Flex Air Max Chamois for the Win
"The Flex Air Max cushion in the Long Haul seems to be the answer to my discomfort on 30-70 mile road rides (3-6 hours). I also tried the Grand Touring but didn't find them as comfortable. I'm 5'6", about 150 lbs. , and ordered Large which fit well. I tried the XL first (reviews said to size up for compression) but found the gap in the rear waistband to be annoying. I was worried about no padding on the edges of the chamois but it worked for me. My pain is in the crotch near the nose of the saddle, and that's where there's padding, along with the main seat area."
