Love this thing, I wear L shirts and M jackets and it the M fits great 5'10" 190lbs. I live in CO so it's hard to find balance between warmth in 0-20 degree mornings and breathability and this fits the bill. I ride a train to work and rarely even start sweating with this on and it can get pretty warm on the train. Other jackets I've had that are this heavy I have to take them off or start sweating.

I'm 5'8" 180lb. I here the Marmot ares down jacket runs small . Will a large fit just right ?

Great jacket for mid-Atlantic winters. Daytime temps in the winter here in central VA rarely dip below 20's and are often in the 30's. For that reason I was looking for a down jacket for those cool evenings at camp but I didn't need a heavy thick overly warm jacket. The 600 fill in this jacket is the perfect balance. It does fit somewhat small compared to some of the other jackets but I didn't want a baggy bulky jacket so That isn't a complaint. So far it has kept me very warm. Another great marmot product.

Thanks for the review Chad!

Really nice and comfortable. I have not had anything go wrong with it and have worn it every day since I purchased it.

Pretty good jacket

This jacket is very good looking and comfortable but seriously lacking insulation. The neck could be a little more substantial too. This jacket is a great mid layer that I have used between 38 and 50 degrees on windy days. This jacket would be better if the pillows had something in them and were not so flat. Like another reviewer said the crease from shipping does not come out, at least not yet.

When will these be available in large and extra large again. Or are they discontinued?

Looks like there is Large available in green. Otherwise, they will come back in September.

I ordered the Moss/Midnight Forrest jacket. I'm 5'8 & weigh 120, so, I got the small one. It fits very well.
Sadly, I was only able to wear it once after a winter storm in LA. YES, it can get cold in So. Cal. I got so many compliments on it. It's very comfortable and the colors are great.
Btw, the description on here doesn't say, but, IT DOES have a zippered interior pocket.
All in all, it's a superior jacket. I highly recomend it.

See it in action.

What is the center back length of a medium?

28 inches

Is the 28 inches from the top of the collar to the bottom or from the base of the collar to the bottom... So closer to waist length or hip length? Thanks!!

Are the hand pockets of this jacket fleece lined?

Yes, the hand pockets are fleece lined.

Ares Down Jacket Review

    I really like the looks/style of the jacket. I got a small and the body is quite slim and the arms are a bit puffy. The arms also seem to have a permanent crease from being folded during shipping. It's been a few months and hasn't smoothed out. I feel like the proportion are a little off but otherwise nice. Light weight and warm.
