Sizing. Needs to be in measurements so the label size can be ignored. I have 36 inch arms, 6 foot 2 inches tall, a 34 inch waist and weigh. 185 lbs Ordered 2XL for sleeve length. Big enough for two of me. Sleeves were good. Sent back, no problem. Ordered XL, better but not quite . Kept these and ordered LARGE. Received these and PERFECT! ! ACTUAL measurements should be included in description to avoid this.Love the shirts, lite, airy, looks good etc. The lower arms get sunburned easily and need to be protected, the long arms do this well.
