just got these

just got these as I wanted something slimmer below the knee for ice climbing. lots of great design features, gator clip that tucks away when not being used at top of the list. definitely a trim fit, especially if you didn't skip leg day. tried them on with my normal base layer. my ass looks great...lol I'm 5'8" 170lbs and ordered a 32

Amazing pants

One of the best alpine/ice climbing pants I've ever tried so far. Fit is perfect. I am 5'6 and weight 165lbs and got a size 32 regular.

Extremely warm yet feel like normal pants!

These are an absolute must for extremely cold and demanding adventures! They are thin enough to be able to complete the most technical of approaches, yet warm enough for sub-zero tempos with a windchill of 30 below. Just a base layer under is all I needed while up the Rocky mountains.

Versatile

I've used it several times

Used for ice skating &cross country skiing in Alaska. Form-fitting but comfortable. Pares well with thin base-layer.

Top choice for heavy-weight softshell

I've had these pants for quite a while now and they've been my go-to for winter activities that don't warrant a hardshell. I've been ice climbing, ski touring, and mountaineering in them primarily in Colorado and Alaska. The features on them are great - they really stay out of the way. My only complaint/caution would be for athletes with thick legs - size up. The waist adjust is super flexible, so you'll be able to take it back out of the waist. I normally wear a 30 and I ended up fitting best in a 34 with the waist adjust cranked all the way down (leaving room for base layers, etc).

Incredible soft shells

For two weeks, I exclusively wore these pants in the Alaskan backcountry, skiing and climbing. I had an extra pair of softs that I never had to bust out. These were super comfortable, fit true to size even with a baselayer underneath, and we're incredibly quick moisture wicking. You can wallow in waist deep snow for hours and never feel an ounce of moisture. Wind protection was notable as well. The crampon pads in the back and the friction pads on the inside ankle were a nice addition. Helped to make sure my pants wouldn't ride up above my boot, or allow any snow in.

Quality at its best.

Purchased to wear alpine & ice climbing. The overall design and quality of the Mammut Eisfeld Advanced SO Pants is nothing short of top notch quality. I have a size 33 waist and ordered size 34 pants, they fit perfectly and the harness compatible waist band makes for a very comfortable fit when wearing a harness. Although it's a personal preference, I found the color Night nicer and not as dark as it appears online. Every feature is well thought out and executed.

Decent Softshell... Shells.

I would size 1-2 above your size to have enough room for layers. Decent design, stretchy. I'm not as flexible as these pants are. I like the crampon/ski edge protection on the inside ankle area.

Run small. Color is blue; not black.

Familiarity:
I returned this product before using it
Size Bought:
30
Weight:
170

I ordered size 30 since the sizing chart says 30.7" - 31.9" waist and I'm a 31" waist. These arrived and they are much too small even when wearing no base layer like I always would when wearing them and that was with the waist adjusted to the largest setting. Also, I'm slim and even this athletic fit was much too thin through the legs. Order at least one size up. A 32" might be right for me, but I won't be reordering due to the following color issue. These are offered in colors "Azurit" (a bright blue) and "Night" which appears to be black on the website. I ordered "Night" and they are a dark blue rather than black. I would not have ordered them if I'd known they were not black. Backcountry could help avoid returns if they stated a descriptive color to go along with the manufacturers color. In this case, something like: Night (dark blue). I'll be returning these, unfortunately. Even though I really love the stretch material and other features and one or two sizes up might fit right, they are not the color I want so I will be returning and not reordering.
