Jacket is extremely warm. I thought fit was ok. Takes a little adjusting to the "puffiness" of it. I feel like George C. in the Puffy Coat for all you Seinfeld fans. The down tends to leak out too which doesn't bother me, but my wife doesn't like all the white feathers on the seat in her cars' black interior.

I had a TKA 100 that I love that got melted from being too close to the exhaust on my leaf mulcher. This one is much different though. Fit is snug(unless I am gaining wt over the holidays? Bough a large and I am 5'10" ~190 lbs ) and the collar is cut in an odd fashion. I was going to return it, but the box and receipt got tossed.

I was looking for a backpack that I could carry-on to plane and use for a two-week trekking trip to Thailand. The air-flow back was very appealing because I sweat alot and Thailand is quite hot and humid. The problem was the arc in the frame was a concern though when cramming it into a overhead. The arc also made it more rigid so you couldn't stuff it as much. I really hated to, but I ended up returing it and wound getting a Osprey Kestrel 38 which looks like a better fit for my purpose and I got a few extra L's of space. My wife got a Osprey Talon 44 which is even better for carry-on travel. Very light and alot of room and still makes it in the carry-on restrictions. Osprey is a great pack and they are a great company. We called them and they were extremely helpful.

One other thing...they are supposed to be improving the Atmos next year so it should be even better.
