My review is on fit, construction, and color.

XXL fit is roomy on 6'2', 235 lb. frame. I estimate that it should comfortably fit a 50" chest and 38" sleeve.

It's still brand new but it seems to be well made of comfortable cotton.  As others have stated, the cuffs are not elasticized but are a loose, open fit.  This could make a difference if your aim is to lock in body heat but, it also helps to allow you to push up the sleeve without fear for overstretching the opening.

The crimson color is closer to a bright red than a darker red.  The color sample on the Amazon site is pretty accurate.

In general, it's a good purchase for me.
