Ok, this product truly did save me a lot of pain and suffering. Rode the 24-Hour Mountain Bike Race, twice and made the mistake during my 1st lap of forgetting to apply my Chamois Butt'r on my Riding Shorts Liner. Big mistake as the sensitive areas quickly became raw and red causing me to sit the next couple of laps out. This is so easy to use, washes right off and creates a lubricating barrier between your gear and the parts that matter and your bike that get a lot of the friction caused by aggressive motion. Doesn't have any smell and doesn't stain. I will NOT ride without it. Period. Have a plentiful supply of it readily available. The small travel packets are awesome too as you can carry a couple in your Hydration Pack and if you need a touch more during a longer ride, it's just enough.
