I live in Alaska and do quite a bit of hiking. I bought these boots in the summer of 2005 for my 6 week geology field course. I'll admit it took a long time to break them in, but once they were, well I wear them everywhere. I wear them in the winter when it's not too cold, the summer when it's not too hot, and all the time the rest of the year. It's now 2012 and I still wear these boots all the time. However, I noticed while hiking this past summer that there is near zero stiffness left in the ankle support; so I decided to finally buy a new pair. They were a winter holiday gift to myself so I could start the long break in period and be ready for summer!

I have to say, I almost love this thing. But I live on the Arctic tundra, and can't use it if it's colder than -20F or so. The tiny holes in the Windstopper fabric let in WAY too much cold air, and moisture builds up like crazy. I wore it at -30F and could feel ice forming on my lips. I imagine it's great when it's a little warmer; alas, that's not likely to happen here until the Sun comes back in late January. I'm debating between returning it or modifying it by sewing a layer of thin fleece over the breathing holes. It has good points, too. the thin fabric on the head is actually very warm, and with the hood of my parka keeps my head very warm even at -30F with wind. The piece that covers the top of the head also folds back very easily and comfortably, which is great for me as my head overheats frequently. If your plan is to use it somewhere frostbite in 10 minutes or less isn't a concern... I say go for it. If you plan to use it in an extremely cold environment, plan on modifications to avoid frostbite.

Love the way this jacket's made, seems to have good zippers and wrist cuffs, etc... but it's very light duty... by that I mean it's not warm. It does keep the wind out, but if the air is cold with out the wind, you will be too.

I ordered a size L because I have a tNF fleece that size that fits comfortably with some extra room. This parka was WAY too small! I sold it to my roommate and ordered a Marmot (XL was out of stock). He loves the thing, wears it every day.
