Beef jerky
The best all-round snack in a golf bag and the one most golfers overlook. High protein, no sugar, no melting, no mess, and it survives a hot bag for a whole season. A pouch at the turn does more for your back nine than anything sold at the halfway house. Ours is 1st Tee grass-fed beef jerky, cracked black pepper or sriracha, in boxes of 8.
Watch out: Check the sugar. A lot of supermarket jerky is glazed and lands closer to a candy bar than a protein snack.
