Columbia Tectonite Jacket Youth L 10/12 Yellow & Black, Insulated, Hooded, this is a great jacket with lots of pockets.  Used but in good shape, there was a tear in the outer shell of the right arm, I mended it and put a black patch over it.  Pit to pit is 20 inches, shoulder seam to bottom is 23 inches.

If you have questions or would like more pictures, let me know.  Thanks!
