Comments about Slovanian Wool Knickers:
First pair I bought at 32" waist, but (I'm about 31" in everything else) were too small. 2nd set at 34" waist seems a little small even yet, but I think they'll work fine.
I bought these for cool weather bicycling when it's too warm for my good wool pants and too chilly for shorts.
Very comfortable on the bike, but I've only worn them a few times so I can't comment yet on the durability.
