First impressions - Patagonia Better Sweater Hoody - Women's

I haven't been able to put this jacket to any real test yet since I just got it yesterday, but my initial impression is positive. I'm 5'4", 135lbs, athletic build, and I ordered a Medium. When I put my arms down the sleeves come down to the knuckle on my thumbs. The bottom hem comes down almost to the bottom of my butt. The hood is roomy, but the shape makes it feel like it wouldn't blow back in a strong wind. The general shape of the jacket is tailored so you can tell I have a waist, but it is generally a loose fit. This is what I was going for when I ordered it since I got it for backpacking and I need to be able to layer up under it. I ordered black so there isn't much to say about the color. It's black. The fabric is soft and warm. Everything about it gives me the impression it is a quality product. However, the true test will be how it holds up on my 5 day backpacking adventure in Peru later this year and how warm it keeps me.
