Mammut’s extremely well-proven and popular Base Jump Pant now has the added bonus of being called Advanced, although its design remains the same as the classic version that I’ve personally been wearing for many years now. The trouser is made from just about the perfect weight of fabric, which means you can wear it all year round and not overheat or feel cold. In the height of summer shorts are the alternative to these for me. The fabric has just enough stretch to allow a comfortable, relaxed fit with reinforcement in the seat and knees. The waist is elasticated and has belt loops so you can ensure it fits well, and the knees are articulated for a better fit too. There is a leg gusset and Velcro adjustment to tweak the fit in this area to suit your boots or activity. Pocketing in the Mammut Base Jump Advanced Pant is pretty good with two hip and one thigh pocket, although I’d like the thigh pocket to be 2cm bigger so I could fit an OS map in it with slightly greater ease. There are loops to attach braces but these are not provided (they again would have been a nice addition).

The Mammut Base Jump Advanced Pant is a popular and classic trouser that most hillwalkers will find ideal; but there are some features, which you might like, that they are lacking.
