We have sizes that go up to 8XL and 8XLT, so everyone can find the right fit for their height and build.

To find the perfect fit, there are a few measurements you’ll want to take:

• Neck size: Measure around the base of the neck where your collar typically sits for your neck size. 

• Sleeve length: Measure from the center of the back of your neck to your wrist bone for your sleeve length. 

• Shirt length: Measure from the base of the back of your neck down to your desired shirt length.

For more detailed information, check out our sizing guide or use our chatbox to connect with a Fit Expert who can help you find your perfect T-shirt style. 

While undershirts are primarily designed for layering beneath clothing, some styles and materials may be suitable for wearing alone. When paired with the right pants or shorts and men’s accessories, you can create a complete, casual look. 

The key to successfully wearing an undershirt as a regular shirt is choosing the right style and material. For example, you may pair an undershirt with active pants for a sporty look. If you’re going for a casual look, undershirts made from high-quality fabrics like cotton or cotton and polyester stretch blends offer breathability and softness, making them suitable for standalone wear. You can also opt for modern cuts and designs, including fitted V-necks or big and tall sleeveless undershirts. 

If you're looking for a stylish way to express your unique personality and interests, we've got you covered with our large assortment of graphic tees, collegiate tees, team tees,  moisture-wicking tees and more. 

And if you need a comfortable and functional big and tall T-shirt for your active lifestyle, our selection of active tees is sure to meet your needs.

The best material for men’s tall undershirts depends on individual preferences and lifestyle. Like with men’s underwear and pajama pants, you want to prioritize a few key characteristics, including: 

• Breathability 

• Comfort

• Moisture-wicking capabilities

• Durability 

For everyday wear, cotton is a popular choice due to its softness and breathability. For an active lifestyle, fabrics like polyester and stretch blends offer superior moisture control.
