You often use parasols for UV protection, don't you?
They say it is efficient to use products that are light-colored on the outside and have black blackout lining on the inside.
I heard that since sunlight reflects off the ground, it is better to use a black lining to absorb it.
I'm also planning to use this as a reference when choosing a parasol.
