The Mountain Hardwear Thermostatic Women's Jacket is Discontinued as of Fall 2017A technical jacket that has cozy features and an attractive cut and design, the Mountain Hardwear Thermostatic Jacket really impressed us. We thought this thin, lightweight jacket performed well during big adventures and still looked great; it's the lightest of the jackets we tested - packing down to the size of a one-liter water bottle. Throughout the testing process, we closely compared the technical attributes of the Thermostatic with the Patagonia Nano Puff Jacket - Women's, Outdoor Research Cathode Hooded Jacket - Women's, and The North Face ThermoBall Jacket - Women's. We approached these four jackets as a subcategory of the review since they were the lightest and most compressible and we wanted to see how they stood up against each other.
This jacket hasn't changed too much over the years, but this year they added a fancy new carabiner loop! Feel free to clip take this jacket onto a harness for any alpine adventure.
