The silky-soft, non-pilling micro modal fabric (no lint balls or fuzz) enhances this undershirt from Tommy John while the lay-flat, stretch rib Memory Collar eliminates "bacon neck." It has 30% more stretch and recovery compared to their original undershirt so it never loses its shape. Plus, the patented design never comes untucked so you don't have EFG®-the longer, tapered design eliminates "excess fabric gut."
