Using the One Bottle Hydration System and Platypus Big Zip in the Grand Canyon

My hydration plan:
I'm not an expert, but here's what I did. I used one very old 3-liter platypus big zip bladder I already owned.I tested it on several of my training hikes and it still works perfectly.
I bought a One Bottle Hydration adapter for a smart water bottle.
I put water with electrolytes in the bottle and plain water in the platypus.

Great job on dialing in your gear and your training, so that you could have such a great Rim2Rim!!
