First, I trust Leatt’s tech, products, and reputation though I don’t have lots of experience with their bicycling gear (for off-road motorcycling I do have a set of their Z-frame knee braces and tried an armored shirt that I actually liked, but that did not fit me well).I bought these because my aging (61) self is taking up mountain biking again after 20 years away from it. Past experience has taught me I’m definitely going to fall, so now that I’m old, I want any protective advantage I can get. These looked to fill the bill and after inspection I have to say that I think they will be great. I have just put in one relatively short ride on these guys and they exceeded my expectations for comfort and coolness. The weather was relatively warm, and I was not in the most ventilated overshorts, but my naughty bits stayed pretty comfortable. I have read reviews where some people feel like the chamois is too far forward in the seat, but I didn’t find that to be the case. The hip/thigh armor seems sufficient to prevent/reduce bruising, which is all I expect. Looking forward to putting them to the test on real trails.The design of these shorts is pretty impressive. It looks to me like Leatt put a lot of thought into the materials and construction. Only drawback I see so far is they expect you to hand-wash them. TBH, I’ll probably put them in the washer, but in a laundering bag. I do the same for my armored motorcycling shirts, etc. and that has worked out fine.Update 11/06/2023:I’ve worn these liners a number of times now. I continue to believe that they offer good protection, though I wish they had a bit more armor coverage. They are also very comfortable (for the most part) and seem to keep things fairly cool down below. So my one niggle with comfort is the chamois in my copy has kind of a “mold defect” that results in a small raised area, almost like a seam, that interacts negatively with my taint. This is only a problem on a longer ride, say over 10 miles. If I go much over that, I really can’t wait to get them off. Once they’re off, I’m fine. I still like these liners a lot, and I choose them over any others I have, if they’re clean. I like them so much I’ve ordered a 2nd pair.
