i just road/run tested these on Hampstead Heath for an hour. Was definitely sweaty when I finished. Not as convincing as Bikram, but for those of us who don’t want to sweat heavily in a tiny room with twenty others, but want to run and heat the parts that the run can’t and a diet won’t shift- these might be the answer….Zaggora. Lots of testimonials on the site, see for yourself.. Basically feels like running in a wetsuit. I’m going to test the shorts at my next Bikram session. Euw..
