The waistband of my PI MTB shorts rides right on top of the rear pockets, but I like bibs. Glad I don't "need" the pockets, and these were on a good sale...
Work very well. Finally tried a bib, was a good sale price. No issues, bottom fits and rides comfortable. Straps do not iriate shoulders or chest. Especially useful in colder weather keeping my middle section warm and draft free.
