What are the Gamma MX Pants?

The Gamma MX Pants are tough, wind resistant, water resistant and super warm trousers for use in cold conditions when you're not moving particularly quickly. They're ideal for expedition and alpine climbing, trekking and walking in winter conditions.

What are they made of?

The trousers are made from a thick, durable and highly abrasion resistant Fortius 2.0 softshell fabric. Fortius is made from a mix of polyester, nylon and elastane, meaning you have the comfort of polyester, durability of nylon and the stretch of elastane, providing the best of all three. A durable water repellent coating is applied to the outer of this fabric to repel moisture, however if the trousers do happen to get wet they'll dry nice and quickly. On the inside of the trouser is a brushed fleece lining which wicks away sweat, provides warmth and increases overall comfort.

What are the features?

Features of the trousers include a soft lined waist with an adjustable belt, two hand pockets, two thigh pockets (one with velcro, one with a zip) and a Keprotec instep patch to protect against crampons. 

How do they fit?

Arc'teryx give the Gamma MX's a 'regular' fit with a straight leg. The leg is neither narrow nor baggy and features enough room to move freely and to accomodate larger boots. A gusseted crotch combined with the stretchy fabric means you're never left feeling restricted.
