The most common golf umbrellas are straight hand-held golf umbrellas, straight automatic golf umbrellas, and 20% self-opening golf umbrellas. Because the umbrella is very big, they tend to go for a ride. After a strong wind, the weaker ones tend to be unstable. More and more humanized design has solved this problem well. Golf umbrella cover has been improved. The common practice is to make the umbrella cover into a double layer, and then the top of the umbrella cover below is empty, and then it is on the top. It's bigger than the vent and just covers it. The upper and lower layers are stitched with a small amount of needle and thread. During normal use, rainwater cannot enter the umbrella. When the wind blows, there is a surplus top row.
