My husband works in construction and is required to wear a high visibility shirt or vest.  He complained of the vest being too hot so we started a quest for affordable high visibility t-shirts.  These are perfect.  They are light weight and wear well.  Sizing was right on.  I have washed in warm water as they get quite dirty and they have not shrunk at all.  I would definately order from this seller again.  The product was exactly as described with very fast shipping.
