Why Accept BS?

Why do we accept the Bull S%^t?

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?
Cut Plus Grade Equals Fit

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.
3 FIT Theory - A Fit for Every Body, from muscular to big boned

A Fit For You, A Fit for Every “Body”

Muscular? Big Boned? 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.
Shirts for Tall Guys

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.
Muscle Fit Tees

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?
