A chamois for 13 cm wide sit bones perched on a road bike. This chamois is wider than the brief style chamois. The med is snug on my 53 cm thighs but not uncomfortable.

I was hesitant to order the Montcham chamois in size medium, as I've gained a few Covid lbs and am between medium and large in other clothes brands. I was mostly looking for a chamois that came down lower on my thighs than the CR Drift mediums I've been wearing the last couple years. My Drifts have been drifting up into my groins causing me discomfort, so I figured they were maybe stretched out and that new chamois were in order. I was really surprised when I opened the Montcham box - they are not nearly as long as I expected. They also were not nearly as snug as I expected. I wore them in Moab this past weekend and thought they were okay but I definitely still had to occasionally drop trou on the trail and pull them down out of my groins. So I'm a snitch disappointed, but maybe I should be disappointed with my thighs more than the chams - perhaps I've lost muscle mass due to being old as dirt.

Really comfortable chamois. Like the lower cut waist, the main fabric is really breathable and the chamois sits comfortably. Fun print as well.

I am very satisfied with these shorts. Although I usually wear mediums in padded shorts, I ordered small and they fit a tiny bit snug, but not uncomfortably. I am 5’1” and about 114 lbs. I ride close to 50 miles each ride, a few times a week, commuting and delivering food, pulling a trailer. I am in the saddle nearly 5 hours and these shorts keep me comfortable all day. I also love the feel of the thinner material, great for warm weather. I will definitely get more of these.

So, I know these chams are constructed for mountain biking, but after trying some expensive touring and road shorts from various manufacturers and being disappointed, I keep coming back to the Montcham. Even though I'm riding the hoods on a road bike, I still find this liner to be better at preventing numbness and discomfort than the $140 shorts I got at a women's-specific website. Now, instead of spending a fortune on lined shorts that leave me numb after 10 miles, I'm using Montchams under a normal pair of spandex bike shorts and riding for two to three hours in pretty good comfort. Hoping to get a gravel bike next year, so I can try them out on rougher terrain.
