I brought this Mares Junior Long Sleeves (UPF50+) Rashguard to my snorkeling adventure in Tioman and I loved it! It was easy to move around in and I didn’t get any sunburns.
Faezah Zahra –
This rashguard exceeded my expectations – it’s super comfy and the UPF50+ protection is a must-have for any water sports. However, the sizes run a bit small.

What’s the difference between the long and short sleeve versions of this rashguard?
Imran Hanafiah –
The main difference between the long sleeve and short sleeve versions of our Mares Junior Long Sleeves (UPF50+) Rashguard – Girl is the coverage they provide. The long sleeve version (412501) covers the arms all the way up to the wrist, while the short sleeve version (412507) only covers the upper arm. This makes the long sleeve version a better choice for cooler weather or for added protection from the sun, whereas the short sleeve version is a good option for warmer conditions. Both versions are designed to be lightweight, fast-drying, and comfortable for water sports.

I’ve tried a few different Mares rashguards in the past, but I have to say the junior cut on these ones is the most flattering. However, the material does pill a bit after multiple washes. Can we expect any improvements in this area?

The Mares Junior Long Sleeves (UPF50+) Rashguard is a staple in our water sports wardrobe. The quick drying material and flat seam construction make it so comfortable to wear. One thing to note, though, is that the seams can be a bit rough on my skin sometimes. But overall, we’re super stoked with this purchase!
Nurin Amira –
Will this rashguard provide protection against insect bites when playing water sports?
Imran Hanafiah –
Thank you for reaching out and asking about the protection provided by our Mares Junior Long Sleeves (UPF50+) Rashguard. While the UPF50+ rating does offer excellent protection against the sun’s harmful UV rays, it does not provide protection against insect bites. However, the lightweight and breathable fabric can help keep the mosquito-borne diseases at bay. For best protection, we recommend applying insect repellent before engaging in water sports. We appreciate your consideration of our rashguard for your water sports activities and hope this information is helpful.
Hanna Wong –
I completely love this rashguard! I’ve worn it for 5 swims in the past week and it still looks brand new. The material is super lightweight and doesn’t cling to my skin like other rashguards. The UPF 50+ protection is a must-have for our family when we’re out enjoying the water. Highly recommend!
