Mammut Base Jump Advanced SO Pants Review

Posted by Gear Pest Andy on

I've heard a lot of great things about Mammuts Base Jump Advanced SO Pants. My mate Rusty says his Base Jumps are his favourite ever kit purchase, so I was thrilled to get my hands on a pair in time for a 2 night trip to the Grey Corries, just east of Ben Nevis, for a bothy trip with friends in a right good cold snap in December 2017.

Leaving the car a Km or so south of the river Spean, our destination bothy, Lairig Leachach, was a further 7Km along the way to Corrour and Rannoch. We set off at sunset and with the freezing temperature set to fall further I had a pair of 3/4 length leggings on underneath the Base Jump Pants. Although perfectly warm, I could tell the stretchy schoeller fabric was breathable and made for a great fit. I like the draw string round the waist and found the pockets a decent size.

1 night and 2 drams too many later, and our group was to set off up the steep slopes of Stob Choire Claurigh. After some gentle exposure along the ridge to the summit, we descended further South and East before the sharp ascent up Stob Ban. From this peak we were to return to the bothy down its northeast flank for a second night playing cards by the fire.

With a more energetic day than the previous evenings stroll ahead, I had dispensed with my leggings. The temperature remained well below freezing for the entire day, yet even with an occasional fierce wind, of note on the exposed ridge and 2 target summits, my legs felt well protected from the elements. Again the schoeller fabric moved easily the odd occasion stretching for a foot placement was required. The 3 layer SOFtech fabric provides more substantial protection for your knees and bahooky (seat) and although crampons on this trip were not required, tough Cordura material on the lower leg gives edge protection from both spike, or ski edge.

I have found the Mammut Advanced Base Jump SO Pants a terrific purchase. Their moisture management was first class and they dry quickly. Without question they are now my go to winter pant for walking and climbing. I look forward to testing them spring ski touring also. I would be looking for something more substantial ski touring in January high in the alps, but the Base Jumps really are a great all-rounder.
