New Saddle For Gravel Bike My existing saddle is over 8 years old and what used to be a fairly comfortable saddle has me shifting around quite a bit these days.

I am considering a leather sling saddle similar to the one made by a company with a name that starts with BR and ends with ooks.  I live in Oregon and ride all winter long in the rain on muddy abandoned logging roads.  I have fenders installed.  My current saddle still gets wet.

Would anyone happen to have experience with a similar situation and could they share how the leather held up or ways they protected the leather material?
Leather is fine to ride in the wet.  However because its an organic product you have to treat it periodically with a preservative.  Also you don't want to just leave it in the rain all the time, that will accelerate its failure.   Having decent mudguards/fenders will help reduce water up from below too.

Covering the leather with a plastic bag helps reduce absorption of water, but you can't just wrap it and forget it - that way leads to mold and tears.

The saddle needs a chance to dry out, so store the bike inside in the warm.  If that's not possible then bring the saddle inside after a wet ride.

Brooks recommend their Proofide mix which is about 15 euros for 40 grams so 5% of the cost of the saddle.  I've treated other leather goods (belt, gloves, leatherman pouch) with various mixes of beeswax for suppleness and waterproofing.
