The Thermajohn compression shirt is a great addition to any active man's wardrobe. As my tests showed, it provides excellent muscle support and a comfortable, snug fit. The shirt is made with high-quality materials THAT keep you cool and dry during intense workouts. The only downside is that it can be a bit tight around the waist, but overall it`s a great product .I highly recommend it for anyone looking for a high-quality compression shirt..
