First of all, everyone should determine the quality of an umbrella based on its sun protection factor and the fabric used for sun protection. Nowadays, there is a kind of silk-like fabric on the market with a layer of transparent UV glue added, which can make the sun umbrella have good UV protection function, and at the same time, it will not affect the opening and closing of the umbrella due to climate changes.

Secondly, when purchasing a sun umbrella, carefully check the light transmittance. Since sun umbrellas are used in strong light, the perception of the human eye is very important. A sun umbrella with a high light transmittance will make the human eye feel very uncomfortable.

Sun umbrellas are consumables. They are usually used continuously for about six months each year, which is approximately two years before their sun protection effect weakens. When choosing an umbrella, you should be targeted. If you want it to look good, choose a pure umbrella. To be durable, you should choose an umbrella that can be used for both weather and rain. The firmness of the umbrella ribs is an important quality criterion for a sun umbrella. When purchasing, you can open the canopy, hold the handle, and scrape it hard from side to side to check if the umbrella frame is swaying and if it is firm and reliable.
