Marcus & Marcus: Reusable Swim Diaper (Whale-L) [6-12M]

Let your little one splash and play with confidence! Our soft, reusable swim diaper is designed to keep pool and beach days worry-free—no leaks, no mess, just happy babies and happy parents. Made from high-quality 1.5mm neoprene, it’s durable, snug, and gentle on delicate skin.

1: What size should I choose for my baby?
Refer to our size chart based on your baby’s weight and age. Our swim diapers have stretchy, adjustable elastic cuffs for a snug yet comfortable fit.

2: How do I wash and care for the swim diaper?
Rinse immediately after use to remove any chlorine and prevent damage. Can be cleaned with soapy water. Avoid using fabric conditioners as they can affect the diaper's absorbency. Air Dry. Hand washing is recommended for best results. Machine wash with max . temperatures 40C / 104F. Wash the product before initial use. Do not bleach, tumble dry or dry clean. Store product in a dry place. Do not leave products in direct sunlight or near a source of heat.

3: Is this swim diaper leak-proof for pee and poop?
It’s designed to contain solid waste (like all swim diapers, as required by pools). For urine, the water-permeable neoprene allows it to pass through—this is normal and keeps baby comfortable.

4: Can my baby wear this under a swimsuit?
Yes! The slim, flexible design fits neatly under most swimwear.

5: Does the neoprene provide sun protection?
While it offers some UV resistance, we recommend additional sun protection (like rash guards and sunscreen) for extended outdoor play.

6: How long will one diaper last?
With proper care, the high-quality 1.5mm neoprene ensures long-term use, ideal for multiple seasons or siblings!
