How's the zipper quality? I've read several postings from people who have had trouble with their zippers soon after purchase.
I've read those reviews too... that didn't stop me from making my purchase though. They are YKK zippers and seem to be pretty sturdy. If they do mess up, there is a Lifetime Warranty and I'll just take it back.
For the price ($270 out the door), it really is a great deal. Comfort wise, I have no issues. Again, this is in the Texas heat. The quality of the leather feels pretty good as well. It might not be the same as the more popular brands, but you can definitely feel that it's going to offer better-than-skin protection. It has CE rated armor, which I have read is probably the lower end of the CE rated armor there is, but you can swap it out if you choose to do so.
There were posts that said it's just rebranded Frank Thomas. In all reality, for me... is whether or not it feels comfortable and safe. Am I able to afford the other brands (A*, Dainese, RS-Taichi)?... Absolutely. The majority of my riding is my daily commute, which takes me about 30miles total each day. I am actually considering picking up the matching pants as well.
On another note (in terms of CG brand quality)... In October of 2011, I had a mishap with another vehicle in an intersection @ about 25-30mph. I flew off my bike and hit the ground with one fo my Bilt textile jackets. I was not injured and if I wasn't wearing my jacket, I would have been messed up pretty good. The only damage on my jacket was a scuff on the shoulder where I landed, none of the seams were busted.
