## Description

The girls' swimming suit arena Dynamo Junior, with its sporty cut, is suitable for occasional swimmers who want to train in comfort. It is made of arena MaxFit fabric, which is stretchable in four directions; thanks to its good balance of lightness, elasticity and resistance, it ensures good fit and comfort. It is the sustainable version of the arena MaxFit fabric and is made of recycled polyamide; it also has UV protection UPF 50+ and is highly resistant to pilling and abrasion. The soft fabric with Elastane content is easy to wear and ensures a comfortable fit. The wide shoulder straps and ergonomic back cut offer suitable support and an optimal fit. Made of 80% Polyamide, 20% Elastane. Lined in the front in sizes 10-11 to 14-15.

Review: Great quality, comfortable fit and perfect for regular swimming - I bought the Arena Dynamo Junior one-piece swimsuit for regular pool sessions, and it’s been absolutely spot on. The first thing that stands out is the fit and comfort. It sits really nicely without being too tight or restrictive, which is important for longer swims. The material has a good stretch to it, so it moves naturally in the water and doesn’t feel stiff at all. The chlorine and salt resistance is a big plus. After multiple swims, the fabric still looks and feels like new – no fading, no sagging, and it keeps its shape really well. That’s exactly what you want if it’s being used regularly for training or lessons. Quality-wise, it feels like a proper sports brand product. The stitching is solid, the material is durable, and it dries fairly quickly after use. It’s clearly designed for both performance and everyday swimming, not just occasional wear. Design is simple but sporty, and it offers good coverage while still allowing full freedom of movement in the water. Perfect balance between practical and comfortable. Overall, a reliable, well-made swimsuit that holds up well over time. Great value and ideal for swimming lessons, training or holidays. Highly recommended.
Review: Swimming class - Great for swimming lesson. Sizing a little small compared to Speedo, so beware. Great otherwise.

### ⭐⭐⭐⭐ Come up VERY small.
*by M***L on 23 May 2024*

My 7 year old is usually 8/9 so I got her the 8-9. That was tiny! Bought again 9-10 and she barely fit. She’s not excessively tall.
