Great for pajama shirts
Size: Large, Color: White 4-pack
Shirts are true to size. The material is soft and not too thin. We used these as pajama shirts for my preteen and he got a lot of use out of them.
Pro - cheap and well made
Con - they did shrink slightly after a few washes so the shirt is shorter. Didn’t impact our use though

Pay attention to the size chart
Size: Large, Color: White 2-pack, Size: Large, Color: White 2-pack
Good price for 2 undershirts. Retail price on the item packaging says $16.95. The shirts are thin and semi see-through but these are meant to be layered under another top. Have not washed yet but there's a good chance they will shrink a bit.
Had to return the first time because of inaccurate/unhelpful size chart. For reference, see the actual size chart on the product packaging (I attached to this review). Originally purchased a Medium for a 10yo average build child, it was too short. Large is the correct size.

X-small comparable to 2T
Size: X-Small, Color: White 2-pack
Got these for my 1.5 year old who fits in 2T pretty well, x small is perfect! They are so soft, a little thin but very happy with the quality

Perfect undershirt for uniform
Size: Medium, Color: White 4-pack
Material thickness:
I love how soft and thick the shirt is. My kid is comfortable wearing it an undershirt for his uniform. It does not make him hot.
Fit:
Perfect fir for 5yo 60ish lbs
