This cream is designed to protect your skin from wet, dirty conditions. It is not petroleum based and won’t damage the fabric of your bike shorts. It is also easier to clean off with soap and warm water.
Castelli makes any effort to avoid any ingredients that can irritate the skin or damage technical cycling fabrics. Many of the ingredients are natural, avoiding any synthetic ingredients that are associated with potential health issues.
The packaging is important as well. The tubes make it easy to get an exact amount of cream and are more hygienic than jars. The 100 ml size means you can fly with the tubes in your carry-on luggage.
