All About the DUO Range 🩲🩳

The most technically advanced swim nappy in the world 🌏

It took 4 years of hard work between one of the world’s leading virologists and Splash About to develop the DUO technology, providing the ultimate defence against bacteria, pathogens and viruses in the pool, such as Cryptosporidium -the major cause of tummy bugs and sickness-, or E.Coli.

The DUOs not only do prevent viable pathogens entering the pool, they also remove the need for a disposable swim nappy during your Water Babies lessons. 🌏🍃

How it works
So here's the technical bit...

The outer part of the Happy Nappy or Jammers remains the same -made from 1mm thick neoprene and recycled polyester-, waterproof with snug fitting leg and waist bands. These are constructed from specialist grade Lycra, durable enough to ensure it won't lose its elasticity.

The inner nappy is constructed to also be waterproof, with specialist patented silver materials embedded. This ensures that any liquids leaving the nappy must pass through the silver material, allowing it to kill any pathogens as it does so.

Solid matter is kept contained using the waist and thigh ribs of the DUO, while the silver in the under nappy helps to kill any harmful bacteria, viruses and pathogens.

What's inside

"The DUO range incorporates a biocidal product (silver (nano): CAS No. 7440-22-4) into the fabric of the lining. Silver is included as biocide to enhance the anti-bacterial action of pool water chlorine on faecal bacteria."

The Science 🔬

The Current Dilemma

Chlorine found in pool water cannot kill Cryptosporidium because it is unable to break through the tough membrane that protects it.

Tough Nut to Crack

Unlike Chlorine, Silver can break down the cell membrane leaving the sporozoites unprotected.

Working Together

Once exposed by the silver, the sporozoites are then killed by chlorine helping to control the parasite and reduce the risk of parasite entering the water.

Why choose a DUO

Choosing a Happy Nappy DUO or Jammers DUO for your Water Babies lessons offers so many benefits:

Twice as safe: featuring 2 waterproof layers for added security, the DUO does not only protect against solid leaks to the pool. Thanks to its silver lining inner layer, it also helps destroy bacteria and viruses that chlorine alone can't.

Hassle-free: as the DUO has been approved as an all-in-one Double Nappy System, there's no need for under nappies during swimming lessons, making your pool prep a breeze. Just add some biodegradable or cloth liners for even easier changing and cleaning.

Cost-effective & Eco-friendly: because the DUO is a 2-in-1 swim nappy, you won't need to purchase any disposables or nappy wraps to wear underneath, making it a more affordable option in the long run. Designed so you never need a single-use swim nappy again, reduces carbon footprint by generating less waste and contributing to keep down the number of disposables that are sent to landfills or incinerators.

Step-by-step guide
Looking after your DUO

1. If there's been a 'code brown', simply turn out the inner liner and empty any solids into the toilet. You can use biodegradable or cloth liners for easier changing and to help protect the nappy.

2. Rinse the Happy Nappy or Jammers in cold water and store it in a wet bag until you are back home. If you want to keep swimming then simply rinse the silver lining, and your little one can put it back on.

If needed, once back home you can also chuck it in the washing machine with the rest of your laundry, using a 30º cycle and non-bio detergent. Avoid using softener and try to wash full loads.

3. To dry, simply make sure the inner liner is pulled out, as that makes it easier to dry all the way through. Another drying method is to roll them in a towel and lay them flat to dry, always away from direct sunlight. Do not tumble dry or iron your DUO.
