The only Men's Big & Tall Bamboo Viscose Clothing Brand in the World.
3XLT Shirts Built for Big & Tall Proportions
Ultra-soft bamboo shirts with the room, extra length and relaxed drape a true 3XLT body needs.
If You Wear 3XLT, You Know How Hard the Right Fit Can Be
-
The chest fits, but the shirt still pulls through the middle.
-
You finally get enough width, then realize the body still isn’t long enough.
-
Regular 3XL rides up the moment you sit, bend or reach.
-
Some Tall shirts add length but forget the rest of your proportions.
-
And plenty of brands stop their Tall line before they ever reach 3XLT.
Big & Tall shouldn’t mean choosing between big enough and long enough.
A Better 3XLT Starts With Designing for More Than Length
Adding a few inches to an ordinary 3XL doesn’t automatically create a good 3XLT.
A true Tall fit needs the right balance of:
👕 room through the shoulders and chest
👕 space through the midsection
👕 proper body length
👕 comfortable overall proportions
👕 the coverage bigger guys expect.
Big Boy Bamboo Tall shirts are designed with approximately 4 additional inches of body length compared with the corresponding Big size.
More Room. More Length. Better Proportions.
Tired of shirts that fall short—literally? Our 3XLT bamboo shirts are made for tall guys who want softness, breathability, and a little room to move. Longer hems, relaxed fits, and no plastic packaging. Style and comfort go hand in hand here.
Made from our signature 70% organic bamboo viscose and 30% organic cotton blend, these shirts keep you cool, dry, and confident—day or night. And with plastic-free shipping, you're making a better choice for the planet too.
