Long sleeve sun rashguard swimsuit
Product description
If your child needs a practical long sleeve swimming costume for sunny days, this JiAmy one piece is a straightforward option. It combines long sleeves, UV sun protection and a comfortable stretchy fabric so they can move freely in and out of the water. 🌞 It is designed for girls aged 3 to 12 years, with a fit range that suits typical heights from 100 cm to 150 cm.
Key takeaways

This JiAmy girls swimming costume uses a lightweight, stretchy fabric blend designed to feel comfortable during summer activities. The material is made from 88% polyester and 12% spandex, helping it stay flexible as your child plays. It also dries quickly, which is useful after swim sessions or beach games when you want them to feel comfortable sooner.


The long sleeve design is paired with UV sun protection, helping to cover more skin than standard swimwear. There is also a half-zip closure, which makes it easier to get on and off without fuss. The one piece cut and soft triangle bikini bottom are made to support movement, so it works well for swimming lessons, water parties and general water play.

A key benefit is the convenient balance between coverage and comfort, particularly for active days where kids are constantly in motion. The printed pattern adds a fun look without compromising on the practical features. If you are choosing swimwear for a growing child, it can help to check the height guidance and size chart before buying.

What you’ll notice day to day

The fabric blend is built for everyday wear in warm weather, with a breathable feel and a stretchy fit for active play. According to the product description, it dries quickly and is also designed to resist shrinking, which helps it keep its shape after regular use. That matters if you are buying swimwear for frequent trips to the pool, the beach or outdoor water games.


It is also made with a convenient half-zip, so dressing is simpler before swimming lessons and easier when getting ready after. The round neck and long sleeves support a more covered look for sun and breeze, while the soft triangle bikini bottom is designed to allow flexibility and movement. This means less restriction during kicking, reaching and general play.

You also get the practical benefit of an easy care routine for keeping colours looking vibrant. The guidance is to machine wash in cool water without detergent, then hang dry in the shade to maintain the soft texture and bright print. Keep in mind that hang drying in the shade is part of the instructions, so it is worth factoring that into your routine.
It suits you if

It makes sense if you want a long sleeve, one piece girls swimsuit that offers UV sun protection and comfort for active summer use. It is a solid pick if your child is between 3 and 12 years and fits within the stated height range of 100 cm to 150 cm. It may not be the best match if you are looking for a different style cut or a swimwear type outside the rashguard one piece approach.
The half-zip and one piece design can be especially helpful when you need something quicker to dress for lessons or beach play. With its printed pattern, it also gives a fun, coordinated look for days by the water, while still prioritising stretch and mobility for movement.
