These knickers are thick and toasty in the cold but surprisingly comfortable even when the weather warms up. The fabric wicks really nicely, so I don't get sweaty inside. The interior is really soft and all the seams are well constructed to be gentle on the skin. The exterior is tough - I skidded out on dirt/gravel in these without the slightest hint of damage to the fabric. The waistband is wide and comfy and makes these knickers super flattering - none of that pinched muffin top look we ladies love so much. The chamois is also nicely non diaper-esque considering the comfort it provides.
The only thing I don't dig about these is that with the thickness of the fabric, the folds become a little irritating behind my knees on a long ride.
The sizing works great for me, but probably wouldn't for everyone. The legs seem slim compared to the waist size, and the bottom is tight on my small calves. If you have big cyclist thighs or calves (kudos to you, you're probably stronger than me), this probably isn't the fit for you unless you have some hips to hold these up in a larger size . I didn't find them to run as small as I thought the Capo brand might. I wear a small in other non-Euro brands and wear the small size of these, too.
