The Kangaroo Thermal Top™ was created after long-term feedback from our athletes, especially those who find the cold more adventurous.

We designed the Kangaroo Thermal Top™ for you to wear under your ARK suit, either the swimrun suit or the GOAT™, but you can also use it separately when running. With 4 separate pockets you can also bring energy, a phone or whatever you need on your adventures. The 

Kangaroo Thermal Top™ is very smooth and flexible which makes it breathable and comfortable even during the running sections. 

The combination of thermal properties and ventilation makes the top custom-made for swimrun or open water swimming when temperatures are low.
