These Hanes T-shirts are a staple in my son’s wardrobe. The fabric is super soft and breathable, perfect for all-day wear. They hold up well in the wash—no shrinking, fading, or stretching after multiple washes. The fit is true to size, giving him enough room to move freely while staying comfortable. I also love the simple, classic design—it’s easy to pair with anything, from jeans to shorts. Great quality at a fantastic price. Definitely worth buying in bulk!

Runs small, great quality

Size: X-Small, Color: White 2-pack

Quality is great but the sizing isn’t what I though. My 3.5 year old (he’s typical size, skinny, not short but not the tallest kid) is in between a 3 and 4T. I bought the XXS and XS. Both were too small! The shirt also seemed like maybe a girls cut, the sleeves were short and it seemed to have a bit of a curve on the sides like some girls clothes do. I still gave 5 stars because they are really nice shirts for the money.

Value for money

Size: Medium, Color: White 2-pack

Good quality, material is thick and soft. Runs a bit small so I would rather size up next time.

Favorite White Tee

Size: Medium, Color: White 4-pack

Love these simple white tees. They don't shrink and are adequately sized. They wash well. My 6 year old loves them too. Light and comfortable. They can be dressed with jeans, shorts, work as an undershirt or pajama shirt. Favorite white tees for any outfit. Excellent priced. Great shirts overall.
