We purchased this shirt for our summer at the beach.  My son is five, 49 inches, and 52 pounds and the size 8 just fits him - so the shirt is cut on the small side.  He usually wears a size six in clothes.  The shirt is light enough in color to not absorb the hot sun but dark enough to not show any discoloration from the salt water or pool water.  The shirt has a slight mock turtle collar, which allows for a bit of his neck to be covered.  He feels comfortable in the shirt and it dries quickly.  The only other issue besides it being on the small side is that the little picture on the front is half peeled off after less than a month of wear.  I would recommend this shirt for affordable sun coverage.
