We engineer the fit of our products to help aid freedom of movement and enhance comfort during the intended activity.
Our products are defined in three fit categories, Active Mountain, Classic Mountain and Mountain Run. This is to help you choose the right clothing for the right activity and ensure the product fits as it was designed, for optimal performance.
All our fit categories take into consideration layering systems. For example, if you fit a size medium Active Mountain Fit baselayer, you will need a medium-sized Active Mountain Fit mid-layer and the same in a waterproof. Similarly, our Classic and Slim legwear take into consideration what you may wear over or underneath in various conditions, a winter weight trouser will have the space to wear Long Johns underneath (or Long Janes).
Please note all measurements are approximate. We reserve the right to amend specifications in the interests of improving our products.
