Fleece material: Insulation provided by air : The mission of the fleece component is to trap air thanks to the volume created by its texture (and the brushing of the knit). This air acts as a natural insulator, keeping the body warm. This component has been laboratory-tested for a comfort temperature from 7 to 10C without any additional jacket. Durability warranty of 2 years : We test the ageing of our hiking fleeces to guarantee their durability. We guarantee: - resistance to wear from backpacks and moving arms to delay the appearance of pilling which is specific to this material - the solidity of the seams - the resistance of the fleece material after several washes - colour-fastness after washing, when exposed to UV or in contact with perspiration. DOPE-DYEING : Bulk dyeing or dope dyeing incorporates the pigments during the thread manufacture. This technique reduces the environmental impact compared to standard dyeing which takes place once the thread forms a fabric. This requires more water consumption and pollution. Our black MH100 fleece models use this dyeing process and we are in the process of duplicating it for the other colours. 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.
