Common questions
Why do kids' cotton pajamas fit so snugly?
US rules require children's sleepwear to be flame resistant unless it fits snugly. Cotton pajamas are cut close to the body to meet that rule without chemical flame retardants.
What does OEKO-TEX mean for kids' clothes?
OEKO-TEX Standard 100 tests finished textiles for a list of harmful substances, with stricter limits for baby items.
Is organic cotton better for kids?
It is grown without synthetic pesticides. For kids with sensitive skin, dyes and finishes matter as much, and GOTS limits those too.
