On cold winter days, treat yourself to effective thermoregulation and outstanding wearing comfort with the X-BIONIC® APANI® 4.0 MERINO PANTS MEN. The new 4.0 generation is the first to feature the Retina® ultra-high definition quality for unique accuracy of functionality. For a targeted effect, intelligent functional zones can be positioned even more precisely in the ultra dense knitted fabric. The high-performance functional underwear for ambitious winter sports enthusiasts offers the top comfort of the APANI® Merino Premium fibre for a decisive plus in performance even in extreme cold.

The legendary patented 3D Bionic Sphere® System with ThermoSyphon® technology is more powerful than ever and is active on the front and at the tailbone: 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® and the InsulationPads as well as the AirConditioningSpot und ISO-Pads, are also performance-enhancing thermoregulating technologies. The ExpansionKnee ensures optimum climate comfort and at the same time offer full freedom of movement.


Air­-Conditioning Channel®: Fresh air circulation for more performance.
The permanent air movement along the Air-Conditioning Channel® effectively draws out and removes moisture from the sweat zones.

Innerlap AirConditioning 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.

InsulationPads: Always maintain your muscle performance.
The X-BIONIC® InsulationPads assist in the retention of heat in the thighs and thus reduce the risk of injury.

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

ISO-CalfPad: Perfect insulation for your calves.
The ISO-CalfPad retains body heat. By holding body warmth in special channels, the cooling of the calf muscles is decisively delayed and contributes to the body's overall sensation of warmth.

ISO-Pads: Larger insulating surface
ISO-Pads enable targeted insulation of individual body parts from a cold environment. By retaining body heat that is necessary to guarantee interior organ functions the temperature-regulating zones prevent the cooling down of the whole body.

Air Guides®: Work like spacers and side stops along the Air-Conditioning Channels®.Work like spacers and side stops along the Air-Conditioning Channels®.

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.

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.
