The only Men's Big & Tall Bamboo Viscose Clothing Brand in the World.
Big & Tall 3XL (XXXL) Bamboo Shirts – Crew Neck, V-Neck & Pocket Crew
Soft, Breathable & Built for Bigger Bodies
Finding the perfect 3XL (XXXL) t-shirt can be tough - most options are either too boxy, too short, or uncomfortable. At Big Boy Bamboo, we solved this problem with bamboo viscose shirts built for Big & Tall men. Our 3XL shirts are cut oversized for comfort, naturally soft, moisture-wicking, and durable enough for everyday wear. Whether you’re looking for a casual Crew Neck, a sharp V-Neck, or a Pocket Crew Neck tee, you’ll find your new favorite shirt right here.
Why Our 3XL Shirts Are Different
Not all plus-size shirts are created equal. We carefully designed our 3XL collection to give you the perfect balance of style, comfort, and durability.
-
True Big & Tall sizing – Not a stretched “XL” but a real 3XL cut for broad shoulders and bigger frames.
-
Longer length - Sits right where it should, with no riding up.
-
Premium bamboo viscose blend - Naturally soft, breathable, and eco-friendly.
-
Strong & durable - Wash after wash, your shirt will keep its size and shape.
Why Bamboo Shirts?
Bamboo viscose is one of the most comfortable fabrics you’ll ever wear. Unlike standard cotton, bamboo:
-
Wicks away moisture to keep you cool and dry
-
Feels softer than the finest cotton
-
Naturally resists odors and irritation
-
Is eco-friendly and sustainable
Our bamboo blend (70% organic bamboo, 30% organic cotton) makes each shirt breathable, durable, and silky soft - perfect for daily wear.
Choosing the Right 3XL Size
Our 3XL shirts (XXXL) are designed to fit comfortably without feeling tight or oversized. If you usually wear a 3XL in other brands, you’ll love the fit of Big Boy Bamboo. Prefer extra room? Opt for tall sizes, which add approximately 4 inches in length.
Eco-Friendly Packaging
We believe big guys deserve clothes that make them look and feel good - and that the planet deserves care, too. That’s why every shirt ships in plastic-free packaging: recyclable glassine bags and Kraft paper mailers. No plastic. No waste. Just great shirts.
FAQs About Our 3XL Bamboo Shirts

The best way to care for bamboo fabric is to wash it in cold water with an eco-friendly detergent and then hang it to dry. If you follow these care instructions, our shirts will not shrink and will last for years.
