Snow-blasted summits offer no mercy to fingers and the climbers attached to them; cover those digits with the Mountain Hardwear Nilas Down Mitten and gain a strategic advantage over the punishing environment. This tough mitt's high quality 800-fill down and an OutDry membrane provide protection from the coldest, wettest conditions, because the weather changes much faster than you can downclimb.

  • Waterproof, breathable, and windproof OutDry membrane blocks melting ice and snow; since the membrane is bonded directly to the outer layer it doesn't trap water and reduce breathability
  • Lightweight, but effective layer of 800-fill holds in the heat during the most extreme winter conditions
  • Textured palm grips ice tools and axes while you traverse windy snowfields
  • Polyester taffeta lining wicks clammy vapors before they collect
  • Long gauntlet fits over your bulky alpine jacket
  • One-handed SimpleCinch uses a Cyberian cordlock to keep out spindrift and dripping ice while securing your glove above an icy abyss
  • Very lightweight design packs down small inside pockets and packs

Great mittens

  • Familiarity:I've used it several times

I ordered XL so that I could wear a thin glove with them. Works better than expected. Since I purposely ordered larger than I would normally, can not say if they run true to size. I can say that the quality is amazing. The warmth is incredible and these are the best mittens I have ever had. So, so Happy with this purchase.

Seems ok but very large

  • Familiarity:I returned this product before using it
  • Fit:Runs large

I normally wear a large mitten but these are massive! I think I could put both hands into one mitten. I am returning for something else.

The rubber nubs on the palm seem well made and provided a good grip. I can't really judge the warmth since i returned them

warm, light-not as sweet as rabs mitts

  • Familiarity:I've used it several times

These are nice-super warm and light-but I prefer the rab endurance down mitts. The endurance down mitts are a bit loftier, a litle longer cut and have no elastic so they are a bit easier to put on when you are wearing a liner glove. I personally wouldnt wear anything thicker than a light windstopper glove in these-otherwise you would have to upsize 2 sizes which would make them near unwearable when you arent wearing liners.

Ive used them thus far to about -10-will likely use them in the next couple of weeks in the chugach or denali and will update.

Lastly-these are not meant to belay in at all-you will destroy them nearly immediately.

worth the money

    these things are super warm and are meant to be layered with another glove (but can also be worn solo. Very warm by themselves and with another glove underneath (MH hydra) you are good to -40 maybe lower! I wish they had different colors and I wish they had a wrist adjustment for when you wear them by themselves. Size is perfect not over the top gigantic like the alti mitts or masherbrums but getting close super warm. 4.5 stars

    Solved my cold-hands issue

    • Familiarity:I've put it through the wringer

    I'm very pleased I spent the money to get these down mittens. I have perpetually cold hands and so all the liners and hand warmers in the world couldn't do the job of these down mittens. My main winter activities are hiking, skiing and snowshoeing, and the mitten design is not much of a hinderance when putting on boots, adjusting straps, etc. Sure, it's not as easy as using gloves, but the trade-off for warmth by keeping your fingers all together is worth it. Put a pair of wool liners on under these and you are not going to get cold hands. I've had them out in -40 wind chills and my hands have been nice and toasty.

    Hello, do they have a liner inside? If I would wear it as the second glove on my windstoppers? Does S size not too big for my 7,5 size hand with the windstopper on it? Thanks.

    Best Answer

    Hey Maria,

    These have a polyester taffeta lining, but no removable liner inside. If your hand measures 7.5 inches in circumference with the windstopper gloves on, then I would suggest the size S. The best way to find your size is to measure with that windstopper glove on.
