100% UV CUT & 100% SHADING

Your reliable companion for outings in scorching heat
The secret is its completely light-blocking fabric

Parasols have become an indispensable item for combating the increasingly harsh summer heat. U-DAY's All Weather series are dual-purpose umbrellas designed to block 100% of UV rays and sunlight. In tests using an artificial solar lamp, a temperature difference of approximately 34℃ was recorded after 30 minutes with and without the umbrella, demonstrating its high heat-shielding effect. Furthermore, the fabric is waterproof and UV-cut treated, achieving the highest UPF rating of 50+. With a wide range of sizes and designs available, you're sure to find one that fits your lifestyle.
