Feel the soothing effect of lighter and at the same time highly functional high-tech underwear. With their moderate compression, the X-BIONIC ENERGIZER 4.0 PANTS 3/4 MEN fulfil all the wishes of demanding winter sports enthusiasts who want to benefit from outstanding wearing comfort and performance-optimising thermoregulation at the same time.

The new 4.0 generation is the first to feature the Retina ultra-high definition quality for unique accuracy of functionality. The result is an ultra-dense knitted fabric that integrates 13 highly effective technologies. Functional zones with temperature-compensating and protective effects are positioned precisely and support your performance on cool winter days without you feeling constricted.

The legendary patented 3D Bionic Sphere System with ThermoSyphon technology is more powerful than ever: Complex 3D structures and Y-shaped elements maximize air exchange, cool when you sweat, and warm when you are cold - now faster and more efficient than ever.

Functional zones such as the Innerlap AirConditioning Zone on the inside of the thighs and Sweat Traps for targeted handling of excess sweat regulate temperature and increase performance. The ExpansionKnee at the knee joint ensures optimum climate comfort and at the same time offers full freedom of movement.

  • ENERGIZER 4.0. Highly functional decision layer of generation 4.0. First choice for sports enthusiasts who prefer unlimited comfort, optimal thermoregulation and light compression.

  • AWARD-WINNING, PATENTED 3D BIONIC SPHERE SYSTEM WITH THERMOSYPHON TECHNOLOGY. Features complex 3D structures of inner and outer air channels. It cools when you sweat and warms when you are cold.


  • INNERLAP AIRCONDITIONING ZONE is a fine network of knitted fabric with ZERO‑Insulation Zone. Cools via air exchange as soon as sweat develops.


  • 100% PURE SWISS ENGINEERED. Made in Italy. 700+ international awards and test wins, 800+ patent registrations for the products with the "X".


Innerlap Air Conditioning Zone: Efficient cooling whatever the conditions.
Air permeability is increased in this area through the Innerlap AirConditioning Zone, the insulation layer is reduced, so air conditioning is strengthened by air exchange.

Expansion Ribs: Freedom of movement combined with high insulation.
The flexibility of the Expansion Ribs and the elasticity of the yarn allow frictionless freedom of movement without the risk of cooling down.

Air Conditioning Spot: Cools the knee without the risk of chilling.
The AirConditioningSpot cools without chilling.

3D Bionic Sphere System with ThermoSyphon Technology: Unique and extremely effective temperature management.
The patented ThermoSyphon structure adds an extra dimension to the special properties of the 3D Bionic Sphere system: Y-shaped elements support natural thermodynamics and thus improve sweat management.

Aktiv-Bund: Tighly adaptable for perfect fit
The highly elastic Aktiv-Bund provides a secure fit and support without constricting or impeding movement.

HipHolder: The HipHolder ensures that the waistband remains perfectly in position with every movement.

IDEO-Waistband: Ideally designed, ergonomically optimized.
The ideally designed, ergonomically optimised waistband, with higher cut in the back, keeps the garment in place even during constant movements.
