If you ride in during the summer (who doesn’t???), there may be times when you’re putting bug repellent spray on.
DEET-based products harm synthetic fabric, so opt for a DEET-free bug spray if you don’t want any surprises.
I’ve used picaridin-based products, and they seem to work as good, if not better, than DEET.
Anecdotally, I’ve personally found picaridin-based bug sprays to work as well or better than deet for me
I also think it smells less strongly, and it’s probably safer to use around dogs.
