Ride all day in comfort, if you can. Age and fitness has me limited to around 5 hours these days, but these pads are so comfortable you could sleep in them. I've tried lots of pads over the last few decades, but these beat everything else for me when it comes to comfort and rideability. Zero slippage once there on, just set and forget, even on the hottest of days, dripping in sweat they stayed perfectly in place, after every climb and descent. Thankfully over the last few weeks of ownership, I haven't had to test their impact protection, but I have faith that they will perform at the highest level when the inevitable happens.
