I purchased two of these shade sails to go on our camper since we have no openings. The quality is very good and allows for an adequate amount of light to penetrate without it being bright and unmanageable. They have Reinforced rings on the corners and sides to hold them up I got one in sand and blue I prefer the sand the blue is a very bold vivid blue.￼￼ we haven’t installed the shade sales yet as we are in the process of moving our camper to a different site.￼￼
