Product Description
Keeping sunscreen on kids all day is nearly impossible—especially on shoulders and arms that are constantly exposed. This swim shirt is designed to reduce that hassle.
The Reima Kroolaus Sunproof Shirt provides full upper-body coverage with UPF 50+ protection, helping block harmful rays during long outdoor days. The lightweight, stretchy fabric dries quickly and stays comfortable whether kids are in the water or back on land.
Why Parents Love It
- UPF 50+ sun protection – Helps reduce exposure on shoulders and arms
- Long sleeve coverage – Protects high-burn areas during extended outdoor play
- Quick-dry fabric – Dries fast after swimming to prevent discomfort
- Stretchy + flexible – Moves easily with active kids
- Lightweight feel – Comfortable for all-day wear in and out of water
Built for Real Outdoor Use
This is made for long days outside—whether that’s beach trips, water play, or outdoor school. The UPF 50+ protection is built into the fabric itself, giving consistent coverage while kids swim, run, and explore.
Things to Know
- Sun protection is strongest when dry and may decrease when wet or stretched
- Protects only covered areas—pair with hat and sunscreen for full protection
- More coverage than short-sleeve options, which may feel warmer on very hot days
Why ODSS Recommends It
This is one of the easiest ways to reduce sunscreen battles. It covers the areas kids burn most while staying lightweight and comfortable. For parents who want simple, reliable sun protection during long outdoor days, this is a go-to layer.

FOUNDED BY WOMEN. BUILT FOR ADVENTURE.
ODSS was started by mothers who saw firsthand how time outside builds resilient, confident kids. What began as helping outdoor schools equip students for all-weather learning grew into a bigger mission: Help families raise resilient, confident kids by making it easier for children to stay outside longer.
Testimonials
For us, the right gear from ODSS supports what we believe most about childhood. When children are able to be outside every day, in all seasons, they become tenacious, confident, and develop an authentic relationship with the land.

Ordering bulk with Outdoor School Shop was just as easy and seamless as I had hoped! As we open up a new program, preparing our first group of kiddos for any weather was at the top of our priority list, and ODSS came through with insight, expertise, and the coolest, most dependable gear around! Thank you ODSS!
