Why We Like The Courmayeur SO Pant

Technical hiking trails and mountaineering expeditions demand proper apparel for efficient mountain travel, which is why we choose the Couramayeur SO Pant for our high alpine pursuits. We count on the Schoeller softshell material for its wind and water-resistance, and also for its breathability. These performance pants are perfect for high-output activities and they balance weather protection with supreme breathability in a way that only softshell pants can do.

Comfortable, keeps me dry in light rain

Used in alpine environment for several climbs. A bit heavy relative to other brands with comparable products, but it works, holds up, is comfortable, and I'm dry when using it. Fit is a bit snug, consider going up a size.

Pockets are bad

I have old version of this pants and I love them. New model mammut was able to make front pockets unusable. I cant put anything to hand pockets as it too tight and too high, phone pocket is atop of my leg and remove flexibility upon climbing or hiking. Although fabric quality is good

Ideal Spring Mountaineering Pant

Familiarity:
I've used it several times
Size Bought:
30 Regular

Great mountaineering pant. Waist was very comfortable and provided easy adjustment along the way. Material is flexible and breathes well - ideal for spring objectives and can pair with a base layer for colder mornings. Fit is on the trim side.

Apparently can’t exchange or swap for a different size.

I really did not want the athletic fit. I wanted a regular expected regular fit. I would like to have to exchange them for an athletic shirt or another product that I have. Probably won’t order pants longer too expensive not to be able to exchange your size is wrong. I have enjoyed the products over the years.

I'm ordering a second pair of these! I've had the first pair for a couple of years now, and they are very durable and fit great (and still in great shape). I've used them for Class 3 - 14ers, hiking, snowshoeing and trekking in Italy and love them!

Great simple pants. Size up.

These get 100 days of use a year in various wilderness settings. Biking, XC Skiing, bushcraft, seem to hold up season after season. These aren't carhartts... Not the best around fire, holes will melt with sparks as with any thin synthetic. Cinchable hem at ankles allowed you to pull pants up to knees easily for extra breathability. I had a snap on one of the cinches break. Would be nice if Mammut included an extra snap so that you can repair with like hardware. Great stretch and mobility. For some reason when paired with Murino wool boxers smell crept up. Work fine with cotton. Keep pockets zipped can tear if left open often.

Well-fitted, comfortable, protective pants

Durable, comfortable, fitted pants. Light weight for how tough they are. So far used for hiking in Canadian Rockies where some leg contact with rock inevitable but pants stood up to the test and provided the needed protection. Pants are appropriate for many activities including hiking, scrambling, mountaineering, and rock climbing. Good protection from rock abrasion, wind, cold and some water proofness. Suitable for all levels of participant.

Decent Softshell Pants- May be better options

I put these pants to the test by wearing them for 6 days straight while on a glacier trip... These were relatively breathable pants, although a bit thick for summer glacier days. There were times where they'd be too hot and I wish they had side vents. I did puncture a few holes in the legs with my crampons, but wouldn't expect these semi-entry level pants to prevent that. I did notice that dirt got stuck to the pants easily, so was hard to keep them clean. All considered, they were great pants that I'll continue to use for similar alpine & mountaineering objectives. I wouldn't recommend them for touring unless it's a day where your internal temperature fluctuates too much
