The concept is great. The fabric feels substantial but once you start moving it feels like you're not wearing a jacket. Zippers and buttons are high quality. I have a Rainier TPG jacket in XL for my cold weather riding and it is fantastic. I got a Large Tall in this jacket.
I'm 6'2", 190 pounds athletic build. According to Firstgear's sizing chart they don't make anything to fit me - a large is 42-44 chest with a 36-38 waist, a medium is 38-40 chest with 32-34 waist. I have a 44 inch chest and a 32 inch waist. That isn't the problem with this jacket. The sleeves, my god the sleeves! I'm not Ahnold sized, but I certainly have arms. There is no adjustment for fit on the elbows or forearm and there is enough material in that area that I can almost put a leg in there. The elbow armor becomes essentially useless since it just hangs off of you. It's like the designer only had Popeye to get his measurements from. It was a great deal from New Enough for only $59 (curiously enough, if you look now they cost $116), but it is going back. Competition Accessories has the old Mesh Tex 3.0 in a large, so I ordered one of them. They have sleeve adjustments around the elbow armor.
I'll update this review when I get the new jacket.
