I'm 6' and 170 lbs. (I wear a size 40R suit jacket). Looks like I'm right between a medium and large. What size do you recommend?

Best Answer

Depends on what you'll be using it for...if its just to throw over a t-shirt or light base layer(s) I'd go for the medium...but if you're going to use it as a belay parka over multiple layers and a shell...go for the large!

how does this compare to the North Face...

how does this compare to the North Face Nuptse or Mountain Hardwear Sub-Zero? Is it as warm? recommendations?


Light, Warm, and Windproof?!?!

    Great jacket! It is the lightest 800 fill down jacket I've found and is the only windproof one I was able to find. Be warned, though. Like the other reviews say, this jacket is HOT and shouldn't even be considered for hiking or anything else that is going to be creating excess heat in.

    Down is best for those times when you stop moving (ie belaying) or resting after a climb, or around camp. It can be used aerobically but best only in super cold environments.


    great jacket

      The jacket was a present for my husband who is very particular about what makes a great jacket for him. He is happy with the warmth. He's happy with the color the style and quality. It's true to size including the sleeve length. Also he likes that it is lightweight and packable. At last a xmas present that was much appreciated.

      Any tips for a waterproof shell to go with...

      Any tips for a waterproof shell to go with this jacket? This jacket as been amazingly windproof and water resistant, but I'm looking for something to put over it when it gets to be real snowy or freezing rain. Not sure what shells fit well with this jacket...

      Depends on how much you want to spend, but for an overall, any condition shell I would get something with gore-tex pro shell. I think a good jacket would be the mountain hardwear beryllium, its not cut too tight and would go well with this down.


      Overall Very Happy

        Great jacket. It's super warm. The only negative is that the fabric on the top of the collar rubs up against my chin.

        I have narrowed my search down to this,...

        I have narrowed my search down to this, the the Mountain Hardwear Phantom, and the Feathered Friends Helios Jacket. I am looking for a light packable but warm jacket for BC skiing, hut trips, and yes, cold days in town. Does anyone know the fill weight on the Permafrost and the Mountain Hardwear Phantom?


        Go Hardcore

          This jacket is tough and completely windproof. I live along the Front Range in Colorado and the winters here are super windy, avg. wind speed is 55mph. This jacket blocks the wind and keeps you super toasty warm on single digit days. I've belayed in this jacket with great aplomb, I never felt the 25 degree morning air.

          Also, it is super light, like alien light. I think MontBell has their flagship puffy with this jacket. The shell is super strong, light, and very weatherproof, almost like a softshell. The insulation is amazingly warm, even with a long sleeve capilene 1-2 on I could be stationary for a while before I felt the cold. Nice weatherproof zippers to keep out moisture.

          The fit is athletic, I feel like. I am 5'10", 195 and the Large is so friggin money on me. Enough room to fit on a medium baselayer, and if it's super cold, a midweight insulation layer like polartec power stretch.

          Do NOT try and hike in this thing. You'll over heat immediately and be miserable. This is a stationary jacket due to it's warmth. Use it wisely and take it with you everywhere. It stuffs down to the size of a 1L Nalgene bottle with further possible compression available. Be sure, says the tag, to deflate slowly, due to the welded baffles and WindStopper fabric air takes longer to compress outwards, go fast and you'll blow out a baffle. No bueno.

          I like this more than my old favorite MHW Sub Zero Down jacket. It's just as warm but weighs literally ounces and is far more packable. Plus the Brick Red is like a salsa color, super dope.

          Great puffy

            After having to return a bunch of jackets due to fitment issues, this one is just right. I'm 5'10" 160lbs, and the medium is perfect. It's big enough to wear over my shell for keeping warm while switching modes in the backcountry, and looks so good I can wear it around town. The included stuff sack is great, and the jacket doesn't get too wrinkled when packed down tight. This isn't a super warm jacket, but serves as a great layering option, and will keep you toasty as long as you're generating some heat like you should be in the bc. The cut is pretty high, so if you like coats to cover your butt, this isn't it.

            How does this compare to the Alpine Light...

            How does this compare to the Alpine Light Down Jacket? Is the permafrost designed for a cooler temperature range?

            Best Answer

            The Permafrost has Windstopper behind the face fabric, which makes it a better outer layer in bad weather. The Alpine Light's face fabric is ripstop nylon, making it lighter and more breathable for layering but not quite as wind-resistant when worn alone. Wind aside, the fill weight (4oz) and fill power are the same, so it's more a question of purpose. Hope that helps.

            whats the different with montbell permafrost light down jacket and the montbell light down jacket?

            Best Answer

            Assuming you mean the Alpine Light Down Jacket, the difference is Windstopper. The Permafrost series has it, the Alpine Light series does not.


            Almost perfect

              I've had this jacket about a month. Keeps me warm at 40 with a t shirt. The wind stopper is probably the key. Seems to be well made (china). Fits snug, yet allows for a 300 fleece under without feeling to stuffy. Plusses are the velcro cuffs, drawstring waist, zippered hand pockets (fleece on one side), soft collar, flat finish (gun), the wind-stopper, and the light weight and stuffability. The only thing i really miss is an inside zip pocket. I'm really glad I went the few extra dollars over comparable jackets. I bought a small that fits well at 5'9, 145 lbs, 30 waist.

              Does this have pockets?
