What product do you use for this?Even though the factory straps are some of the most water resistant out there, I still wouldn't push it if you really want it to last. Pretty much any leather will eventually start to become dry and crispy with enough wet/dry cycles as the impregnated oil begins to deplete. You can prolong it's useful life with regular conditioning, which I make a monthly habit of doing with all of my leather straps regardless of brand. Just takes a few minutes to rub a little product on and wipe it off. It makes the strap feel instantly softer, but will also cause it to wear in better over time and eventually give it that warm, supple feel you get with older leather rather than just cracking and creasing in high wear areas.
