My 6 year son has worn his size 6x/7 long sleeve version of this shirt for 2-3 days of every week this winter. Not kidding. He loves this shirt. We bought the short sleeve in a size 8 and its no bigger, not even a little..no discernible difference. I suppose I could try the size 10-12 for my 6 year old but that seems a bit far fetched. Sorry LL Bean, you came up short, literally, on this one :-(
I am having trouble with LLBean's sizing for Little Boys. I recently bought LLBean graphic tees in size 6x/7 for my 6-year-old, and they were WAY too long. So I bought this shirt in a 5/6 and it is nearly too short already. I haven't washed it yet, and am afraid it will shrink up further. I don't want to pay half the shirt's worth to return it, so I am stuck with it. Fortunately I have a 2-year-old who can wear it someday. I just wish the sizing here was more consistent.
I bought several of these for my picky boys, and am not disappointed! The shirts came out of the package with a soft, worn feel, yet have a crisp bright color. I washed them in warm water, and true to the name, they held their size and shape. My boys love them, and I expect them to last a long time.
The 3 tee shirts were purchased as a gift for a grandson, and although he liked the colors & feel of the fabric, the fit was a bit smaller (shorter) than other brands the same size.
