Pretty good, not quite elite
"Firstly, the Bn3th MTB liners are my favorite liners on the market having tried a great deal of the competition. I would describe my riding preference as endurance, adventure, but performance focused, so a ton of big days on the gravel and XC MTB. I've tried a huge number of bibs across Rapha, Pearl, Castelli, and others. I think these are nice and probably something a mountain biker transitioning to road or gravel would enjoy. My reasoning for only 4/5 stars is that 1, there is a little too much fabric going on in the front of the bibs which holds moisture. Secondly, the fabric is solid, but overall doesn't feel particularly premium 'second skin' type of level, and the fit is a little loose in the corners around the pouch zone which gets a little uncomfortable on longer rides despite the pouch itself working great. Chamois is comfortable as expected. I'm 6'2 180 in a size large and find the fit is probably about right despite the looseness in the corners."
