You'll see some new Guys tees from this week's launched listed as "Fine Jersey tee" . We are testing out a different type of shirt with lots of similarities to American Apparel. Fine Jersey is the same type of cotton used for American Apparel tees.
You can find more about the measurements on our size chart: www.threadless.com/sizechart . The measurements on this particular tee type are a bit smaller than the American Apparel tees, however this tee is preshrunk so you should expect little or no additional shrinkage. After a round in the wash, the sizing will be about the same as your AA tees.
We'd love to hear what you think of them!
