WARNING
Your Life is About to Change
Everyone
Feels Like
a Model
in Our Shirts.
[IMG: 3 FIT Theory - Everyone]
[IMG: Not Too Seriously]
We Don't
Take Ourselves
Too Seriously
Everyone does look cool walking away from an explosion though
But,
We Do Make
The World's
Best Shirts
Bold claims. We'll back it up. Don't worry.
[IMG: No 1 Fit For Every Body]
THE PROBLEM
Why do we accept the Bull S%^t?
[IMG: Why Accept BS?]
[H3]
This industry hates you.
Why do you have to worry about shrinkage? And inconsistencies in sizes, even in the same brand? Guessing between sizes and hoping it doesn't shrink.
What if it didn't have to be that way?
What if something came along and fixed it?
[IMG: Cut Plus Grade Equals Fit]
[H3]
Shirt sizes are dumb. “Fit” is all that matters.
A typical shirt “Size” is both a “Cut” and a “Grade” (ex: Small, Medium, etc). So a typical “Size” hides an implicit decision about the Cut of the garment. And, there's no 1 “Cut” that works for every body type.
[IMG: 3 FIT Theory - A Fit for Every Body, from muscular to big boneded]
[H3] A Fit For You, A Fit for Every “Body”
Muscular? Big Boneded?
There's no “1 Fit” that works for every “body” and everyone's preference. We send you 3 different fits in your “size.” From tall to small, from big to narrow, no matter your body type, we have a “Fit” for you.
[IMG: Shirts for Tall Guys]
[H3] Tall guys? Yeah, we got you covered.
Length without the width. There's a “fit” for you. Sit down with confidence that you won't be mooning the people behind you. Raise your arms without fear of midriffing everyone. Yeah, we got you covered.
[IMG: Muscle Fit Tees]
[H3] Work out a lot?
Broad shoulders, smaller waist? Yeah, we even have a fit for you. Room in the chest without being too baggy in the body. We got you.
What if,
You never have to shop or try on clothes again?
[IMG: 3 FIT Theory - Never Have to Shop for Shirts Again]
[IMG: Frustrated by Fit]
What if
Your favorite brand
actually cared
about you?
[IMG: 3 FIT Theory - Make It Simple]
And,
Empowered You.
Gave You Choices.
Made It Simple.

DURING YOUR FITTING
Focused. By design.
One fabric. Two colors. Two necks. Three different fits. We hold every variable constant except the one we're testing —
fit.
Shake & Bake fabric (our most versatile)
Black or White
Crew or V-Neck

Access Everything
Once you've found your fit, the full catalog opens — every style, every color, every fabric. Plus Preferred Pricing on every order.

Why so focused during the Fitting?
Because it's what matters most. Strip out the noise — color, fabric, neck — and the answer becomes obvious. That's the theory in 3 Fit Theory.
