Tommy John Men's Crew Neck Undershirt, Second Skin Fabric, Slim Fit T-Shirt with Stay Tuck Design, 3 Pack, Black-1 Pack, Medium

[ Most Comfortable Crew Neck on The Planet ] - We use only the finest, most luxurious stretch fabrics available and have changed the men's undershirt category with our patented Stay Tucked tapered design. This tee never loses its shape with 30% more stretch and recovery compared to our original undershirt. [ Patented Stay Tucked Design ] - This undershirt will never come untucked thanks to our patented long, tapered design. The length both keeps the shirt tucked and prevents EFG (excess fabric gut), keeping you looking your best. [ The Perfect Fit ] - Designed to fit your body and not a box, Tommy John's Second Skin tee hugs the body but is never restrictive. The micro-modal, spandex fabric blend moves with you instead of against you, providing an all-day comfortable fit. Wear unseen beneath a button up or dress clothes or as a stand-alone. [ Memory Collar Prevents Bacon Neck ] - Reengineered with our lay-flat, stretch rib collar, this tshirt will not stretch, giving you a "new tee" look for years to come. [ Sizing Made Easy ] - Our sizing is measured by chest size. Measure under the arms and across the fullest part of the chest apex including the lower portion of the shoulder blades. Small fits 34-37" chests, medium fits 38-41". large fits 42-44", XL fits 45-48", and XXL fits 49-52" chests.
