True about the zipper tabs. I broke one off my left sleeve after getting that arm stuck between someone's rear wheel and hugger at 30mph. Might've been that that's what caused the thing to break, so I'm not complaining (plus, without the tab there's less bulk under the cuffs of my gloves). However, the main zipper tab in the front broke off as well after about a year of daily use, I put a key ring through the zipper thing and that works much better - I can easily pull the zipper open and closed now, even with my racing gloves on.
And yet one more thing: the zipper that zips the jacket to the pants is completely useless. It's made of plastic and very thin and flimsy. Mine broke after maybe three days of use, due probably in part to my crashes. I had Z-Leathers put in a copper replacement, no problems since. You won't have that problem since you're looking for a 1-piece, of course.
Despite the problems I still think it's quality gear, especially considering the price.
