I've used Assos and Doc's, both very good. However, over the last year, I switch to Enzos ButtonHole Chamois Cream for two reasons, 1) a tad cheaper and 2) it works. I rub a light coating on my chamois never having any friction issues in my 3/4 hr rides. Would definitely recommend.
There are plenty of products to help with all day events or if you have sensitivity. This Enzos product has a bit of cooling effect and that works great for me (your results may vary ;^). Great product for the what it is designed for!
So I've been using this stuff for about a month and a half now and really like it. It's pretty thick and a little goes a long way. My last jar of another brand I really liked also but was a little thinner viscosity and I went through it pretty fast. Seems some people either love or hate the peppermintmenthol tingle, I don't mind it but I don't need it either, my last one didn't have it and I was fine without it. A great buy when I got it on sale so I'd definitely recommend it.
Over 30 years of riding and 20 racing, I think I've tried almost every brand of chamois cream. For years, my favorite was Assos, but I've found I like this better because better value (more for the $), slightly easier to spread and a positive bit of tingle in the private parts.
I've used Assos chamois cream for years, then tried this on a recommendation. For me, they have similar levels of protection, and there is more of this product at a lower price point. I recently completed a 102 mile, 9 hour, 11,480 ft. of climbing graveldirt ride using Button Hole, and my nether regions came out fine.
Just apply and ride. you do get a tingle at first (a plus if you like that). After that you have an excellent cream for an excellent price. it always works all the time, and is my go to cream that i buy two and three at a time when it is on sale. Excellent product!!!
