Purchased in 2024. These are 100% cotton overalls. They have shoulder straps (no adjustment function), so there's no worry of them slipping off. The chest area is a bit tight, but the gathers provide some stretch, so it wasn't too constricting. While they are not waterproof or stain-resistant, they were very useful for outdoor play because they kept the stomach covered. - There is a brown stain on the bottom (see photo 2). - There is a small tear at the base of the shoulder strap (see photos 3 and 4). They have been folded and stored in a cabinet. No pets, no smokers. Type...Overalls Design...Solid
