If you spend time outdoors — hiking, paddling, gardening, or simply enjoying a sunny afternoon — you've probably heard of SPF. But UPF is different, and for clothing, it's the standard that actually matters.
SPF vs. UPF — what's the difference? SPF (Sun Protection Factor) measures how well a sunscreen protects against UVB rays. UPF (Ultraviolet Protection Factor) measures how much UV radiation — both UVA and UVB — a fabric blocks from reaching your skin.
What does UPF 50+ actually mean? A UPF 50+ rating means the fabric blocks over 98% of the sun's ultraviolet radiation. It's the highest rating available, and it's what every Artuforis garment is built to deliver.
Why does it matter? Sunscreen wears off, gets missed in spots, and needs reapplication. A UPF 50+ garment works all day, every time you wear it — no reapplication, no guesswork.
Who is it for? Anyone who spends meaningful time outdoors. Hikers, cyclists, paddlers, gardeners, travellers — and anyone who simply wants reliable, effortless sun protection built into what they're already wearing.
At Artuforis, we integrate UPF 50+ protection into every piece we design — because great sun protection should feel like a natural part of your wardrobe, not an afterthought.
