The double-layer design gives it that grungy vibe without needing to actually layer two pieces, which is perfect for diaper changes. The heather grey goes with everything, and it's held up great through multiple washes already.

Bought this for my nephew and the double-layered look is exactly what I was hoping for—gives off that cool vintage vibe without being overdone. The heather grey color is nice and neutral, plus it’s super soft. He’s already worn it three times in the first week.

The ribbed double-layer look is cute in person, though the fabric feels a bit thinner than I expected for the price. It fits true to size for my 6-month-old, so that's a plus.
