Limited Release!
Black Crew Necks
Are available for the fitting.
Then, limited colors and styles are available, once you find your fit.
And, we're actively working on more colors, styles, and fabrics now.
We know a lot of brands never have "Real Men" or "Big Guy" sizes, so this is your chance to participate.
Our initial testing has been overwhelemingly positive... but we want more feedback. We want to hear from you!
3 FIT Theory - Check mark Icon
  • Nothing to join.
  • No yearly fees.
  • Not a subscription.
Here's how it'll work:
  • We send you 3 different fitting shirts, not just sizes.
  • Try them out! Wash 'em! Wear 'em!
  • Tell Us What You Think!
Then once we launch them in full, we'll let you know what changes we made.
And as a thank you, you'll receive discounted Preferred Pricing for life on all future orders of additional shirts. (More on that later, further down this page)

Your Fitting
What “Size” Do You Typically Wear?
We use this as the starting point to find your fit.
Note: Our Shirts Don't Shrink.
“Tall Size” Info ▸
Length?
Note: only “Standard” and “Tall” for now. Will eventually make “Less” versions, too.
Crew Necks
All 3 shirts will be different fits in the neck you choose.
Note: only Crew Necks are available now. We will eventually make all of our styles.
Only Black, For Now
We've only made these new test fits in Black Crew Necks at the moment. Eventually, once we finalize the fits, we'll expand them into all of our colors and styles and fabrics.
Fabric
We use our “Shake & Bake” Fabric for your fitting. All Fabrics are available to you after your fitting.
Shake & Bake
50/50 Cotton/Poly - 145gsm (4.3oz)
“Equal parts awesome & goes great with everything. A truly versatile fabric and great for all-day wear.”

About
This is the fabric we use for fittings. Why? It's universally loved and good for almost everything: gym shirt, undershirt, and everyday wear. It's an equal parts blend of 2 different fabrics and great for its versatility, quicker drying, and a bit of moisture-wicking built in. It's soft, yet durable, and great for all body types.
