Swim nappies are designed for water as they don't absorb liquid like regular nappies
Available in disposable (single-use) and reusable (washable) options
Designed to catch solids only, not urine
Essential for swimming lessons, resort pools and beach adventures
Fit snugly around legs and waist to prevent accidents
Regular nappies absorb water and turn into soggy balloons. Swim nappies contain solid waste without swelling up, so your baby can actually move in the pool. Most public pools require them anyway—they're your ticket to resort pools and beach adventures. Our nappy bag buying guide covers what else to pack.

Proper fit prevents pool accidents and keeps your little explorer comfortable:
Based on weight – Size by weight rather than age. Small typically suits 7-12kg, Medium 11-15kg, Large 14-18kg. Weight ranges vary by brand.
Snug fit around legs – Leg openings should sit snugly without gaps or red marks. Gaps allow leaks; too tight causes discomfort.
Brand-specific size guides – Some reusable options are "one size fits most" with adjustable snaps fitting 3 months to 3 years. Check manufacturer sizing before purchasing.
