safe material:
Fiber material is made of cold material, which not only protects you from hot weather but also from all weather, and protects your skin with UV protection.
These fibers have a lifetime. Even if you wash them about 70 times, they don't lose their effectiveness.
UV protection is also very good. NoBu.gs is a UPF 50+ level that blocks 99% of UV light.
NoBu.gs can be used by all families without restrictions. I think this is a product that is very good for family health.
