There's an easy way to get the comfort benefits of bibs and the ability to do nature's tasks after you suit up. Save's money over the long run also. Clip-on suspenders. Doubters will point to the tight waistband but the suspenders stretch and loosen those waistbands quickly.
A real plus over bibs is that suspenders can be adjusted easily when they stretch. Bibs require sewing. (For those of us who have objects that need real support, this can be the difference between great rides and bad memories.) It also simplifies buying shorts that are comfortable as strap length no longer matters.
Drawback is you will be one of two suspender wearers here. (There may be others but if so, the silence id deafening.)
