This umbrella casts a lot of shade.  It has uv protection in it.  The fabric is not the standard cloth which after time fades in the sun.  It is an open weave fabric probably made from synthetic material.  It looks more expensive than the actual cost.  You must have an umbrella stand with an opening that can hold a pole that is 2.5 inches.  Must read specifications before buying an umbrella stand since most stands do not have a pole capacity big enough for this umbrella since the span is much larger that a standard umbrella.  Great purchase.
