It's been a long time since I teased our li'l buddy Guru, but he just typed he had the 185 in L and it "seems to run true to size"
Ok..now I've never met Guru, but from every account and pic on here, they all say he's a runt!
When the heck did a runt wear Large? I'm 6'2' @ 220# and I wear L under and XL outer for freedom of movement in hunting Gear...
Seriously, Guru, you wear L???
Now on a serious note, I invested years back in the Ulfrote Merrino wool... never quite bought into the "just hang outside and it won't smell" theme and my results have been unsatisfactory without washing between wearings as under-garments...especially tops, but sure gets softer w/ each washing and is nice and warm! The synthetic outer might be sweet, if it's QUIET.
I don't do anything that gives off the slightest 'rustle" warm or cold weather.
