800 Fill Down

Certified 800+ Fill Goose Down bags are constructed with the following features:
- Nautilus Hood: the same construction as our 8000m jacket hood, a 3D hood that
wraps around your head and reduces heat loss. - Hood Muff: creates a warm down gasket around your face, keeping the drawcord
away from the face. - Stretch Tricot Baffles: allow the bag to be stuffed and unstuffed without tearing the baffle material.
- Trapezoid Foot box: matches the shape of your feet, wider in the toe area and narrower in the heels.
- Down Fill Oversized Draft Tube: eliminates cold spots
- Zipper guard: keeps the draft tube fabric from getting caught in the zipper
- Ground Level Seams: top layer wraps fully around the body creating a warm layer of down.

It would be NICE if the jacket weights would be listed on all items. Anyone with half a brain knows you really need to know the weight of garments especially when it comes to "ultralight" items.

I just bought one and its about 600g +/- 20g
on 5/16/10.
After checking out several down jackets, I found a sale from HTO in Washington D.C. The jacket is light as a feather (well of course, it's down) long enough to keep the lower back & upper butt warm, and the hood is really handy in our cold Sun Valley winters. NOt a ski jacket due to lack of all those usual ski jacket pockets.....but it is not marketed as a ski jacket. If something happened to this one, I'd buy another.

besides not having the pockets, is it a jacket you could ski in in light conditions ?
on 12/14/10.
it has pockets you just have to zip it down

I've owned this jacket since December. The weight- or lack of - is awesome. It is one of the warmest jackets I've had. My complaint- the shell is not very durable. I had this under my ski jacket, fell, and the minitool that was in my outer jacket packet STILL ripped through the shell. It's definitely durable enough for the city and light hikes. Apparently low branches have caught and ripped this fabric before, so protect it with an outer layer.

What is the fill weight?
on 9/2/10.
The weight of the Ama Dablam Jacket is 1lb, 20oz / 510.3g
on 10/31/10.
There are several different specifications to be looked at when looking for a down coat. 2 of the main ones that are often confused are fill POWER and fill WEIGHT.
Fill power refers to the down's ability to loft after compressed or 'resist compression'. 800 fill down refers to a 30 g sample of down being able to occupy 800 cubic inches of space after being compressed under a standardized force and fully lofting up again. 800 fill is a very high quality fill.
Fill weight refers to the amount of down in a jacket. The fill weight for the Ama Dablam jacket is 125g. For comparison, the Patagonia Down Sweater has 85g and the Feathered Friends Helios Jacket has 226g.
There are several other factors that play a role when picking an insulated mid layer: Baffled vs. sown through (the Ama Dablam is sown through => reduces weight but increases cold spots), mix content (feather vs. stalk ratio, the Ama Dablam has about a 90% down ratio) and the type of down (Goose vs. Duck, goose down for the Ama Dablam).
There are other things to consider as well, not pertaining to the fill of the jacket. The lining, shell fabric and extra 'features' like stuffing into it's own pocket.

Will this fit under a Marmot Troll Wall Shell Jacket, or is it too long in length? If it is too long, which is the best down jacket to go for?

I just brought one for my boyfriend..its light as a feather
on 12/19/10.
I really want to buy this jacket but i am not sure is this jacket to much silky,because i don't like that! Can anyone tell me about that please! Thanks!
on 12/26/10.
yeah its pretty "silky". It feels like ur average ripstop nylon type material. similar to an average sleeping bag. But i must tell u it is probably the best jacket ive ever owned. unreal in all sorts of conditions. just use a real lightweight shell in real wet stuff. must have!!
on 12/26/10.
AWSOME JACKET! a must have in the lightweight arsenal. Unreal weight to warmth ratio. Very useful pocket stuff sack. Great adjustment points such as the hood and cuffs. i would recomend to anyone...and i do on a daily basis because i work at a sporting goods store with a lot of other brands and styles. Better than the rest thats for sure.

Is this jacket waterproof? Will it stay dry in the rain?
on 1/14/11.
Hi Tom. The Ama Dablam is not waterproof. It is water resistant and will stay dry for a short time in a heavy fog or light mist.
on 1/13/11.
This is my first Marmot purchase. I am IMPRESSED. Above and beyond Northface quality.
This jacket is GREAT! Super warm, soft and light. By itself its warm enough to for the 20s and maybe the 10s. For the really cold and windy days just put a shell over it and you're ready for the 1s.
Hood is a great feature, large, adjustable and warm.

very good jacket, but the rain water gets into the seams

The Ama Dablam Jacket is not waterproof.

This jacket is awesome! Definitely my favorite cold weather jacket purchase yet. It is extremely light weight and warm. I purchased the Ama Dablam and another down jacket of a different brand, and hands down this one ranks better in almost every category I was concerned with (fit, warmth, weight, style, hood).
I would definitely recommend this jacket!

I bought one of these about a week ago. I leave up in AK and it offers great warmth, lightweight, and good looks. Trouble is that it already has a tear in the back! The fabric is really, really fragile. Like paper-thin fragile. Unless you plan to always cover this jacket with another layer or are extremely careful, it is just not durable enough for regular use.

Adam, thank you for your comment. Please contact our warranty department to have you Ama Dablam Jacket evaluated. Thank you!

Thanks to Moloch for providing some much needed information regarding the construction of this jacket.
Marmot- it would definitely help to know if a down garment is sewn through or box baffle constructed, as this is a distinguishing characteristic that we use to discern if a jacket is "parka worthy" for certain expedition applications.
Fill weight would also help when comparing garments online.
Thanks for the great products over the years, but please provide a bit more salient information in the descriptions.
