Protection against sun exposure.
What is UV Protection Wear?
UNIQLO's UV Protection is wearable sun protection that instantly blocks 90% of UV rays and an easy addition to your daily UV protection routine. These sun‑protective styles are designed to help minimize exposure to ultraviolet rays during everyday activities using specially engineered fabrics.
How UV Protection Works
UV Protection fabrics are designed to reduce the amount of ultraviolet radiation that passes through clothing and reaches the skin. This is achieved by fabric density, yarn structure, and surface treatment, which help block or reflect UV rays before they penetrate the material.
Two Mechanisms of UV Protection Functionalities
The fabric absorbs UV rays.UV-blocking treatment on the fabric prevents skin exposure.
The fabric reflects UV rays.UV protection is achieved by incorporating UV-reflective materials into the fibers.
What is UPF?
UPF (Ultraviolet Protection Factor) indicates how effectively a fabric blocks UV rays. A higher UPF rating means greater protection. Many UNIQLO UV Protection items are rated UPF 50+, which is the highest category of UV protection for apparel.

UV Rays & Your Skin
Sunlight includes different types of ultraviolet rays that can affect skin in different ways. UV‑A rays penetrate deeply and are present year‑round, while UV‑B rays are more intense and primarily responsible for sunburn. UV Protection clothing helps block both types, reducing direct exposure during everyday wear.
UV Protection clothing blocks both UV‑A and UV‑B rays.
