I wanna to buy one WWII specification A2 jacket. I'm interested in the two brands cockpit usa and us authentic. They are not so expensive and I think both of them are good brand. In us authentic, I can choose nametag, patches and some other attachments. And they can sew it on the jacket for me. But there is no this service at cockpit usa. I like the patches on the jacket so much. I think cockpit usa is a famous brand in usa. And their jackets are nice. I lkie the "band of brothers" A2 jacket for this brand because of the patch on this jacket. But they have no nametag. I'm considering the quality of the two brands. I worry about the quality for us authentic becuase I found someone said the zipper was not so good and will be out of work in a short time. Is that true? So could you please advise which one I should buy. Thank you very much.
