DRYARN®

Dry skin. Always. Even after three hours in the saddle

Dryarn® does not absorb sweat, it expels it.
Result: no moisture on the skin, no odors, no weight. From the first kilometer to the last.

How it works

The fiber that retains nothing. Polypropylene is hydrophobic by nature: it does not absorb water, it's impossible.
Sweat is expelled within minutes. Without moisture, bacteria do not proliferate: thus zero odors, wash after wash.

What changes for you

The skin remains dry even under the jacket, even in summer, even in traffic.No bacteria, no odors. The garment returns like new with every wash.The lightest fiber in the world. You don't feel like you're wearing it.Seamless: zero friction, zero marks on the skin, even after hours in the saddle.

ØHEAT

Cool head. Even in July with a helmet on.

The hyper-perforated ØHeat fabric creates active ventilation between the skin and the helmet. The temperature remains constant. Your head stays clear. Even when it's 38 degrees outside.

How it works

The micro-perforations in the fabric create real air channels between your head and the helmet shell. Air circulates, heat dissipates, and the perceived temperature drops.

What changes for you

Constant temperature: Heat dissipates continuously. Even when you're stopped at a traffic light.Clear mind: Less accumulated heat, more concentration in the saddle.Always dry: The fabric does not retain moisture. Your forehead stays dry.For extreme heat: Designed to work even in high temperatures.

ØWIND

Wind protection. From the very first kilometre.

The ØWind three-layer fabric blocks the wind and protects the body — from head to toe.
No penetrating cold, no stiffness, no ride ruined by the wind getting in.

Three layers, one barrier.

The outer layer blocks the wind.
The middle layer insulates thanks to the internal microfleece which retains the heat your body produces and redistributes it.
The elasticated cotton insert allows breathability where the fabric presses most.

What changes for you

No wind: Your body stays protected.
The wind doesn't get through, even on the highway.Warming: The microfleece retains body heat and redistributes it. It doesn't just insulate.Freedom of movement: Flexible, it follows your riding posture without ever pulling.Three seasons: Spring, autumn, winter. Whenever wind is a problem while riding.

ØWASTE

The same technical result. 100% regenerated yarn.

ØWaste is recycled polyamide with the same technical properties as virgin fiber: thermal insulation, resistance, comfort. The same performance, with an eye on the environment.

Regeneration takes nothing away.

Recycled polyamide maintains its strength, thermal insulation, and elasticity.
The brushed interior and flat seams complete a garment that performs exactly as you expect, and you also know you are doing good for the environment.

What changes for you

Always warm: Thermal insulation like a true technical garment. Durable: Same strength as virgin fiber. Lasts longer than you expect. Comfort: Brushed interior, flat seams. You won't feel the difference on your body.

Merino Wool

In technical sportswear, merino wool garments offer exceptional performance because they act like a smart second skin. During activity, this fabric dynamically adapts to the intensity of exertion and changes in climate.

Skin always dry: Wicks away sweat as vapor before it condenses.
Stop the shivers: Prevents body cooling during breaks or when the wind drops.
Zero odors: Blocks bacteria, allowing the garment to be used for several consecutive days.
Active climate control: Cools when the body heats up and insulates when it's cold.
Anti-chafing comfort: The extra-fine fiber is super soft and does not irritate the skin.
Sun protection: Offers a very high natural shield against UV rays at altitude.
Fire safety: Does not melt or ignite with campfire sparks.
