I can't go into my place of business wearing bike shorts so I ride in with knee length baggy Columbia Swim shorts. They look like any cargo shorts but have mesh liner and deep pockets. Fresh underwaer rolled up in a pocket and I put them on in a handicapped stall at work. I use this saddle on my bike because the board stif saddles make no sense to me.

With this saddle I can wear much less dense/confined padding in bicycle shorts for my long weekend rides and never experience any discomfort.
BTW, my commute is 7 miles each way and I ride in 110 degree Nevada heat.
