How to use
Swim diapers aren’t designed to hold liquid
They’re made to contain solid messes. If they could absorb pee, they would also absorb pool water.
To avoid liquid leaks, change into a swim diaper right before your water activities, and change into a regular diaper afterwards.
To put on + remove:
Look for the ‘back’ printed on the back, then pull on like underwear. To take off, pull down or tear at the side seams; dispose in trash.
Based on local pool regulations, additional swimwear may be required to be worn over swim diapers.
Dive in to swim

There’s nothing quite as magical as seeing summer through your child’s eyes.

Swimsuit FAQ's
How many swim diapers come in a pack?
The quantity of swim diapers in each box differs based on the size. You may notice that as the swim diapers become larger in size, the number of swim diapers per pack decreases as the amount of materials utilized in each diaper increases.
Small: 20 swim diapers
Medium: 18 swim diapers
Large: 17 swim diapers
What are the materials in The Swimsuit?
The compact, plant-based core is made of cellulose, polypropylene and polyethylene. The nonwoven topsheet, backsheet, waistband and leg cuffs are made from polypropylene/polyethylene. There is a polyethylene film, elastomer, adhesives, and certified skin-safe inks. Our swim diapers are hypoallergenic and dermatologist-tested, but we recommend consulting with your doctor if you’re concerned about a certain allergen, fabric, or medical condition. Please note that we cannot say that our products are vegan because that classification is reserved for food products. In any case, our diapers do not contain any materials from animal sources. For more information, you can read our full Swimsuit Safety Report here.
Where do you manufacture The Swimsuit?
The Swimsuit is made by the same manufacturer as our classic, most-loved Diaper. The Swimsuit is made in Canada, with materials made in Canada, Mexico, and the US. We selected our manufacturing partner because of their superior technology, high quality control, and best-in-class facilities. They are also certified with ISO standards and GMP (Good Manufacturing Practices).
Is The Swimsuit recyclable or compostable?
The Swimsuit is not presently recyclable and should be disposed of in a trash or diaper bin. The process to recycle diaper materials is difficult due to two current barriers: collecting and sorting the used diapers from the waste stream, and sanitizing the diapers. The core of The Swimsuit is made of plant-based cellulose that should decompose under natural conditions.
Our focus is on sustainable material research and development, with the ultimate goal of creating fully biodegradable or recyclable disposable diapers. For more information, visit our Coterie Impact page here.
