Switchnest washable swim diaper: the complete guide to the best 2-in-1 baby swim diaper

A washable swim diaper is a swimsuit designed for swimming: it doesn't swell, remains thin and stable in the water, and only contains solid waste, as required by swimming pools. Unlike disposable diapers, washable swim diapers are durable, economical, and ideal for baby swimming lessons.

At Ma Boule De Couches® , we created the Switchnest , the only 2-in-1 washable bath nappy capable of transforming into a real complete washable nappy with its Flexinest system.

Why a washable swim diaper?

Disposable diapers swell instantly in water, becoming heavy and uncomfortable. In contrast, a washable swim diaper allows water to circulate: no swelling, no discomfort, no spongy feeling.
