I rarely remember to take the time to review things, but I just wore these for the first time today and am in love! I looked for a long time for the right surf leggings since I'm fair-skinned and have a history of skin cancers. Learning to surf means long days with my legs out of the water, and I didn't want to worry about getting burned constantly in the non-wetsuit months. I absolutely adore these pants - they are so comfortable and didn't even bother me in the 90+ degree heat. I could wear them all day, and no burns even after 3-4 hours in the midday sun! For reference, I'm 5'6" and 135lbs, and purchased a medium. Will definitely be purchasing at least one more pair...thank you Hurley/Nike for an amazing product.
