Perfect
I actually wear thin bamboo / cotton boxer briefs, underneath these to avoid washing the SYB's too often. Still feels like not wearing these extra boxers at all, except in extreme temperatures. The SYB's are very odour resistant / dampening.

Awesome roomy briefs
These are really comfortable and high quality, shame they are often out of stock now!

Radiation proof
I dont have fancy tool to measure it but I did some test with different smartphones wraped in the boxer and it was effective to block incoming calls. Bravo!
