Care instructions

Fabric: Second Skin

  • Moisture-wicking, anti-odor performance fabric
  • 360 Degree Stretch Fabric

84% Polyester, 16% Spandex

Problem: Performance underwear rides up your legs when you move. This is due to the fact that they use 2 way and 4 way stretch. This type of fabric doesn’t stretch in all directions during movement, which is why it causes your underwear to rideup your legs.

What we did: Instead of endorsing a celebrity or an paying for an expensive billboard in Times Square, we actually invested time and money in searching the globe for a 360 Degree Polyester Stretch (performance) fabric that prevents this problem from happening.

The 360 fabric we use is designed to move with you, while staying in place. It is also moisture wicking with anti-odor properties.

What this means to you: Tommy John’s performance underwear doesn’t ride up your leg. The unique 360 Degree Polyester Stretch (performance) fabric stretches. in all 360 degrees that your body moves during activity to solve another problem we feel existed in the underwear market.

  • Softest cotton fabric you will ever wear
  • Dries 4-5x faster than other brands

86% Pima Cotton, 14% Spandex

History: Cotton is the most prevalent fiber in the world and is renowned for its breathability, strength and versatility.

Most of the men’s undergarment market uses only 100% cotton material. This is a strategy we believe to be deeply flawed. We begin with cotton, but also add stretch to the fabric for shape retention.

Problem: Traditional cotton undergarments tend to shrink up to a size smaller than you are, stick to the skin, cause you to overheat and sag when wet due to the weight of the fabric. They also stretch out over time, which cause an "A-frame" or "tented" appearance. It’s just a matter of time before these type of undergarments become rags for washing your car.

What we did: We found a super lightweight and smart fabric technology that uses a special cooling process to increase the absorption capacity of the fabric. Moisture is then transferred to the surface of the fabric where it easily and rapidly evaporates.

The non-pilling feature ensures garments retain softness and smoothness with NO PILLING; wash after wash.

What this means to you: Our Cool Cotton underwear remains as silky smooth as the day you bought them and keeps you cooler and drier than your traditional undergarments.

Wash after wash, your garment stays looking good as new, allowing you to continue wearing it for a very long time. Yes, this cooling technology is pretty awesome stuff!

  • 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 microfiber is too warm. The sizing on the website is different than the sizing on the box, According to the site I should order the large, Reality, I should have ordered an X-Large. The legs ride up, They require more adjusting than my $6 hanes Boxer briefs

Was really looking forward to this with all the hype but did not live up to hype and can't return them. Basically material is spandex. Very uncomfortable. Fly is nic but that's it. The underwear does ride up the leg

mostly good

first the good part. Tommy John is the only maker of premium underwear that makes one to fit us big guys. nothing in their description is wrong. the feeling of the material is great. BUT
The legs creep up into your crotch. The location of the fly is so high that when you are standing at a urinal it looks like you are playing with yourself, because you have to dig so deep. From the pictures of the briefs, their fly is about in the right place. Also, other makers of premium skivvies have a pouch that separates your package your from the rest of your body, and accentuates it, (That can boost your ego if you look in the mirror.)

Too Good

I have a least one pair of all three different styles(Second Skin-Cool Cotton-360 Sport) and this Second Skin is the best. All were great but Second Skin is like wearing nothing at all while keeping everything in place. What an elegant solution.
