I spend many many hours outside.  I work in the construction field and am required to wear high visabilty "ANSI" rated vests.  Wearing this jacket replaces the vest.  I used to wear a Carhart or North Face coat with a high vis vest over the top.  The vests become combersome and a pain to keep track of.
The coat itself is just as warm as my North Face with the zip in fleece liner, and I feel like more thought has actually gone into this coat.  There are more points of attachment on this coat (two on each sleeve and a couple on the collar) along with the zippers.  I bought a size up so I could fit more layers if needed because I wasn't too sure on how warm this coat would be at such a low price point.  I really don't need the bigger size as it is plenty warm and I'm pretty sure I wouldn't need any extra out of the ordinary layers.  Next time I would just go with my normal size of XL rather than XXL but at this price I may just buy another one in the correct size and be donw with it.
I went to work with the coat on and by the end of the day 6 guys ordered coats.  Two or three ordered them right then and there on the spot!  There are a lot of these sorts of jackets out there and some are double to triple the money.  Trust me when I say this coat will be plenty and is well worth the cost.  I can't see anybody being dissapointed in this jacket.
