The Calanques durable trousers perfectly fit our Jasper jacket. They provide the same level 1 ARC protection, have matching designs and are also made of our durable Sio-SafeTM Essential Eco fabric. These sustainable trousers are very soft and comfortable. Their durable features can be attributed to using Eco-friendly TencelTM Lyocell and Repreve© recycled polyester instead of the regular cotton and polyester. In addition, they are designed for disassembly.
