Quick answers
• UPF applies to the areas the fabric covers, sunscreen still matters on exposed skin like face, neck, hands, and legs.
• “Sun shirt” is a common term for UPF rated tops, including rashguard style layers for water days.
• Car windows block most UVB, but UVA protection can vary by the type of glass and window. Sun protection can still matter during longer drives. Can kids get sunburn through car windows? →
No. Our UPF 50+ protection comes from the fabric itself, not from an added UV-protective spray, coating, or wash-in treatment.
Our fabrics are made without intentionally added PFAS, BPA, phthalates, formaldehyde, azo dyes, flame retardants, or antimicrobial or stain-resistant treatments.
They are also backed by OEKO-TEX STANDARD 100 certification.

Love it! We have both colours. They’re so soft, breathable and got lots of compliments from strangers of how stylish they are. The thumb holes are perfect for keeping their hands and wrist covered. The polo is perfect mix of style and function, I pull it up to cover the back of my son’s neck from the sun. And of course, the UPF 50+ protection a valuable feature!
Highly recommend!
We got two of these shirts for each of our boys and absolutely loved them! The material is stretchy and comfortable but still looks so nice! Will be purchasing more for the upcoming summer season!
As a melanoma survivor and mom, sun protection is something I take incredibly seriously for my children. I purchased this UPF 50+ thumbhole polo for my son, and I am so impressed. The fabric is soft, lightweight, and breathable, while still giving me peace of mind that he’s getting excellent sun protection during outdoor play. It’s hard to find sun protective clothing that is both functional and cute, but this checked every box for us. Highly recommend for any parent who prioritizes sun safety!
