It's comfortable, and feels of good quality. I went out for a 1-hour ride and didn't feel much discomfort. It ventilates well, has good elasticity, fits well on my thick legs in size XL, has enough silicone straps, the gel cushion is very wide and doesn't get in the way.
Rockbros letters are reflective. I recommend it, I am 1.75 m tall and weigh 92 kg.
