In reply to LastBoyScout:
I spent ages looking for unpadded shorts which weren't flashy, long and not too baggy.
Ended up with Swrve Cotton Cigarette Shorts. Very pleased with them. Accurate size. The other Swrve shorts seem a bit baggier, although that depends whether your thighs are not skinny like mine.
I'm 5'10" and they are about 1-2" above my knee.
Smart without being too formal and I'd be happy to use them as shorts off the bike.
They've got a reinforced backside but I wear them over padded bib shorts.
Well recommended.
(If I wanted a pair of lighter material shorts, I'd also consider the Decathlon Forclaz 900 Hiking Shorts)
