+n+1 on Ex Officio briefs. Stephen and I used them on our recent cycle tour. Two pairs each, one wear, one wash. 16,661km of high cadence cycling revolutions through deserts, tropical and alpine areas, plus town use on days off, about 240days. I'm still using them, can't tell any wear whatsoever...thats incredible, especially as they usually went more than a week between washings! Stephen's jocks are in the same excellent condition. They are going to keep on lasting for ages. No way a pair of wool jocks would ever last that long (we used Icebreaker socks on this trip, we wore through heaps of them, never buying them again...though they were really really comfy).
Yeah, they funk, but then we were always filthy anyway. When my shirt and pants are covered in caked on dirt and salt-stains I don't really notice or care that my jocks are funky.
Maybe I'd wear more holes in them if they had more to support? Haha...
