CW-XWomen's Endurance Generator Joint and Muscle Support Compression Tight Pants

Do these tights have UV protection? And can they be used in the ocean for surfing?

Can these be worn daily or will they cause harm or pressure to body?

Has anyone had an issue with the syrah color being a little sheer??? I am 5'4" 135lbs......and i will need to be sure to wear nude underwear....

What's the mmhg rating?
