Technical information


This fleece sweatshirt has a loose cut. We recommend you wear a technical undergarment, in direct contact with the skin, to be better protected from the cold. It has also been designed to be worn just underneath our windproof/waterproof jackets like the women’s MH100.
Choose your usual size.

How does the material provide insulation from the cold?

The fleece component is designed to trap air in the space formed by its texture (qualified as "brushed fleece” when it is made of pile fabric); this air acts as a natural insulator, keeping the body warm.


2 types of tests are carried out to measure the warmth level of our fleeces:
- a material test
- a test on a thermal dummy in a thermal chamber. Here, we reproduce the temperature, wind (5 km/h) and humidity conditions you encounter in the mountains during a 5 km/h walk
These tests are used to validate our design choices, and everything is then validated by field testers.
This fleece has a comfort temperature between 7 and 10°C (without a jacket on top).

Product design: our expertise

Our Quechua global design centre is based in Passy, at the foot of Mont-Blanc in Haute-Savoie.
This location makes it a real meeting place for our teams (designers, product managers, engineers, etc) and outdoor sports enthusiasts.
A great asset for designing quality products for your mountain hikes, and providing you with all our expertise.
