by fromMy son loved it It is not often that I get an unsolicited call from my son just to tell me that something I bought him was perfect. Well, my son did just that a week after I gave him this jacket. He said it is extremely comfortable and the perfect layer. He told me to get ome for myself. I think I will.

by fromInsulated jacket that attarcts the ladies. A very nice fit, I got compliments from women when I wear this jacket(unknown bonus). I only put this jacket to work on a 8 mile hike thru topanga canynon. I kept me warm from 1:00 am to 2:30 am. It actually kept me too warm... It does its job pretty well. I get cold easily, for me cold is 65 and under. Thats cold weather for us angelenos. The few times i have worn it in non hiking situations women tell me I look good in it. I plan on wearing this jacket every time i get.

by fromGood but not great. I ordered this jacket a few weeks ago and I've been mildly satisfied with it. It's much thinner and lighter than I thought it would be, but that's not necessarily a bad thing. I've been cycling in it in 25 degree weather and it's definitely not very warm. My 4 year old Marmot equivalent is much warmer. The material looks great, but it definitely won't last long in the woods with thorns and branches scraping against you. Also, the zippers feel cheap and don't function smoothly. Overall, this isn't a bad jacket. It just doesn't have the warmth and durability that I need. I'd use it as casual clothing in an urban environment, but never on the trail. My decision is to return the jacket next month because it doesn't fit my needs.

by fromSweet Jacket! I bought this for cold weather running, shoulder season climbing, and as a mid weight layer. I haven't used it for any of the above yet. I have been able to wear it around town and like the look, feel, and breathability. It is an athletic fit. I purchased a large, but would've gladly taken an xl if they had it. I am 5'9" and have an athletic build. I do have large chest (46), and back muscles, so it's a little snug in those areas, but otherwise it fits fine and climbing mobility is good. The hand pockets are not harness or pack friendly. It has a chest pocket and hole for ear buds. Not important to me as I don't listen to music when climbing or on the trail. The pertex is tough and water repellent. I like the breathable side panels and arms. This is my first garment with Polartec Alpha as most of my outdoor gear is either primaloft or 800 fill down. Today was about 45 degrees and I was wearing just a short sleeve shirt underneath. I felt comfortable, not too hot, not too cold. Just right. Curious to see how it will perform during aerobic activities.

by fromWorth every penny I wanted something light that could retain warmth in the coldest of conditions; this jacket is very light and has a slim fit but keeps you very warm. I wear this every day, it's great for driving as well because I can't drive in bulky jackets. I would recommend this to anyone who wants a thin, light but warm layer; when it's real cold I wear a hooded sweatshirt underneath it and it's incredibly warm because it retains heat.
