Lands' End Canvas - Page 206
Lands' End Canvas has been a little bit hit or miss for me, but the poplins have been pretty good (vs. the madras, which felt really cheap). For the record, I'm 6'3" with a 38" chest so I get mediums. Sleeve length (~34 in the M) and neck are always good, but sometimes the chest and body are on the loose side.
If the selvedge patterned poplin goes on sale again (Nearly everything LEC goes on sale eventually), go for it! A really nice shirt.
I agree with the fits, they are a bit of a hit and miss. I normally wear Medium in most brands and all my LEC shirts are small. Their mediums are always too big on me. Of the smalls, Some fit great on the body, one is a little loose, and one or two are a tad too tight. All of them are a tad too tight around the neck if you button them all the way up, but I wear them casually untucked and they are always the right cut/good length for that.
