Wondering if a racing suit made from kangaroo is worth the expense over cow? I may have a custom suit made that will be way easier to get on and off since I'm paralyzed. There is a guy who specializes in making these and the suits use two long zippers versus one. A fellow para track day rider I know has one and speaks highly of his and even took a tumble once with no ill effects. The maker will use cow or kangaroo. The kangaroo hide will be 1mm thick and is said to be tougher and lighter than cow. Looking for feedback from those that have actually ridden wearing a kangaroo suit. Are they indeed lighter? Are they cooler to wear temp wise? How is the flexibility?
