We have carefully analyzed and refined the details to elevate the suit even further.
The iteration of our flagship suit ORNÖ X™, an incredibly warm and buoyant suit for cold conditions and choppy waters.
We know every single gram counts when fighting lactic acid and tugging your tired buddy through the water. But so does every single second when record times are at stake, and you need maximum efficiency in transitioning to run mode, stowing away paddles and refueling on gels.
ORNÖ X™ is not only fast—it’s an absolute work horse.
Higher density, durability and insulating properties than any other option on the market. Holds up over time, without brittle cracks that risk letting water in.
Exceptional warmth-to-weight ratio, keeping your muscles warm and efficient. We’ve even laminated titanium into the chest panel, right between the inner liner and outer neoprene. It reflects your body heat and boosts the suit’s thermal properties.
A second skin that completely seals out any cold water trying to seep through the material and down your neck.
Provides your core with extra and improved flotation, necessary to retain speed and energy when swimming with trail running shoes in choppy waters.
Game-changing, stretchy bottoms, providing your muscles with maximum freedom of movement when scrambling along rocky shorelines or blazing through the woods.
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.
A brilliant layering option for extra warmth in cold conditions—and extra ventilation for longer running sections.
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.
A smart pouch to store compression bandage, nutrition or other race essentials, safely secured and easily accessible.
*** Sizing small, choose one size larger than recommended ***
