Durable trekking trousers with technical features, made from wind- and water-resistant G-1000. The model is based on our best-selling Vidda Pro but has improved ventilation options and a slimmer fit with stretch fabric in crotch so still has great freedom of movement . The buttoned strap adjustments at the leg endings can be removed and there are numerous practical pockets and details - such as a knife pocket on the right leg and a loop for an axe on the side of the waist. If you're already a fan of our trousers, then you can expect to go up a size in our Improved Fit if you wear an EU size 46-52 and keep the same size if you wear an EU size 52-56. Sizes 58 and above can go down a size, depending on fit preference. If this is your first pair of trousers, check our Size Guide to find your best fit.
