Shockingly great affordable basic T- Shirts
Fit Type: Regular Fit, Color: Black/Black, Size: 6X-Large Big Tall
I love these shirts! The fact they are big and tall is amazing. Better than Hanes, Fruit of the Loom, and Gildan. I am 6 foot 5 and heavier than I'd like to admit. I also have a wide chest 64 inches(Its hereditary). I need width and length! It is tough to find a shirt that is big and tall. Literally it's one or the other. Amazon of all places solved this. I did get two that weren't right they replaced them swiftly. Also for some strange reason white is a tad bit smaller in the same size. Usually it's the other way around with other manufacturers. I could not find black shirts that fit me comfortably for years! I was convinced it would be impossible to ever find any that would fit. This felt like a long shot and it paid off! Which is rare. I do not dry them in the dryer I know they will shrink(Probably wouldn't hurt to wash cold). If you want to dry them and you can I would go size up. Not too thin or too heavy wouldn't consider it an undershirt.

New default shirt
Fit Type: Regular Fit, Color: Navy/Navy, Size: Small
Amazon has again proved that it did good research about what makes a good basic garment. I've been wearing these for a few weeks now and honestly I forgot about them because they just fit and are not annoying and don't look bad. They are good. Also the cotton seems high quality and is soft. Also the small fit as expected.

Durable, Comfortable, and a Great Everyday Basic
Size: XX-Large, Color: Navy, Pocket Description: Plain Front
The Amazon Essentials Men’s Relaxed-Fit Heavyweight Cotton T-Shirt is exactly what a good basic tee should be—comfortable, well-made, and built to last. The heavyweight cotton feels substantial without being stiff, and it holds its shape nicely after multiple washes. The relaxed fit gives plenty of room for movement without looking sloppy, and the fabric has just the right amount of structure for a polished casual look. It works equally well for layering under flannels or wearing on its own. Pros: • Thick, high-quality cotton that feels durable • Relaxed fit for comfort and ease of movement • Retains shape and color after washing • Versatile for casual wear or layering Cons: • Slightly longer length may not suit shorter torsos • Limited stretch since it’s 100% cotton Bottom line: A sturdy, well-fitting T-shirt that’s perfect for everyday wear. Great quality for the price and likely to become a wardrobe staple.
