Arc'teryx Women's Atom Jacket

This jacket is so worth the $$! It is warm enough to wear in the 30s, yet you won't overheat in the 50s. There are three things that I must rave about this jacket:

1. The handwarmer pockets. Genius. The interior of the jacket is made of material that heats up when your body does, so your body heats up one side of the pocket and the other is fleece. Best handwarmer pockets I've encountered.
2. The breathable Polartec Powerstretch side panels. They are why this jacket is so versatile. While it really does heat up (esp under a shell), these help it breathe and regulate your temperature. Added bonus: they make you look thinner!
3. The fit. It is a tapered fit and is incredibly flattering. You can certainly fit layers underneath it, but it is snug.

Now for the other great features: beautiful color, awesome wrist gaiters, very light weight, and feels so comfortable.

As long as you use this jacket for what it is intended for, you should not be let down. Just remember it is a mid layer jacket, not a full on winter coat. It doesn't really block wind either.

I have had this jacket for 3 months- it is great!

It is warm AND breathable. For downhill skiing and sledding in -5 to -15C, I paired the jacket with a goretex shell, a fleece+thermal shirt underneath. Warm!

For cross country skiing in -10C weather (definitely a high-impact activity), I wore 2 synthetic layers underneath and was warm enough without getting overly sweaty and wet.

For going around town, I just wear as it is!

It fits well. Body fitting, such that you don't look like a marshmellow man, but still enough room underneath for a fleece or other thin layers. The cuffs are made of elasticized material that stops the sleeves from sliding down, even with raised arms. I also love the bright blue colour.

It is light! Like crazy light... How does something that is so small insulate so well? But it does! I like the feeling of not wearing a jacket while wearing a jacket.

My only two suggestions would be to 1. add a drawstring to the bottom hem and 2. raise the under chin cuff by 1 cm (when wearing alone, too much of my neck exposed).

I have the hoodless-version and it fits well under a shell.
