The second skin is amazing - it is comfortable, thin, and it really does stay tucked in. -Dave D, Bloomfield Hills MI
I love my Tommy John undershirt and I am going to replace all of my cotton undershirts with them - Benjamin M, Visalia CA

Fabric: Second Skin

  • The softest fabric on the planet
  • Anti-Pilling Micro Modal fabric
  • 90% Non-Pilling Micro Modal, 10% Spandex

Micro Modal is resistant to shrinkage and fading. Because we add stretch to the fabric for shape retention, the final product is not considered a 100% natural product.

History: Micro Modal,the world’s softest fiber, it makes textiles naturally more beautiful. Micro Modal fabric is feather-light and feels like a second skin on your body. The fiber is made from beech wood, a natural raw material. The natural softener makes Modal fabrics pleasant to the touch, even after repeated washing.

Problem: If you have worn modal products before, you know the problem is that they “pill” very quickly and look older, faster.

What we did: We are proud to use a revolutionary, non-pilling micro modal fabric that ensures garments retain softness and smoothness with NO PILLING; wash after wash.

What this means to you: Tommy John micro modal underwear remains as softly smooth as the day you bought them. The non-pilling fabric finishing process cleans away the fuzzy surface fibers that eventually cause pilling.

Wash after wash, your garment stays looking good as new, allowing you to continue wearing it for a very long time. No more pilling is pretty awesome.


If you're uncomfortable for any reason with your first pair of Tommy John, you can keep it and get a full refund. For full details, read more about our guarantee.

Awesome tee shirt

Been searching for many years for an undershirt that you wear and don't think about; coming untucked, too heavy, has seams that irritate your neck, etc etc etc! Found it. I was skeptical about the $40 buy in and I am 100% on board. Great product. Jp

Perfect undershirt

These undershirts fit snugly around the midsection, which takes a little getting used to if your old shirts were loose. However, this design makes it so that you look slimmer, the undershirts don't slip out of place as you move, and there's no unflattering bunching above the belt. Despite the cost, I have transitioned all of my undershirts to Tommy John ones, and I couldn't be happier. This is truly a perfect undershirt.
