The Monnka Summer 2025 collections' swim diapers have been made with a special fabric that protects the skin from the sun's rays and also prevents solid leaks when the little one is bathing at the beach or pool. Sizes 0-6 months up to 7 kilos 6-12 months from 7 to 10 kilos 12-18 months from 10 to 12 kilos 18-24 months from 12 to 13.5 kilos WARNING: The inner fabric of the swim diaper prevents solid or liquid leaks when in the water, but if worn for a long time playing outside the water, it may eventually leak since the inner fabric does not absorb liquid like a cellulose diaper but retains it to prevent leaks. Features Composition: 100% polyester UPF 50+ fabric (EN13758-2 standard) Snap closure on the sides Flexible and comfortable Rinse with cold water after use Wash at a maximum of 30
