Its an oil to moisturize the skin. We try to ride 30 miles every week but the weather does not always cooperate. it is not mentioned that they are Velvet. Super impressed! Very snug. Okay so my first pair the sole broke two months after I bought them but Amazon as always were great about replacing them for free and I hope the second pair last longer than the first pair and it was just a fluke. I ordered my normal size of 8. It is very difficult to install even though it seem easy in the instructions. And the the Amazon renewed product was basically brand new with box and everything, love it! Bei einem zweiten weißen Kopfhörer ebenfalls, allerdings etwas weniger.
