A regular cotton t-shirt has a UPF as low as 5. Every JudyP top is rated UPF 50+ — blocking 98% of harmful UV rays, all day, without reapplying.
What Is UPF — and Why Does It Matter?
UPF (Ultraviolet Protection Factor) measures how much UV radiation a fabric actually blocks. A UPF 50 rating means only 1/50th (2%) of UV rays pass through the fabric. Compare that to a standard white t-shirt at UPF 5 — which lets 20% of UV radiation reach your skin. Every JudyP style, from our tanks to our dresses, carries a UPF 50+ rating.
4 Reasons UPF Clothing Is Worth It
Counter-intuitively, quality UPF fabric is lighter and more breathable than the heavy cottons people rely on for sun coverage. JudyP's moisture-wicking, lightweight construction keeps you comfortable in direct sun — not sweltering under it.
UV radiation breaks down collagen and elastin — the proteins responsible for youthful, firm skin. A 2013 study in the Annals of Internal Medicine found consistent sun protection significantly slows photoaging. Your best anti-aging investment might not be a cream.
Most people apply 25–50% less sunscreen than needed — and almost no one reapplies every two hours. UPF clothing provides consistent, full-coverage protection that doesn't wear off, rub off, or sweat off.
Your skin is your largest organ. Protecting it consistently from early on reduces your long-term risk of sun damage, skin cancer, and costly dermatological treatments. A well-made top that protects you for years is genuinely good health spending.
