Questions?
What makes Dillos different?
We use high-performance fabrics — the same breathable, lightweight, quick-drying materials you’d expect in your own outdoor gear — but tailored for babies and kids.
The result: clothing that keeps little ones cool, comfortable, and fully sun-protected. Unlike most UPF brands, our UV protection comes from the fabric itself, not chemical sprays.
What size should I order?
Check out our size guide. We recommend using weight and height rather than the age range for the most accurate measurements.
Do your clothes have sun protection?
Dillos clothes are 50+ UPF*, blocking over 97% of UVA and UVB rays. Our high performance fabrics block UV rays without relying on chemical treatments like other brands. That means the UPF won't wash out.
*In garments with mesh vents the mesh is typically not UPF rated.
