As someone who prefers the lightweight maneuverability of shell style snow pants, a good long underwear baselayer is a must for me. A great option for this service is the Mammut Go Warm Pants 3/4. The Go Warm Pants are made with a nice blend of fabrics that offer breathability, anti-stink properties, and warmth. I have a very tight fit with my ski boots and I like to keep my baselayers out of them; I often cut my long underwear to calf length. With the 3/4 length option, Mammut created an option that is great for people like me. The Go Warm Pants are also available in a full length if that is your preference and this review will apply to either length.
Mammut Go Warm Pants 3/4 Fit
I found the fit of the Go Warm Pants to be a little uneven but overall very good. The area around the crotch and thighs is more form fitting and I appreciated this design because it kept the baselayer from bunching. Gusseting in this area keeps everything in the right place without any annoying areas. Further down the leg, the pants become a little looser and not as fitted as I’m used to with my long underwear. I have fairly large legs and I was surprised to not fill out the pant completely. That said, I didn’t find this to be any sort of real issue and I forgot about it when using the pants in testing. The length of the Mammut Go Warm Pants 3/4 Baselayer was close but not perfect for me. Again, I have longer legs (being 6’1″) and they would probably be just right for anyone slightly shorter, or average height. With a tall sock, there was just enough overlap to keep my legs covered without getting any excess fabric in the boot. When I wore a lower sock, there was a small gap of bare skin. Might be worth trying out the Mammut Go Warm Pants with your ski socks before committing to them in the 3/4 length.
Go Warm Pants 3/4 Performance
These pants were put to the test in a range of conditions and did great when it came to comfort and temperature regulation. I wore them under my shell pants with no other insulation on a below zero day of standing on a World Cup skiing race course photographing the event and I did not want for warmth in my legs. That said, I tend to run a little warm but the point is that the Go Warm Pants provide great insulation. Waffle backing in the fabric is used in areas that lose warmth fastest. I also wore the Mammut Go Warm Pants 3/4 Baselayer on a more typical early winter day (~30-40 degrees fahrenheit) and was just as comfortable while hiking around and skiing with a pack on. As far as temperature control goes, the Mammut Go Warm Pants 3/4 Baselayers are a very versatile baselayer. To keep the pants dry, Mammut employed a mix of fabrics that wick away sweat admirably. Merino wool blended with polyester micro fibers bring sweat away from the body and allows it to evaporate effectively. I never felt the Mammut Go Warm Pants 3/4 Baselayer getting sweaty or damp.
Mammut Go Warm Pants 3/4 Baselayer Summary
Like most Mammut products, the Go Warm Pants are well designed, high performance, and useful. They belong on your short list for long underwear baselayers and can be used for a wide range of activities. They keep you warm when needed and wick away sweat effectively when you heat up.
