Far IR Clothes

Hey all,
To all who praise the positive effects of FIR heat on PE. I like the idea of using IR as a heating source given its ability to penetrate skin and get in there with the ligs. But I don’t have the luxury of using a bulb because I do discreet PE. So in searching around I found clothes made up of FIR fibers. They are supposed to be able to use the energy given off by the body and convert it into FIR heat. I’ve never used it but it sounds promising. They report increae oxygenation and overall blood flow. I went ahead and ordered the wristbands and think I’ll slide it on as I’m using my extender. I’m wondering if anyone has had any experience with this type of heating device. Any thoughts are appreciated as always. Heres a link to one website selling the stuff for reference.
