This is a tried and true way to ensure you don't get chafing in the sensitive areas. Especially for the long days in the saddle 100 miles, but also for short rides if you ride more than a couple of time per week.
having been prone to dry skin and saddle sores for years, I've finally found something cool and soothing that may actually be good for me. Started using this year and great so far. I prefer riding in warmer weather on rides lasting 2 to 4 hours. Stuff holds up well through the entire ride. Glad I found it!
I've been using Zealios sunscreen for about a year now and am reluctant to try anything else. It goes on really easily and dry, and does not leave my oily after application. Most sunscreens make me too slimy for on the bike use, and are generally not enjoyable to use, but I've found Zealios to not even be noticeable once on. As far as actual sun protection, it seems to do the job since I don't get sunburns, but not sure if it's any better than anything else that is out there.
Doc's Saddle Ointment shouldn't be mistaken with actual chamois cream, because it's not. But it is fantastic to use post-ride to prevent and sooth saddle sores. I use it in addition to Doc's chamois cream, particularly when I'm putting in 10 or more hours a week, and this helps prevent issues with saddle sores. Also, the smell is an added bonus. My only complaint is that it is a little bit greasy, but is worth it for the benefits.
