FAQs
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. If you're between sizes, we recommend sizing up — babies grow fast! If you're still unsure, feel free to drop us a line at info@dillosclothing.com!
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.

We hope you and your little one love your order — but if something’s not quite right, we’ll make it right.
