Product specs: 

The Mountain Equipment Mission Jacket is made from Exolite 250, a double-weave softshell fabric. The active cut, articulated sleeves and the stretchiness of the Exolite means the jacket moves with you without feeling restrictive. As it’s made out of a softshell fabric, it’s super breathable, making it an ideal jacket for active winter sports such as ski-touring and mountaineering; although it would look pretty good in the pub beer garden too. On top of its incredible stretch, it’s also wind-resistant, water-resistant (not waterproof!) and durable enough for even the most abusive climber.
