, a vision, and a dream for many swimrun athletes.
Low weight is a key in swimrun and our main topic when it comes to product development. With its 450 g (men’s M), UTÖ™ AIR is the lightest suit of its kind.
Unique material combination
UTÖ™ AIR is made of a unique material combination that makes the suit extremely lightweight and optimized for the next level of swimrun performance.
Yamamoto LIMESTONE neoprene
The upper part is made of the most flexible glide skin neoprene from Yamamoto. The neoprene gives you thermal protection and reduces drag.
A new buoyancy FOAM panel increases the floatation compared to neoprene. The result is a lighter but also more buoyant suit.
Woven stretch fabric
Leg parts are made of premium woven stretch-fabric. This is one of the fastest and most innovative fabrics available. The fabric is extremely lightweight with the lowest water absorption. Treated with long-lasting water repellent coating which reduces drag significantly.
We know that the running has a big impact in swimrun. UTÖ™ AIR is designed with optimal running properties. The hi-end fabric in leg part allows you to run with zero restrictions.

The size chart is just a guide. Since the fit is most individual you should try the suit. Our suits are flexible, if you are between two sizes we recommend you to take the smaller size.
