Thermoball technology is a revolutionary style of synthetic insulation developed by The North Face to bridge the gap between synthetic and down. Unlike continuous-filament materials, Thermoball is comprised of clusters that mimic goose down to create the pockets where heat is trapped. The Women's Thermoball Full Zip Jacket utilizes this technology. It is very compressible and light, and offers reliable thermal insulation (equivalent to 600-fill down). Now that I've finished that science lecture, here's what you need to know: when you're out in the elements and the weather takes a turn, you'll be happy you have this puppy on you to keep you toasty warm and happy (that's what it all boils down to).

SPECIFICATIONS of The North Face Women's Thermoball Full Zip Jacket
"This is a great jacket if you want a warm jacket for fall or early winter"
I bought this jacket for my mom. She really liked this jacket, but she returned it because she thought it would be a warmer jacket. It's great for fall or early winter, but it will not be your go-to mid-winter jacket.
"Very warm, awesome fit, and great color"
I bought this jacket right before heading on a trip to camp up at 10500 feet this fall. It got down into the 20s at night, and I was so glad I had my Thermoball. I layered it up with a thin sweatshirt and stayed completely warm. I have yet to test how it performs when wet, but I expect great things. The fit is super; I ordered the small, and it is form fitting bit still loose enough that I can layer lots underneath without feeling too tight. It packs super small too so it doesn't take up much space. The color is pretty much spot on with the picture here, but even more awesome in person.
