This 30" golf umbrella is made with a full fibre umbrella with 8 bones.

We present the advantages and disadvantages of fibreglass and steel umbrella bones.

The main advantages of fibreglass, a newly invented material, are that it does not rust, it is lightweight and light, and then it is tough. It does not break easily.

Glass fibre umbrella bone in fact do not think that the middle of the word glass, you feel fragile, after a special process of wire drawing forming, this glass fibre instead has a very strong toughness, not rust and not easy to deform, and also very light, and the opposite of stainless steel skeleton, bulky is only one, the important thing is to use which stainless steel, if it is 304 stainless steel, although rust good, but because of the limitations of the manufacturing process, manufacturing costs are too high, such as the use of 301 below the level of stainless steel, then in a humid environment, less than a year will rust, so the glass fibre umbrella bone is the right choice.

It has two layers that are partly overlapped together, that is windproof, due to the large area of the umbrella, when there is a strong wind, the wind will go out from that gap, so as not to damage the umbrella. As for sun protection, just one layer is enough, because the profession is all about lightness.
