First off, the material and construction is fantastic. I bought these and really was excited about them. When they came, they were clean and new and nothing was wrong with them. They seem absolutely bomb proof. I'm an athletic build an have about a 30" waist. I ordered a small and the waist was maybe a tad tight but not really enough to complain as I'm sure they would've loosened up a bit. The main problem i have with these bibs is the fit below the knees. They are massive. the ankles on this bib could fit over my thighs with plenty of room to spare. Also, I'm bummed that the ankles don't zip up the leg at all for easier taking on and off of boots. Length was a little long but just how i like it. Would have kept these in a heart beat if the ankles weren't wider than the thighs.
But aside from fit, the bibs are awesome, I love the suspenders they stay well and adjust easily as well. The fact the the bibs zip off is cool too. Bomber materials and construction, nothing but the best from outdoor research. I will try my luck with another pair of bibs though.
