It's long sleeve stuff I have a problem with sizes. I'm only 5'10" and about 210lbs. XL is good for short sleeve shirts, L for a tight fit. Long sleeve, hoodies, and coats on an XL the sleeves end up a couple inches from my wrist and XXL the sleeves are good and its way too big at the bottom. Was buying a new coat last month and ended up trying on an XLT and it fits perfect. Sleeves long enough without being stupid huge around my waist. Had to pay $30 more for a big and tall size, but worth it for something that actually fits right. Never really thought to try XLT before not being anywhere near big or tall.
