I am super glad that mountain shorts do not include liners anymore. They were terrible, just the worst. They were always shorts, and bibs are far more comfortable, and the chamois that is used in the standard mountain liner is pretty much a slab of foam sewn into a mesh brief. Maybe I wouldn't have that opinion if I wasn't riding road bibs. Road bibs were my jam, far better in pretty much every way, but this new generation of MTB specific bib liners are vastly improved and, especially when doing rides 3 hours or less, are better than many road bibs.
Things I love. There is a flap to pee out of. I didn't think much of it until I had to use it. It is simply more convenient, especially if you wear a hip pack, with these shorts I don't have to take off my hip pack to pee. With other Bib shorts they rise above the hip pack belt so you have to remove the hip pack to pull down the shorts. Not so with the Endura Bibs. The Chamois is actually situated slightly rearward. Not a lot, seems like just a few millimeters, but just enough to make up for the fact that on a mountain bike you are typically more upright than a road bike and the chamois is situated to support better. Not as compressive on my junk. Almost the same feeling as the Assos Crater Cooler, but not quite, these shorts do not compress your bits and are more comfortable because of it. These are a dedicated liner, they are noticeably thinner and more breathable than even the best road bibs and that is a major plus as things get warmer on midsummer rides. Pockets, lots of pockets. These are great for that 1-hour ride after work when you don't even want to grab the hip pack, you just want to get out for a quick spin before it gets dark. I never used the Hydration bladder compatible pocket, but I used all of the others and was happy with my experience.
If I were to complain about something, it would be the Chamois, it was great for any sub-3-hour ride, or when paired with a comfortable saddle, but for longer rides or rides on a demo bike with a crappy saddle, I was wishing for a better chamois. I was going to dock this thing a star for that, but then reminded myself that the chamois I was comparing this to were in shorts that were 2x and 3x this price and are an unfair comparison. I thought I was going to badmouth the little button snaps on the back that are designed to work with the Endura shorts, but I never noticed them.
All in all these shorts are great. I would happily pay an additional $30 to get this exact same short with an even better chamois. I know you can make that happen Endura, I know you can.
Familiarity: I've used it once or twice and have initial impressions
Fit: Runs small
Size Bought: Medium
I try and do most of my rides without wearing any sort of pack and these bib liners help me get that done.
3 pockets on the back plus the water bladder / back protector pocket along with a small pocket on the lower leg.
Chamois feels fine, and according to the size chart I should be in a Medium but I feel that might be a bit misleading. at 5'9" 175 lbs I have a 34 inch waist but felt the legs are a bit tight and the should straps could be a bit longer or more stretchy.
Once I'm out on the trail I don't notice it. My real only complaint is that I would like maybe the side back pockets to be a tick lower for easier access, I'm simply not really flexible in the arms / shoulders.
