These are well made in terms of size and fit.  They might actually be the best made Fruit of the Loom clothes that I can remember buying.

So with that being said, why only 3 stars?  It's because these shirts are pretty thick.  If you are buying them to keep warm, then these are a 5 star choice for you.  If you are buying them to absorb sweat, they will be heavy and damp all day long (and making you warmer)
