    Pretty Good, But . . .

    • Familiarity: I've used it once or twice and have initial impressions

    The top band capably maintains the legging on the thigh without feeling too tight. The calf hem is very nice - no elastic, just a flat hem. I wore this product twice - once with the thigh band on top of my shorts and once underneath my shorts. Both ways worked well, but I did find having the band on top of the shorts was more comfortable. No issues with the leggings falling down.
    I was disappointed after 5 hours riding that my thighs still showed some sun irritation. When held to the light, the material does permit rather good see-through. The fabric is very soft.
    If you are someone like me who must be vigilant about sun exposure, these are good for cloudy days or short sunny day rides. I will keep looking for a denser knit material for longer sunny day rides. I have also read UPF-rated clothing only protects from UVB rays and not UVA rays - must wear sunscreen underneath UPF clothing to block both ray types.

    Good Feel, Functional

    • Familiarity: I returned this product before using it
    • Fit: True to size
    • Size Bought: Large
    • Height: 5'10"
    • Weight: 155lbs

    I tried these on after trying out a pair of Pearl Izumi sun protectors. The Castelli fabric felt softer. The Castelli fabric also felt cool on my skin. The Castelli also has a more functional silicone strip for the thigh area to keep them from slipping. The Castelli is lighter as well. Only gave them 4 stars because I noticed a seam starting to tear right out of the box. I'll fix it before it gets worse. I am 5'10 and weight 160. My thigh is 20 inches and my calf is 12 inches. I originally purchased a medium and they were too tight around the thigh. Put in an order for a Large the same day. Hoping they fit perfect.

    Unanswered Question

    Are there different UPF or cooling qualities between the black and white colors?
