Mammut Mittellegi Pro HS Pant - Women's

Put your big kid pants on.

Whether you're walking in the footsteps of the infamous female mountaineer, Lucy Walker, or chasing your little mountain goats up the local sledding hill, Mammut's Mittellegi Pro HS Pant for Women offer nothing short of an amply-reinforced experience. Named after the Mittellegi Ridge of the Eiger, these pants were inspired by 80 years worth of mountaineering experiences on this peak. Built for the steepest of climbs, unruliest of storms, and loudest of laughter, these pants tells stories of FA's, exhausted limbs, and summit smiles as wide as the Eiger itself.

If you find yourself in waist deep in a snowy blanche, worry not—the Gore-Tex Pro fabric utilizes three layers to keep sweat, snow, and other weathery junk off of your skin for long term comfort, so you stay dry whatever the weather. In addition to being weather-resistant, the Pro 3L material is abrasion resistant, which will certainly come in handy when your snowy treks suddenly transform into rocky scrambles. The hem reinforcements and extra-high crampon protection serve as personal bodyguard for your ankles while the integrated ankle gaiters (with an adjustable hook-and-loop) prevent any sneaky snow from weaseling its way up into your baselayers. The full-length side zips permit impromptu bathroom breaks and necessary body heat dumps when your insides start to feel a reminiscent of a cast-iron pan.

Equipped with detachable suspenders, these pants have a girthy, raised waistband, perfect for keeping your internal goodies happy and far from topsy turvy. The Coolmax lining keeps your engine from overheating while the waistband can be adjusted from the outside to let out some steam. The leg pocket easily fits a trail map or a mini teleportation device, just in case the situation gets hairy.

Size up

  • Familiarity: I returned this product before using it
  • Fit: Runs small
  • Size Bought: 10

While I didn't end up keeping these, they are extremely well made! The two reasons I sent them back are that they don't have a thigh pocket and the ventilation/drop seat zips only go to mid-thigh instead of full-length, as advertised. My concern was that they don't have great heat-dumping capabilities for the skin track. I am 5'5" and 130lb, athletic and typically a six 6, but got these in 10. The fit was great... they have a very high waist which will protect your mid-section from cold. They are a highly technical pant that will give great performance and protection, no matter how extreme the elements.

Great, thorough review, thanks Bethany!!

Unanswered Question

The description sites a full-length zipper, but I only see what is clearly a bathroom zipper in the pictures. Am I missing something?

Great pant but very small

    I got a size USA 10 which is labelled as UK14 / EU40 and I am 5'5 and 132lbs. I would normally be a size 6-8 so I was thinking i was sizing up but they only just fit. I do tend to carry weight around my hips and thighs and that's where these were too small. They fit over one thin base layer but I would need to go up a size to get anything else underneath. Pity because apart from the the sizing they look awesome. I would need a 12 to fit anything underneath.

    Are these pants insulated? I'm looking for a gortex shell. Thanks!

      Love these, but they do run small

      • Familiarity: I've used it once or twice and have initial impressions
      • Fit: Runs small
      • Size Bought: 10

      I purchased last season's version but wanted to post the review to help others with fit.
      I'm 5'4", 150 (athletic with hips) and got the 10. They fit, but it was close. They are tight at the bend of my hips but fit like a glove everywhere else and are a good length for me. The waist wasn't too tight and the adjusting straps are great for a custom waist fit. The 10 was the last one available and I took a chance. Definitely got lucky in getting the right size, I would have normally ordered an 8. There is no give in the fabric. Construction feels great, all the material and seams are high quality. Very happy after having no luck with fit for the longest time - I just wore the $30 bib from my local sports store. North Face also runs very small on me given my hips and thighs, so even though I sized up the fit is much better with these.

      Wanted these to fit better

      The material is great, the attention to detail and how the pants are designed seems superb, unfortunately the butt just ballooned where the zipper is. If you're looking for technical pants, certainly a fantastic option as far a functionality, quality and durability. They pants themselves look great - just not on my body.

      Note: Euro sizing. I usually wear a small in other brands and I ended up having to order a size 8 in these. Check out the fit guide - it will help you out.
