Just received and "looking good"!
Just received the vest today, so this will a limited review. Thus only 4 stars for now.
My first impression was "The vest is very well made!". The material is very soft and the seams are constructed so the flat side is inward toward your body. A nice attention to detail. Zippers seem to be high quality and come with an extended grip tab which should come in handy if you're wearing gloves. There are two roomy hand warmer pockets (zippered) easily accessible, one each side. There is also an external pocket located top right, zippered as well. Size is fairly small, probably too small for most of the current smart phones, but large enough for ID, credit card, etc. Another zippered vest area pocket on the inside left. Again, fairly small, so probably not smart phone friendly. So, where does the battery go? Ah, Left side hand pocket actually has a small hidden (zippered) pocket where you will find the battery connector. Very nice touch. The collar needs a bit of explanation...simply put, I love it, but it may not be good for everyone. The collar is fairly tall and "fluffy", not meant to lay down. The zipper runs all the way to the top. It literally wraps you neck in warmth & softness. NICE!
Fit seems to run true. I'm 5'9" and weigh about 225 (yes, stocky) and the XL fits me perfectly.
All for now, will try to update after I test the heating/battery operation.
