How to Swap to Non-Toxic babies & kids swimwear:
Here's how to swap to non-toxic babies & kids swimwear:
What to know about baby & kids swimwear
Swimwear sits directly against your child's skin, often for hours at a time, in water and sun. Most conventional swimsuits are made entirely from synthetic fabrics and may be treated with chemical coatings or dyed with synthetic dyes that can leave residues against sensitive skin.
- Kids' skin is thinner and more absorbent than adults', so the materials in their swimwear deserve extra attention.
- Welpr looks at the fiber content, dye type, and whether fabrics are free from PFAS, BPA, and other chemical treatments.
Review the swimwear you already have
Check the tags or product listings for your child's current swimsuits. Look at the fiber content, any finish or coating claims, and whether the brand shares details about how the fabric is made.
- If the label says 100% polyester or nylon with no mention of dye type or chemical-free processing, it's worth looking into a cleaner option.
- Prioritize replacing swimwear your child wears most often or for the longest stretches, like a go-to rash guard or daily swim lesson suit.
Get more out of current swimwear safely
If you're not ready to replace swimsuits right away, a couple of simple steps can help reduce what sits against your child's skin.
- Wash new swimsuits at least once before the first wear to help remove residual dyes and chemical finishes.
- Rinse swimwear thoroughly with fresh water right after each use, and have your child change out of wet swimsuits as soon as they're done swimming.
Choose cleaner swimwear
Look for swimwear made primarily from natural fibers like organic cotton or hemp. When stretch is needed, a small percentage of elastane or spandex is fine as long as the brand confirms it's free from PFAS and BPA.
- Choose brands that use low-impact or plant-based dyes, avoid azo dyes, and hold certifications like GOTS or OEKO-TEX® — but also share clear details about their materials and production.
