I love winter bibs!!! They make riding in cold weather a pleasure. These are very high quality and an insane value! If they fit, you should love them. I've used these winter bibs a lot. These are warm. The fleeced material goes all the way up the chest. I've used these happily down to 30 degrees (with a good winter jacket, winter gloves, shoe covers, and a thermal cap). Nice details like "Roubaix" fabric (medium thick) fleeced on the inside. This material is used in the front panels. While a lighter more ventilated fabric is used in the rear leg panels. Also, a thin flexible panel behind the knee, zipper in the front (to ease exit), sewn in labels (that wont fall off in the wash), high-quality mesh on the straps and back for breathability. The CyTech EIT chamois is excellent. De Marchi owns CyTech (also a supplier of chamois to Rapha, Assos, etc.). The endurance chamois is very soft and very comfortable and thick just under the sit bones. CONS: None that I found. Note: Due to the stirrup design (which I prefer), the ankle is a little loose. Thus I wear 9 cm Castelli black wool socks over the ankles (and booties in super cold or wet weather). Perfect. FIT: These De Marchi winter bibs fit true to size. I'm 5'10" and 185. I wear a size L in Pearl Izumi and a XL in Castelli. Here, the size L fits me perfect. ... I think the size L would fit riders who are 5'7"-5'10" and about 160-185 lbs.
