What is UPF and Why Does it Matter?
When it comes to sun protection, most people are familiar with SPF, the rating used for sunscreens. But did you know that clothing can also offer protection from harmful UV rays? That’s where UPF (Ultraviolet Protection Factor) comes in.
What Does UPF Mean?
UPF (Ultraviolet Protection Factor) is a rating that measures how much UV radiation a fabric allows to reach your skin. Unlike SPF, which only measures protection against UVB rays, UPF ratings account for both UVA and UVB rays—providing a more complete picture of how well a fabric shields your skin.
A UPF 50+ rating, like the one used in Hello Shade Sun Sleeves & UV Driving Gloves, means the fabric blocks over 98% of UV rays, significantly reducing your risk of sunburn, premature aging, and long-term skin damage.
How Does UPF Work?
Certain fabrics naturally offer better sun protection than others. The level of UPF protection depends on: ✔ Fabric Construction – Tightly woven fabrics block more UV rays. ✔ Material – Synthetic fibers like nylon and spandex often offer better protection than lightweight cotton. ✔ Color – Darker and more vivid colors absorb more UV rays, keeping them from reaching your skin. ✔ Treatments – Some fabrics are specially treated to enhance their UV-blocking ability.
UPF vs. SPF: What’s the Difference?
-
SPF (Sun Protection Factor) is used for sunscreen and only measures UVB protection (the rays that cause sunburn).
-
UPF (Ultraviolet Protection Factor) applies to fabrics and measures both UVA and UVB protection (UVA rays cause skin aging and deeper damage).
-
UPF 50+ means only 2% of UV rays penetrate the fabric, while SPF 50 sunscreen needs to be reapplied every few hours.

Wearing UPF-rated sun protection sleeves & UV driving gloves is one of the easiest ways to shield your skin without relying solely on sunscreen. Unlike sunscreen, UPF clothing doesn’t wear off, sweat off, or require reapplication—making it a reliable choice for all-day protection.
