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.

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

Soft, comfortable and great value
Special Size: Tank Top, Size: 2-3T, Color: Tank - Toddler - 10 Pack - White, Special Size: Tank Top, Size: 2-3T, Color: Tank - Toddler - 10 Pack - White
I’m very happy with these Fruit of the Loom boys’ tank undershirts. The fabric is soft, lightweight, and comfortable for everyday wear. They fit true to size and hold up well after multiple washes without shrinking too much or losing their shape.
The material is breathable, making them perfect for wearing under school uniforms, T-shirts, or on their own during warm weather. The pack includes several shirts, which makes it a great value for the price.
Overall, these undershirts are durable, comfortable, and affordable. I would definitely recommend them to parents looking for quality everyday basics for their kids.

10th order, they do shrink after washing
Special Size: T Shirt, Size: Small, Color: T Shirt - Boys - 10 Pack - White
I guess its time to write a review. I've been buying these for 6 years now for my 10 yr old grandson. I have gone through every kids size S-XL I can unequivocally say they are the best! My kiddo will not wear any other pj top to bed , PJ day at school he will wear something "special" a matching set, but to sleep ...nope! The 7 pack works out to approx $3.50 ea. Pure white, pure soft cotton, no tags. They get softer the more they get washed. A little bleach they stay white. If they get stained...who cares .. remember 3.50 , yep that bad boy can hit the trash guilt free. Every single one of these Tees he has literally grown out of , none got holes . They are the best , softest easiest pj top ever. No trying to match bottoms he wears gym shorts . They are a heck of a great deal! Buy some! Order regular size..they start out big then shrink with washing. 100% cotton you should expect that. Grandson is 10 yrs old, 4'6" tall , about 92 lb.s L fits great , size up if you arent sure.
