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.

The best!

I haven't worn an undershirt that even comes close to Second Skin. It's a perfect product.

Neck opening stretches too much

While I love the fit of the shirts, I do not love how much the neck opening stretches out with repeated washings. It disappears underneath open collared shirts. My multipack shirts seem to maintain their neck shape better. The ribbing around the collar needs to be thicker and more robust to prevent this from occurring. If this was corrected, the shirt would be five stars.


Eliminates EFG™ (excess fabric gut)
