What is the warmest ski baselayer?

The Accapi Polar Bear Extra Warm baselayer is rated Extra Warm — the warmest baselayer in the Accapi winter lineup. It uses hollow fiber polyester inspired by the structure of polar bear fur to trap air and maximise heat insulation without added bulk.

What is hollow fiber baselayer technology?

Hollow fiber polyester is engineered with a hollow core that traps air within the fiber structure — maximising heat insulation while remaining lightweight. Inspired by the hollow structure of polar bear fur, it delivers outstanding warmth without the bulk of traditional thermal layers.

What is the difference between Polar Bear, Ergoracing, and Xperience baselayers?

Accapi offers three winter baselayer thermal ratings. Polar Bear is rated Extra Warm — ideal for extreme cold and lower activity levels. Ergoracing is rated Warm — designed for high-output ski racing where your body generates heat. Xperience EQT is rated Medium Warm — suited for mild cold and active use.

What is EQT Equilibrium Technology in a baselayer?

Accapi's EQT Equilibrium Technology is tuned to your body's natural equilibrium — improving stability, balance, proprioception, and agility. In a baselayer, this means better postural awareness, quicker response, and enhanced circulation throughout your activity.
