I’m new to beekeeping and so, have owned exactly one suit. And worn it exactly 3 times!
So far, I really do like it. The fit is perfect, the round veil doesn’t make me feel claustrophobic, and the ventilation is good (ask me again in summer!). Unfortunately, I can’t offer specifics as to country-of-origin or zipper materials, but the quality seems rugged to me so far.
I imagine that eventually I will get comfortable enough with working the hives that a jacket/veil or veil-only configuration will work just fine, but for now this suit gives me a lot of peace of mind.
