thanks guys. i wore them around the house for a few hours and it has stretched a bit but i dont think its gonna get to a point where its comfortable for me. i made some measurements on my 634s using the iron heart measurement guide and the waist stretched out to a w36. so i think im going to exchange the 666od for a w36 tag size.
right now the measured waist size of my 666od is a 32 with a tag size of 34.
