Thierry, what were the problems with the G3 that you heard about?

This February I finally wore through my Simms Guide Waders. I sent them to Simms for evaluation and Simms offered to add about 15 or 20 spot patches to the ones I had made over the years, relace the right stocking foot (seams went), the left thigh and seat. I opted for a pair of G3s and am very pleased with them. What problems have you heard about?
