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.
