FAQ
About UPF
SPF (Sun Protection Factor) measures how well sunscreen protects your skin from UVB rays, which cause sunburn. For example, SPF 30 blocks 97% of UVB rays.
UPF (Ultraviolet Protection Factor) measures how well clothing blocks both UVA and UVB rays. UVA rays penetrate deeper into the skin and contribute to aging, while UVB rays cause sunburn. UPF 50 means the fabric blocks 98% of these harmful rays, providing excellent protection.
UPF 50+ is the highest level of sun protection available in clothing, meaning the fabric blocks over 98% of harmful UVA and UVB rays. This helps protect your skin from sunburn, premature aging, and long-term damage caused by exposure to the sun. By wearing UPF 50+ clothing, you can enjoy the outdoors confidently, knowing your skin is well-protected.
While regular clothing can offer some degree of sun protection, it varies greatly based on the fabric type, color, and weave. UPF clothing is specifically engineered to provide consistent and reliable sun protection, offering a higher level of defense compared to most regular fabrics. Here’s a comparison of the UPF value of some common fabrics:
- Crochet: 1 to 3 (Very Low)
- Mesh: 1 to 5 (Very Low)
- Chiffon: 1 to 5 (Very Low)
- Linen: 5 to 7 (Minimal)
- Cotton: 5 to 15 (Minimal to Fair)
Product and Fabric Information
Our fabric provides lasting UV protection through marine collagen peptides, which are derived from fish scales and incorporated into the fibers with nanotechnology. These peptides absorb UV rays and strengthen the fabric, giving it a UPF 50+ rating that blocks 99.66% of UVB and 94.03% of UVA rays (tested to AATCC Method 183 standards). This innovative technology ensures the fabric maintains its protective qualities and durability, even after multiple washes.
In addition to offering UPF 50+ protection, the fabric features advanced nanotechnology and marine collagen peptides for cooling, moisture-wicking, antibacterial, and odor-eliminating benefits. It regulates temperature, enhances breathability, and helps prevent odors by neutralizing bacteria, making it ideal for warm weather.
Yes, the UV protection is built to last. The marine collagen peptides strengthen the fabric, ensuring long-lasting protection even after multiple washes. Unlike chemical treatments used by other brands, our fabric’s natural UPF properties remain effective over time, backed by lab tests and real-world use.
Our sizing is designed for comfort and flexibility, with combined sizes (XS/S, M/M, L/XL). All of our designs feature adjustable ties instead of buttons or zippers, allowing for a custom fit that’s easy to wear. For the perfect fit, refer to our size chart.
