This ended up being a great purchase, but finding any information about the jacket was frustrating and time-consuming. I hope my feedback will help others.
First for sizing: it appears to be true to size. My daughter is 5'2", 115 lb with a full chest. The size small fit her well and hit just at the top of her butt. It has enough space to layer underneath, but doesn't look oversized. She loves all the pockets that will hold a variety of items. The sleeves have velcro tabs so they don't hang over her hands...the sleeves don't seem overly long, but it's nice to have tat adjustment for more petite wearers. The teal green color is true to the picture.
The insulation is thin but quite heavy, so appears it will add quite a bit of warmth without bulk. The hood is adjustable both from the sides and back for a custom fit, and has a nice flap in front. The front zipper is YKK, so a top-of-the-line product and moves easily. The zipper is covered by a flap, so cold air will have a hard time penetrating. The pit zips are easy to use. She loves the silicone gaiter at the bottom to keep out snow/wind.
I was not familiar with this brand, so had to dig around the web for some info. Even the black crows website didn't list this jacket, so I had to go on other retailer sites to try and find info and reviews. It is still not clear to me whether this jacket is waterproof; it is not in the STP description and is not indicated on any of the tags attached to the jacket. I'll have to trust my research on other sites that it will repel water...this level of quality, as referenced by the base MSRP, should certainly be both waterproof and breathable.
While she hasn't used this jacket yet in the elements, it looks to be a high quality purchase. Please, fellow-STP shoppers, help out others by providing detailed reviews of your purchases. And to STP customer service, please resume your past practice of soliciting reviews from purchasers!

I'm 5'1". Opted for small. This pant was great quality. However, unless you are 5'9" or taller, this pant is not going to for! We thought it must be a men's pant the sizing seemed so wrong for a small. My 6' tall 170 lb husband out this pant on. Length was just right on him. A shame as otherwise, a very nice pant.

I've ordered these skis three times now and each time I get an email the following day saying they're unavailable. I'm not sure why they keep popping up on the website. As of right now, I still have a hold on the money I spent trying to get these for my wife.
