We strongly recommend referring to our official Size Guide to choose the right fit for your child, especially when purchasing our Happy Nappy™ or Baby Wetsuit range.Age ranges are provided only as an initial guide—exact body measurements are the most critical factor.For the most accurate fit, measure your baby while they are lying flat and not immediately after feeding:Measure snugly around their tummy (across the belly button).Measure around the fullest part of their upper thigh.The Snug Fit Rule: When worn, you should be able to slide one finger comfortably under the leg and waist cuffs. The seals must be snug enough to prevent leaks, but comfortable without leaving deep red pressure marks.

To ensure products remain in good condition our advice is always to hand wash in cool water and dry away from direct sunlight, unless otherwise stated on the care label. We do however, recognise that soiled nappies may need machine washing now again. In this case please wash at 30° and use non-biological detergent. Frequent washing in the machine may affect the longevity of the product.

The Happy Nappy™reliably protects against leaks into the pool without the need for any other under nappy. However, we do recommend wearing a Nappy Wrap and Liners with the Happy Nappy™, to help you with changing and cleaning should an accident occur. Some UK Swim Schools do require a double nappy system. If this is the case, our under nappies should be worn underneath. A disposable nappy will also fit under the Happy Nappy if you prefer.The Happy Nappy Duo™ is recognised as a double nappy system by UK Swim Schools and requires no other nappy to be worn underneath.

The Happy Nappy Duo™ is the only swim nappy with a silver lining that kills germs from faeces within the nappy. This silver layer gives the Happy Nappy Duo™ a double nappy status required by most UK Swim Schools, meaning there is no need to buy or use any other under nappy. The Happy Nappy™ does not have this silver ion technology and is a single layer swim nappy so will need a nappy wrap underneath if this is stipulated by your childs swim school. Both the Happy Nappy™ and Happy Nappy Duo™ provide reliable leak protection with no need for any other under nappy (unless required by your swim school).

Both of our Float Vests provide the same level of buoyancy. The Go Splash Swim Vest was designed for holidays, with flat, non-removable floats, so is perfect for packing in your suitcase. The Go Splash Float Jacket has 8 removable floats so you can reduce the buoyancy as your child becomes more confident in the water. Both the Swim Vest and the Float Jacket are learn to swim aids. They are not life saving devices. They must be used under adult supervision.

Our ranges do not stop at baby swimming. We have lots of products to suit babies, children and even adults who may need incontinence support in the pool.If you are looking to move on from the Happy Nappy™ range, take a look at our Jammers collection. These offer the same faecal leak protection as a Happy Nappy™ in ages ranging from 2 years to adult.If your baby has outgrown our baby wetsuits, take a look at the UV Sun & Sea Suit or Shorty Wetsuits which are both suitable for wearing in swimming pools. Our Thermaswim range may be a suitable next step if looking to move on from our Baby Warm In One™. (Please note, none of the wetsuits for older children contain the Happy Nappy™ technology, so if incontinence support is required, this must be purchased separately)

No. Like all reusable and disposable swim nappies on the global market, the Happy Nappy™ is designed specifically to contain solid fecal matter and prevent waterborne contamination in public pools. Swim nappies are water-permeable so they do not absorb pool water and drag the child down. Always use a regular dry diaper for travel to the pool, and change into the Happy Nappy right before stepping into the water.

UPF (Ultraviolet Protection Factor) 50+ is the highest certified sun protection rating achievable for fabrics. It blocks over 97.5% to 98% of harmful UVA and UVB rays, shielding your baby’s delicate skin during outdoor swimming and tropical beach holidays.

Life Vest (Life Jacket): A certified safety and life-saving device with high, chest-focused flotation designed to keep a person's head above water automatically (even if unconscious). Required for open-water boating and marine safety.Swim Vest / Float Jacket: A learn-to-swim buoyancy aid that surrounds the child's torso to encourage a natural, horizontal swimming posture while paddling and kicking. It is not a life jacket and must always be used with direct adult supervision in shallow, controlled pool environments.
