I've tried lots of sunglasses over the years, and most of them came from Hidalgo's. He has good products at a good price. For years I used glasses with the thinnest temples I could find so I could get a good seal with my headset, and the best I found were some I got from Hidalgo's, Carlo Bellini brand IIRC, and I don't think they're carried any longer. Now I'm using a set of Randolph Engineering glasses I got free from Professional Pilot mag for returning a survey. I've discovered lightweight in-the-ear headsets, which use foam earplugs, and I can use whatever glasses I like, because there is no heavy, hot dome over my ears. I get better noise reduction than what is advertised by ENC headsets, with Howard Leight Laser Light earplugs giving a NRR of 32. They're light, cool, and quiet, and I don't have to take the button off the top of my cap. There are at least 3 brands available, and Google should turn them up for you.
