Why We Like The Mammut Aenergy Air HS Pants

Pushing for the summit calls for pants that are protective from the elements but still allow our body to breathe and shed excess heat. The Mammut Aenergy Air HS Pants answer the call and feature a super breathable and waterproof Pertex Shield Air material for outstanding breathability and weather protection. Integrated gaiters help to keep the snow from getting into our boots, and the 3/4-length side zips allow us to dump excess heat when we get too hot. The waistband has external Velcro waist adjustment tabs, and leg width adjustments at the calf and ankle, allowing us to get the perfect fit around our legs.

Incredible wearable durability

Waterproof flexibility, I wear these women's ski pants everyday up on the mountain to work, love these!! The fit is amazing for us curvaceous women. Extremely durable and breathable. However not in below 0 extreme weather.

Great hard shell pants

Best hard shell pants I've ever used for ski touring. Fit is spot on and I love the full length zip. The material is light and not crinkly. As others recommend to size up I regret doing so as I max out the waist adjustment as small as possible and when I put my barryvox in it's dedicated pocket the pants still fall down a bit from the weight. They fit true to size.

Mammut Shell Pants

I ski in these pants at Mt Bachelor where I am a ski host. They stand up to all kinds of weather and fit well. They come in women's specific sizing which is great.

I have become Mammut obsessed as of recently, due to the high quality, durability, good colors, and affordability. I used to only wear Arcteryx or Outdoor Research, but Mammut has taken over, especially with Outdoor Research quality going downhill. After a recent Mt. Rainer attempt, I needed better Hardshells. After shopping around I decided Mammut was the way to go. I've got the Courmayeur Softshell Pant for ski touring/general outdoor activity, but wanted something more bomb proof and the Aenergy Air HS are it. I'm 6'0, 175 and typically wear a 32 waist paint. Considering Mammut is slimmer fit, and I'd likely be layering with the hardshell, I went with a 34 and do not regret it. With the adjustable waist I can wear these over the Softshell pant, with underlayers tucked in, and with the adjustable waist I can also cinch them down and wear them anytime. I've got an Outdoor Research hardshell bib I regret buying because these are so much more tough. Long zips on the leg allow ski boots/mountaineering boots through and easy taking on/off. Compared to materials, I feel like nothing could penetrate the Mammut material where the OR seems to lack. From Mammut I know have underlayers, fleece, hardshell jacket, softshell pants. My ski touring, mountaineering, and general hiking friends are jealous and just can't find anything this hard core with lightweight ability. Plus the colors just look great.

HS Dreams

These pants have been perfect for winter touring in the Tetons. I've always been a softshell kind of guy, but these make those cold windy days pleasant. I usually wear a 32 but went with the 34. I think it fits really well. They are slim fit with a velcro strap mid calf for cinching them down. They also zip from mid thigh down to your ankles for easy exits.
