the pants are probably new. just keep wearing them...the button holes will loosen up over time.
you can stick a pen through the hole when you aren't wearing them to spread it out some...but it's really not necessary.
does anyone know much about Chamula Knitwear? I just stumbled across them in the sale section on End. Looks really nice and beefy...similar to SNS. Curious how the sizing is and what other stores (preferably in the US) stock their stuff???
you might find the medium to be a little short at 6' tall. i'm 5'-8, 145 and i wear a medium in it....although the fit isn't super slim, the length is perfect.
last seasons henleys were much more slim cut than the current model offered on the website.
