Frequently Asked Questions

Quick answers to common questions about kids swimwear sizing and fabrics.

What if my child is between sizes?
We recommend sizing up for longer wear and to ensure your child has enough room to move comfortably. Swimwear fabrics are highly elastic, so a slightly larger size will still fit securely.
Is the fabric safe for sensitive skin?
Yes! Our fabrics are OEKO-TEX Standard 100 certified, meaning they are free from harmful chemicals and safe for children's sensitive skin.
Do your swimwear run true to size?
Yes, our sizes are designed based on standard physical height and body measurements for children. However, children grow fast, so please consult our height chart before buying.
How do I choose between rash guard sets and swimsuits?
Rash guard sets (long sleeves) offer maximum sun protection (UPF 50+) and are perfect for outdoor beaches. Standard swimsuits are highly flexible and great for pool lessons.
