I like Dickies products in general because they are thick and warm and durable. I have only had this product a short while, but so far I really like it. I don't like coats, so when it gets cold, I just wear one of these if am just running around town doing errand or hanging out casually with friends (not exactly the most fashionable hoodie). I find that it keeps me warm even with just a tshirt underneath. Also, the hoodie is heavy duty and is nice when walking to your car. Actually the whole thing is heavy duty. However, I find that if you zip it up while out and zip it down a little while inside, you won't get too warm even if you wear it for an extended time indoors.
The only caveat, is that you should wash these by themselves, otherwise they will shed on to your other clothes like crazy. Also a good idea to wash them before wearing them the first time. I have washed mine 4 or 5 times, and I still find the inside sheds on my tshirts a little, nothing too bad, but it definitely needs to be washed before worn, and it will shrink after washing too.
