So all of my bags i use, including the "sunday bag" for practice, have a designated spot outside of the bag for gloves. NEVER bunch them up and toss it in the bag. That will leave it a crusty ball from hell.
I typically get around 5 to 10 rounds out of one glove. If they are FJ, then 3 to 5. Titleist / TM / Callaway tour gloves 6 to 10. Costco, no joke, their kirkland brand gloves hold up amazing! I recently was on a trip to Scotland and was POURED on when we played 2x. I used the same glove on all of our rounds, including the rained on rounds. Let it dry properly and it's still GTG. If you have a Costco membership, it's a great option for 3x gloves at $25. Can't beat it.
