よくある質問
How does UPF fabric protection work?
UV stabilizers are integrated into the polymer melt before fiber extrusion, absorbing UV radiation and converting it to harmless heat energy. Tight fabric construction minimizes gaps where UV can pass through.
What is the difference between UPF and SPF?
UPF measures physical fabric barrier protection that does not need reapplication. SPF measures sunscreen protection which must be reapplied. UPF 50 blocks 98% of UV radiation.
