Perfect for my, jump in the cool crazy 6yr old!

My 6yr old can swim, but has never been in deep pools. He loves to jump into water and so we needed something that wouldn't obstruct his swimming, looks less like a baby aid and easy for him to put in and off, as well as allow him to do his crazy jumps into the water. This was perfect. He never took it off, could join in with the older kids and has excellent buoyancy.

Surprisingly brilliant!

My daughter (4) used her swim vest for the first time today and she loved it! She's learning to swim but still needs that additional buoyancy and this worked perfectly. She had the freedom of movement to be able to practice swimming while the vest gave her a real confidence boost in the water. Highly recommend for little ones learning to swim.

This swim vest is great. Bought one for my son who is about 16kg. He is able to paddle around independently and has the freedom of movement to practice his swimming. Even his swim teacher likes it. Dries quickly and good quality too.

Excellent product. Just what I was looking for.

So impressed with this product. It was exactly what I was looking for. My 6 year old is very confident in the water but does not have the strength yet to stay above the water. This vest keeps him above water and meant I did not hold onto him every second. So much better than armbands. Would highly recommend. Once again I put my trust in Decathalon to created an excellent product and they did.

Good quality

Revelatory! Highly recommended

Our boys loved these and they massively boosted their confidence in the water. Not suitable as life-jackets - but they gave us parents a bit more comfort too - knowing we had a bit longer to reach them if they got into trouble.

Good for little swimmers

The only thing is there is not bottor strip to fasten from underneath so the jacket is slightly sliding up when swimming, but great for little swimmers to learn swimming and does not interfere with freedom of movements.

Not a safe product

Bought this swimvest for my 5 year old son for holiday. Day 1 the strap near the buckle nearly tore right off. On day 2 the other strap starting tearing. The result being the front buckle was at high risk of just unravelling at any moment while in the water and the vest sliding off completely. Highly dangerous and was not used again. Didn’t last 2 days. Avoid. Decathlon should stop selling this product and review its quality/safety.

Great for my 2yo and 4yo boys!

Works great for my 2yo and 4yo boys in both calm ocean waters and swimming pools.

A word from the product manager

After observing the needs of children in the discovering swimming phase, we invented this new design of vest to provide comfort and ease in practice. Its simple shape envelops the torso and adapts to a child's size, while freeing the arms and shoulders for greater freedom of movement.Children using it must already be comfortable in the water because the buoyancy volume selected for this vest will place a child just on the surface to perform the first swimming movements.

Nabaiji's 3 learning to swim experiences

Nabaiji offers 3 experiences: Discovering the water, Discovering swimming and Discovering underwater. The SWIMVEST+ swim vest is part of the "Discovering swimming" experience: the children are comfortable in the water but have difficulty in floating They use their arms and legs and need great freedom of movement to benefit from their experience. This swim vest gives them the right level of buoyancy needed to let them progress and empower their swimming.

Recommendations for use

This vest is not a life vest, but a learning-to-swim vest.Adjusting to the child's size is very important to avoid rubbing on the back of the neck.For use under constant adult supervision. After use, always rinse your vest with clear water to remove chlorine, sand, and salt. Let it dry in a well-ventilated area.To avoid premature discoloration, do not leave your swimming vest in direct sunlight.

Product weight

About 8.1 oz
