Based on previous reviews I ordered a large (my head size is exactly in the med-lg crossover). It did fit fine, but it came with most of the pads no longer glued in place. Total Hockey accepted the return with no questions/concerns. Unfortunately, they had no more large in any color. I opted for a medium because the price on these couldn't be beat. At the largest setting it fit very snug the first time out, but that one game was all it took for the padding to form to my head shape. Now it is perfect, nice and light, and breathes great.
I wouldn't agree with previous reviews that complain of it running small. The size ranges might be a little lower than other brands and even some other Easton models, but if you know your head size, this helmet will fit you just right.
The dual nitrile padding is great. Much better than my Mission Intake this replaced or similar Bauers I wore previously.
