3 FIT Theory Fabric Swatches Photo
With Every New Fitting,
We include swatches of our fabrics
We want you to experience the fabrics first-hand
as you get to know your new favorite shirts.
3 Swatches Icon
Texture
See the texture in person. From solid to heather to slub, a swatch of each fabric is included.
Admittedly, it may be hard to get a true feel for the weight of a shirt from a small swatch, which is why fabric Weight is up next.
Fabric Weight Icon
Weight
The higher this number, the heavier the fabric will feel. Fabric is weighed in grams per square meter (gsm) or for us Americans in ounces per square yard (oz).
Fabric Singles Icon
Singles
“Singles” is the thickness, or diameter, of the thread. Specifically, it's the the number of times the yarn is twisted. Typically, the higher the number, the finer the thread and the softer it feels. More on that later #TheGladiator
Fabric Roll Icon
Fabric
Not all fabrics are created the same. Even with the same specs, other shirts will still feel differently, as not all fabrics, threads, and yarns are created equal. We only use the highest quality yarn. Better Ingredients. Better Pizza.

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.

About
“Slub” was originally a term used to denote an imperfection in the fabric, like a slight knot or lump in the yarn. But when controlled properly, it can give a unique, almost tonal, uneven surface to the fabric. This allows us to create a textured high/low patten that gives this 100% cotton fabric a very distinctive look.

100% Cotton Icon
100% Cotton
Unique Features
100% Cotton, but still has texture and a very distinct tonal look. Slightly heavier than the Shake & Bake, but it has a soft, almost “broken in” feel to it, like a well-worn perfectly broken in vintage t-shirt. It's brand new, but it might feel like it's been your favorite shirt for a decade or two.

About
Oh man is this an awesome fabric. Typically cotton at 18 singles is something called "open end" or "carded open end" cotton which is very rough to the touch. Not with us... not here. We've made an 18 singles 100% cotton, but with a high-end combed ringspun cotton. This way it gets that heavyweight feel and thickness, but still has a rugged softness about it.

100% Cotton
Unique Features
Thick and heavy, but still soft. It's over 50% thicker than the Shake & Bake fabric in your fitting. 100% Cotton, combed ringspun, and built to be worn.
This thing is a champion. It definitely ranks high on the “big-boned approved” scale, while still being appealing to most everyone with its soft touch and overall ruggedness. (We're just a “dependability” away from this turning into a pickup truck commercial.)
