What is the fabric and how does it feel?

It is 80% polyester and 20% spandex. That blend stretches well and springs back, but it feels smoother and less breathable than cotton.

How does it fit compared with a regular long-sleeve tee?

It is a slim, stretchy cut. The chest runs about 34 inches at size M up to about 40 inches at 3XL, and the top length runs about 25.6 to 28.7 inches.

Yes. Machine wash cold and tumble dry low. The spandex holds up better with low heat than high.

It is a light layer. The mock neck covers the base of the neck, but the thin stretch fabric suits mild weather or layering under a jacket.

Yes. The mock neck and basic solid style sit flat under a blazer or crewneck, and the stretch keeps it from bunching.
