What makes them special?
Mono Air Pants is the latest addition to our award winning Mono Air insulation series, an innovation both in terms of performance and sustainability. The Mono Air fabric is specifically designed to combat plastic waste. It sheds 80% less microfibers compared to conventional fleece and is made from recycled and recyclable materials. Mono Air Pants is a technical garment designed with a hard face treatment for durability and water repellency.
How does it work?
With conventional fleece, the cut-off fibers that create the fuzzy structure are exposed and can therefore shed from the garment during wash or when you use it. In Mono Air, endlessly long and lofty fibers are knitted into small pockets between face and backing fabric. The pockets trap warm air from your body to create insulation and at the same time protect the insulating fibers from escaping. The face of the fabric is reinforced with a hardface treatment that prevents pilling and snagging. The result is a smooth and strong fabric that will keep you warm and endure years of hard use.
When should I use them?
The Mono Air Pants is a lightweight insulation garment for 4-season use. These light, stretchy and durable pants are mainly designed as an outer layer, but will also work as a thermal layer underneath a pair of shell pants. The knitted face fabric takes the edge of the wind but is still highly breathable. Mono Air Pants are designed to be versatile, fit for both demanding adventure and to provide comfort after or before your activities.
Please don’t throw this garment away when it’s worn out. Mono Air Pants are made from recycled and recyclable fibers. The raw materials are valuable and can be used again. Bring it back to a Houdini shop or one of our retailers that has a Houdini recycling unit.
