Patriot 4.0 Thermal Pants – High-Performance Base Layer

The Patriot 4.0 Thermal Pants are crafted for athletes and winter sports lovers who demand gear that works as hard as they do. These 3/4 base-layer bottoms combine insulation, breathability, and flexibility. Whether worn under ski pants in the Polish mountains or for cold trail running, they help regulate your body temperature and reduce fatigue.

Advanced Energy Accumulator 4.0 Technology

These thermal bottoms incorporate X-Bionic’s Energy Accumulator 4.0 system—optimized to capture and retain body heat while maintaining airflow. Targeted insulation zones deliver extra warmth where it’s needed most, while ventilation structures let moisture escape efficiently. This balance ensures dry comfort even during high perspiration.

Fit, Fabric & Ergonomics

The design of the Patriot 4.0 Thermal Pants features ergonomically placed stretch zones to follow the natural movements of hips, knees, and strides. The 3/4 length keeps calves uncovered to prevent overheating while offering core warmth. Flatlock seams reduce chafing, and the material blend provides durability and a snug but comfortable fit.

Why Choose These Thermal Underwear Pants?

• Advanced insulation with Energy Accumulator 4.0

How to Use & Layering Tips

Wear the Patriot 4.0 Thermal Pants beneath your ski or snowboard outer layer for maximum warmth without bulk. They work great under shorts or lightweight shells during aerobic winter activity. Wash cold, avoid fabric softeners, and air dry to preserve performance features.
