I ordered this for my boyfriend for Christmas.  I had read the reviews before ordering and they were saying this ran big, so I ordered it in a 44short, but that didn't work out so well.  It was too short in the sleeves.  So I did the return through Amazon and sent it back.  To my surprise they had sent the new one back to me within days.  In less than a week from Christmas he had the new size that fit perfect!  Great return service from Amazon.
