This looks like a nice shirt ... good quality, etc. However, I think the sizing is off. It is way too small. The M(10-12) will NOT fit my slim 12 (almost 13) year old this year. We also bought the "Coleman Double Pocket Flannel Shirt - Long Shirt (For Big Boys) Item #464MH" and that one technically fits perfectly, although I like shirts a little larger so that they will last an extra year, especially at this price. I would have purchased a Large (14-16) in both shirts if I had known how big/small they are. The Coleman shirt is just a little bit longer and wider, but the extra inch or two in each direction makes the difference. Both of these shirts are 100% cotton so they are both susceptible to shrinking.

Measurements: The longest part in the back from the bottom of the collar to the hem is just barely 24". The bottom of the front collar down to the front hem along the buttons is 21". Sleeve length is 20". Width under the sleeves is 16" (so 32" around). It fits my 10 1/2 year old daughter, but just properly as a shirt and not over anything. By contrast, the Coleman Flannel Shirt for Big Boys, measures: Length down the back is 25" and length down the front is 22.5". Width under the sleeves is 17.5" (so 35" around).

This is a good looking shirt and appears to be decent quality, but it runs small. A size large is listed as a 14/16 but it fits like a 10/12. Not sure what my return options are, but I am guessing I'm stuck with it given the price of the item vs. return shipping.

Runs small. Returned by my grandson.
