ARK UTO WOMEN 2026

What's new 2026 ?

ARK have carefully analyzed and refined the details to elevate the suit even further.

• Improved materials. Latest most premium Yamamoto neoprene and updated foam inserts.
• Updated inner liners, with each panel adjusted to achieve maximum performance
• Modified collar for a better seal
• New look 

ARK's most innovative race suit to date, developed in close collaboration with the world’s leading swimrun athletes. The less insulated UTÖ™ is made for warm to cool climates, offering our best engineered functionality- to-weight ratio. At only 485 grams—and our most flexible Running++ bottoms—most fast athletes opt for UTÖ™.

It’s their least constricting suit, for unyielding crawlers and accomplished sprinters looking to push the boundaries—and former speed records.

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.

Back Pocket with Flap Closure
Increased space to store race essentials such as gels and nutrition to boost speed and power throughout the race.

Separate Arm Sleeves Included
A brilliant layering option for extra warmth in cold conditions—and extra ventilation for longer running sections.  

Weight: 485 g (men’s size M)
