I've only worn this jacket for one day, so I can't comment too much yet on it's warmth (though it was a brisk windy 20 degrees and seemed warm with just a thin shirt underneath). As for sizing: I'm 5'7, 110 lbs. with a very long torso for my height and bought the XS, as I typically do with Columbia clothing. I'll admit to being a small-boned skinny girl, and I was surprised the XS in this jacket is almost too tight. It's wearable and looks flattering (even my conservative dad said it didn't look too tight), but it fits me like a second skin and there's no way I can wear a fleece or thick sweater underneath because it fits so closely in the waist. Arm length and body length are great - it comes just to the bottom of my bum. The black has a nice matte finish. I'm not a big fan of the appearance of the silver Omni-Heat lining, but if it actually works as it's designed, then it's worth it.

I'd say if you are between sizes, size up for sure - this one runs tight in the waist, and since there is a cinch cord at the waist, the next size up should still be flattering.

Sizing hints: I'm 105lbs 5'7 a VERY long torso.... the xs fit me (though no room for anything but a light layer underneath) but was too short in body length and the arms were almost too short. The small was surprisingly longer (by a couple inches), and still fit without looking too sloppy (though a smidge large under the arms), with room for layering. So, if you're wavering between two sizes and want a fitted look, go with the smaller size, if you need to layer- size up.

This pad is great. It's so much nicer than my old Thermarest- no more pressure pains in the middle of the night! It's so plush and comfortable that it's responsible for convincing my non-camping mother to go camping.

The foot pump works well, although adds bulk in terms of packed size. I also, cannot for the life of me, fit this back into the sack it came in. I paid close attention when unrolling it, but just can't get it to fit. Kind of a bummer, but getting/making a stuff sack to accommodate it isn't too big of a deal.

4 stars because of the stuff sack issue and not having used it for long yet- I can't attest to durability just yet.

I bought this kit last year and have used it with my thermarest - I have to admit, I'm kind of disappointed. I still wake up in the middle of the night with pressure points and have yet to get a good night's sleep with it. It's also pretty bulky once you've inserted your pad into it...not ideal for backpacking; more the size you'd take car camping. It's softer than my thermarest or z-rest alone, so I am thinking about giving it a second chance, perhaps with a big agnes aircore mattress. We'll see... it's an awful lot of money to spend for what little it seems to do. Three stars for the idea, happy green color, and in the hopes that with a thicker air mattress it will be as comfortable as I dreamed it would!
