Extremities Technology Explained

A lone hiker in a dark beanie, gloves and backpack stands on a grassy ridge looking out over a mist-filled valley and rolling hills beneath a low grey sky.

Next-generation performance. Built from the fabric up.

Extremities has spent decades pushing the limits of glove, hat, and accessory technology. From eco-conscious materials to specialist membranes that keep you warm, dry, and visible — every fabric in our range has a purpose.

Here’s what each Extremities fabric tech means for real-world use:
