The NCW kid’s winter wetsuit is 5mm throughout the wetsuit where as many winter wetsuits are a mix of 5 and 3mm. As a result, this means ours winter wetsuit is often found to be much warmer but they still have plenty of flex because they are made from super stretch neoprene throughout the wetsuit. The special blend of neoprene we use in our kids winter wetsuit is a very soft and comfortable super stretch which we find kids are really happy to wear and gives a warm snug fit.
Kid’s Winter Wetsuit features:
• High quality “Comfort Super Stretch” neoprene for a snug and comfortable fit.
• Extra warm 5mm throughout the suit, not just the core panels.
• All seams glued and blind stitched to prevent cold water seepage.
• Duratex knee pads.
• ‘Hi Vis’ neoprene on shoulders so you can see your child in the water.
• Heavy duty YKK marine back zip with velcro zip stop and interior zipper inset seam to reduce water flushing.

Our own kids and our customers children use their 5mm winter wetsuits suits for surfing, body boarding, stand up paddle boarding, sailing, kayaking, sea swimming and more. Even when just playing around on a sandy beach in cooler weather many use winter wetsuits just because they will keep your little ones toasty warm. As a result NCW kids winter wetsuits are ideal for the cooler British climate.
Consequently, many folks call them winter wetsuits but we sell them all year round, even in the summer. We’ve certainly seen too many little ones running around the beach shivering with blue lips in the wrong wetsuit. Therefore we know many children need a nice snug thick wetsuit to make the best of fun and games at our seasides.
Children’s wetsuits can be tricky to size as kids of all ages comes in different shapes and sizes! As a result of this it is best to please measure (per diagram below) from their lower ankle (where trousers would end) across the front of the body to the lower centre neck (where a t-shirt crew neck centre would sit). The result will give you the measurement for the sizes in cm.
How to measure for a kid’s winter wetsuit

NOTE : The ages below are only a guide. For that reason you really need to measure as above to get the right fit. A sung fit is one of the most important factors in a winter wetsuit. Therefore please don’t be tempted to order your kids winter wetsuit in a size far larger than they need so it will last them longer. If the fit is loose it will not keep them nearly as warm as snug fitting wetsuit.

Measurements are for lower ankle to neck as shown above. NOT YOUR CHILD’S HEIGHT. Waist and chest measurements are also listed and what the suit will stretch to. We have used the size chart for many years and we find it very accurate. If your child is between the sizes, go for the nearest size to their measurement, larger if they are broader, smaller if they are narrow. Note these suits have LOTS of stretch.

Fantastic wetsuit. Kept my 5 year old perfectly warm in the cold winter sea today in North East UK! Sizing guide is brilliant, thankyou. Very clear and informative. Perfect fit. Wasn’t sure if it would be too restrictive being a thick 5mm but it isn’t at all; he can move around extremely well.

5 stars for these fantastic wetsuits and excellent customer service.
We bought wetsuits for our 9 year old and twin 7 year olds. They fit the children perfectly while keeping them all warm.
The children have been in the sea, rivers and lochs in the Scottish Highlands. The children have been warm and able to stay in the water for lengthy periods of time. The wetsuits have enough flexibility to be able to swim, cliff jump, paddle board and canoe without any restriction around the shoulders or legs.
The children are absolutely delighted.
Thank you for the excellent product and customer service.

We have boys aged 6 and 3 and they usually feel the cold on the beach. During our recent trip to Abersoch at the end of April they were in and out of the water all day whilst wearing these and didn’t get cold at all, meaning they had a great time and we could also relax. Very happy indeed.

Nikki ; Just wanted to get in touch. My daughter had her first nippers session in the sea last night. She received one of your 5mm wetsuits for her birthday, and wore it for the first time last night. I asked how it was, she said ‘I couldn’t even feel I was in the water. Mummy, it is awesome, you have to get one. I wasn’t even cold. I wasn’t cold at all. She feels the cold after about 10 minutes in the sea usually so this is praise indeed! I think you have a customer for life. I thought it might be a bit difficult to move in as it’s so thick, but she had no issues at all. She didn’t even feel cold back on the beach. I’ll most definitely be recommending you to others!
Thank you! Here’s to a great a summer.
