As with all our core 3.0 range, our Thermal Leggings are about blending comfort with performance technology.

These leggings are made of a thick but lightweight KYnergy Infrared fabric, which boosts the garment’s thermal qualities whilst retaining our unique material’s benefits for performance and recovery.

The leggings feature our unique seamless front to back gusset and flatlock stitching, meaning you can run free of distracting rubbing or chafes, and the elasticated waistband is secure and flexible to prevent any digging into your midsection. Together, these features make the leggings comfortable for all workouts, whether that be the most gruelling crossfit session, a light recovery run, or a mountain hike. The leggings are great worn on their own or under a pair of loose-fitting shorts.

We’ve incorporated a compressive fit into the calves of the garment to support the muscle and assist with the return of blood and any toxic byproducts of exercise back to the heart.

The leggings are made from our infrared-emitting fabric, which helps regulate your body temperature as you work out, dissipating heat and evaporating sweat better than normal fabrics, keeping your skin feeling dry no matter how hard the session. Furthermore, our unique technology increases oxygenation and glycogen storage in the blood, meaning that your legs are directly benefiting from an increased energy supply to help you train harder, for longer.

The infrared technology in the leggings’ material also assists with recovery after your session.

By keeping the garment on for four hours after your activity, the increased oxygenation of the blood will improve the rate of lactic acid breakdown and cellular repair throughout the body.

  • Increased tissue oxygenation by up to 20%
  • Increased cellular metabolism
  • Enhanced energy production
  • Pain relief
  • Accelerated recovery rate
  • Compression fit on the calves for added support and comfort
  • Seamless front and back gusset
