I'm 5'8 and the fit on the medium length wise is alright but ive got a big chest and shoulders which helps a lot in making sure tees aren't too long on me. If you're slim-ish and up to 5'11 then a medium would probably be cool. The large seems a lot bigger in both chest and length than the medium though so sizing up could be risky unless you do a lot of shrinking or like a pretty baggy fit.The classic/regular tees seem to run a tiny bit longer, from size medium and larges I own. TQL website says mediums are the same length in both classic and premium though, so it's probably the slightly larger chest on the classics allowing more 'hang' on the length.Thanks man. Is medium a good length overall or should I size up?
