This must be Pearl Izumis lower-end chamois, because it is bulky and uncomfortable compared to every other pair of PI bibs I own. The bibs themselves are nicely made and do keep my knees and thighs warm on chilly or damp days.
I am a big fan of knickers. Rarely if ever do I wear a full tight, as the shins are not that sensitive to cold. And if it's that cold that I am worrying about cold shins, well, I'm headed to the gym instead of outdoors! Having said that, I am also a big fan of PI, particularly their various bottoms. These particular knicks have modest loft, a great chamois, and the best leg grippers I have experienced yet. Hopefully they will also prove durable, as have most of my other PI pieces.
