Engineered with our signature 18-hour jersey fabric, this next-level undershirt was inspired by our youth, professional wrestlers and cyclists. Say goodbye to "Muffin Top" with an undershirt that stays tucked - always.
The Twosie: Feel like a kid again.
"I bought one for my dad!"
"I always needed Spanx, but was too ashamed to purchase them before. Thank you Mack Weldon! What an alternative."
"I’ll never have to safety pin my undershirts to my boxers again. It won’t come untucked, it’s literally impossible to untuck it."
"The first thing I do every morning is put on my Twosie. I love it!"
