Lightweight, waterproof and breathable membrane fabric
AIRLET is a new generation of extra-breathable laminates from the SIBERIUM family, developed by us. It comes in three constructions: 2L, 2.5L and 3L.
All variants share protection from rain, high breathability, low weight, a pleasant feel and easy care.
The membrane lamination creates a barrier against liquid water while allowing water vapour to pass away from the body.
The individual AIRLET variants differ in construction and number of layers, so the material can be used for different types of outdoor and sports activities.
How AIRLET works
Membrane barrier
The lamination creates a waterproof layer against liquid water while allowing water vapour to pass through to wick moisture away from the body.
Mechanical stretch & shape retention
The fabric construction and the fibres used provide natural mechanical stretch and help the material return to its original shape.
Pleasant feel
The specific fibre structure gives the material a soft, cotton-like touch that differs from common polyester fabrics.
Low weight & easy care
The laminate is light, packable, quick-drying and easy to care for.
BREATHABLE PERFORMANCE
Functional properties designed for active movement
Active Breathability
Efficient moisture wicking helps maintain a more comfortable microclimate even during physical exertion.
Weatherproof Confidence
Reliable protection from rain and wind in a light and easily packable design.
Soft, Cotton-Like Touch
A technical material with a pleasantly soft feel for all-day comfort.
Built-in Stretch
Mechanical stretch without added elastane supports freedom of movement and helps the material return to its shape.
Pack Light, Move Fast
Low weight and quick drying make it easy to use for sports and everyday activity.
Easy Maintenance
The material holds its shape well and is easy to care for.
One technology. Three constructions.
SIBERIUM AIRLET is available in three variants. Each construction offers a different layer solution and is designed for different requirements on weight, durability and use.

A comfortable solution for versatile use
The light two-layer laminate combines the outer fabric with the membrane and requires a separate lining.
AIRLET 2L is suitable for clothing where a combination of weather protection, high breathability and all-day comfort in motion matters.

TURNAU-U, LORIEN-W, METHONE-M, EURINA-W

Low weight when every gram counts
In the 2.5-layer construction, the membrane is protected on the inside by a light protective print.
The material therefore does not need a full inner layer and keeps its low weight and high packability.

HURRICANE-M, HURRICANE-W, ALPIN-M, ALPIN-W

Maximum performance for demanding conditions
The three-layer construction combines the outer fabric, the membrane and a full inner protective layer into one unit.
The result is higher durability, more stable performance and a long service life of the material even with frequent wear and washing.
