Why UPF50+ Matters — Instant Sun Protection with Clothing
By Sensibilities Team
A New Approach to Sun Protection
In a world where sun protective clothing is defined by Nylon Jackets and Polyester pants, functional options yet often heat trapping, uncomfortable and screaming "sun-gear" — we wanted something different. We set out crafting a collection soft enough to lounge in, stylish enough to wear out, yet protective enough to face the blazing midday heat.

UPF50+ — The Gold Standard
UPF (Ultraviolet Protection Factor) measures how well a textile blocks UV radiation — think of it as the fabric equivalent of SPF. A UPF50+ rating means that 98% of harmful rays are blocked. This is the maximum rating textiles can achieve, recognized globally as the highest level of fabric protection.

DID YOU KNOW?
Some fabrics acquire sun protective qualities through external chemical finishing that washes away over time. Our Stretchcosy™ Jerseys have in-built UPF50+ due to the density of its weave, and will not wear off with time.
Busting Sun Care Myths
MYTH 1: Any T-shirt is enough.
A plain white cotton tee is only about UPF 5 — letting 80% of UV rays through. True protection comes from lab-tested UPF50+ fabrics, which block at least 98% of rays.
MYTH 2: Shade keeps you safe.
Even in the shade, up to 50% of UV radiation can reach you, reflecting off surfaces like sand, concrete, or glass. UPF clothing ensures you’re protected no matter where you stand.
MYTH 3: Wet clothes still protect.
When cotton gets wet, its UPF can drop by half — sometimes as low as UPF 3. Certified UPF fabrics are tested in both wet and dry conditions to guarantee reliable coverage.
MYTH 4: Only thick, dark clothes block UV.
Yes, thickness and color play a role — but UPF-rated fabrics achieve the highest protection without needing to be heavy or dark, letting you wear lightweight, breathable pieces that still protect.
