I have used the hanes classic tagless tees for years and have been relatively happy, but having lost some weight I wanted to find a better fitting undershirt. Wow. What a difference, both in quality of material and fit. A medium tee fits flawlessly on my 6'2" 160 lb. frame, and is sufficiently long to stay tucked in with dress shirts and polos. Whereas the hanes tees shrink in the wash, the polyester/cotton blend of these tees minimizes shrinking, keeping the fit consistent. The only minor issue I noticed initially was the seam at the shoulder which wasn't quite the smoothest, but they seemed to relax after a few washes. The best undershirt I've owned - period.
