Men’s ARK Polark™ swimrun suit

ARK POLARK™ Swimrun Suit

The ARK POLARK™ Swimrun Suit is built for the days when the water gets colder, the swims get longer and staying warm changes everything.

At the heart of POLARK™ is a soft brushed thermal fleece lining, strategically placed where warmth matters most: across the chest, back, seat and back of the thighs.

Hard tested

During One Water Race, we put POLARK™ through one of the toughest tests we could imagine. One of our swims lasted almost three continuous hours in water averaging around 17°C.

We came out of the water still warm.

That was a big moment for us. POLARK™ did exactly what we designed it to do: retain body heat through prolonged exposure to cold water while still allowing us to run efficiently once we reached land.

The suit is the foundation of the complete POLARK™ cold-water system and can be combined with POLARK Arm Sleeves, Leg Sleeves, Hood, Gloves and Socks to adapt your thermal protection to the conditions.

Because POLARK™ isn’t about simply adding more neoprene or insulation.

It’s about putting warmth where it actually matters, without taking away what makes a swimrun suit fast and functional on land.

Serious warmth, still made to run.
