UPF vs SPF: What the Number Means
SPF measures protection for skin you apply cream to; UPF (Ultraviolet Protection Factor) measures protection from a fabric. A UPF 50 rating means the fabric blocks about 98% of UV radiation. For a swimwear buyer, UPF is a product feature you can specify and certify, not a claim you hope is true.
How UPF 50 Fabric Is Made and Tested
UPF comes from a tight knit or weave plus, in some fabrics, a UV-absorbing treatment. We use rated base fabrics and verify with an accredited lab test on the actual production cloth, because dye and weight change the result. A garment only earns a UPF 50 label when the tested cloth passes.
Why Buyers Should Carry UPF Lines
Sun protection is a rising purchase driver for kids’ swim, rash guards, and resort wear. Offering a documented UPF 50 line lets a brand command a small premium and meet the expectations of safety-minded parents and outdoor retailers. It is also a low-cost differentiator versus generic swim.
Labeling Requirements
If you print “UPF 50” on a tag, the claim should be backed by a test report naming your product. We supply the test documentation so your labeling is defensible in regulated markets.
Frequently Asked Questions
Does UPF wash out? With rated fabrics, protection is built into the cloth and remains through normal use.
Is a darker color always higher UPF? Generally yes, but we certify the actual tested cloth, not the color.
Can any swim style be UPF? Yes, rash guards, one-pieces, and kids’ lines all support rated fabric.
Do you provide the test report? Yes, per production lot on request.
