Marmot 8000M Down Pant - Men's - 2007 BCS

Marmot 8000M down pant is the best and most practical for extreme weather cold conditions. I specially like the elastic ankles, and simple design with no addtional fluffs.

It is considerably light for its warmth and fill weight, also heavy duty full side zipper works very well.

Velcro on the suspender should be little longer to accomondate short torso.

Overall, this is one of the very best insulating gear.

I find Marmot gears to be conservative in design but most practically in application.

I bought these pants for a recent recreational trip to Hoth.I'd heard that the temp there routinely dips down to around -700 degrees at night, and I wanted to make sure I wouldn't have to sleep in a Tauntaun.Needless to say, they were exceptional.Super warm, super comfy, and actually incredibly durable. Over the two weeks we spent there, I think I only took them off once. And that was to pee.So if you're considering getting these pants, I highly recommend them.Seriously.

These pants are so thick one can hardly move in them. And they need a waist adjustment possibility.

Otherwise, they are the warmest out there and the suspenders are really wide, well designed and comfortable.

Another inch in the inseam would be welcome. But for the absolute extremes of cold, these are it. And they even have a pocket. Just be careful trying to run in them. (-:

I tested these in my works walk in freezer where the temp is -4F and I was super hot even doing little or no work. They are so full of high quality down and are reinforced with thicker material around the knees and but. The overalls were a bit big so I had them altered with extra Velcro higher up so they fit on my waist better. I sized up to a large so they could easily be placed over my shells for Mountaineering. Can't wait to try these out in some serious cold weather. Not only did they come with a stuff sack but also a storage sack. Nice work Marmot! Perhaps on the 2010 model they will have more options to tighten the waist a little more to keep the warm air in.

A year later (3/29/2011) I called Marmot and asked for the down fill weight of their 8000M Collection, this is what I was told:

8000m Pant - 296grams / 10.44 oz
8000m Parka - 504grams / 17.77 oz
8000m Suit - 692grams / 24.4oz

Super puffy pants. Because they are so thick and puffy, it would be a good idea to order a size larger. I typically wear S but after reading a few reviews, I ordered M and it fits me just right. The leg inseam section is bit short. Another reason why it is a good idea to order a size up. I tested these pants when I was in Summit, Greenland. They were warmer than my -40F rated sleeping bag. I just slept in these pants! If you are wearing a thick sweater on top, then the suspender will not feel loose or too big (only the case if you ordered a size up).

These pants are just superb. Although I hav;nt tried them in higher altitudes, they kept me warm and nice in the cold of Finland for nearly a day without too much physical exercise. Easy to get on and off. I can;t wait to get the parka of the same brand.

I bought these for my son who is standing at the base camp of Aconcagua as I write this, so a performance review will follow. The sizing was a little off. Al is 6' 1/2" and 175. We ordered the large, as it fit his measurements. When he tried them on, they were really too short through the crotch. Had to make due because of timing, but XL would have been better.

Very warm, I suppose. But clunky.

A draw string waist would have made the difference, since there is only one other pants this warm: the Mt. Hardware Absolute Zero pants, also without a draw string, though the description says it has it. Both went back: Why have all that warmth, if the waist is loose and lets it out???

And the suspenders should be wider and padded, or something, to make them more comfortable. Though the insulation is lightweight down, there is so much of it that the pants weighed heavily on my rather thin shoulders, and annoyed me immensely. They are also stiff-feeling because they are so stuffed so full.

A redesign, making these pants more comfortable and with adjustable waist, would make it a winner......though I could do without the wild coloring.
