Plus-One - 8 ounce Bottle with Belt Loop Holster

I've added two of these to my Camelbak hydration pack for long runs. At first they seemed really uncomfortable as my forearms kept hitting the bottles with every step. Then I realized the bottles were designed to be put in their holsters so that they curve *outward*, with the cap tilting in TOWARD your body (the opposite of what the picture shows). After I flipped them around my problem was solved! So if you find these things hitting your arms and being really annoying, try turning them around before complaining loudly to your boyfriend who swears he doesn't have the same problem with his, and insists you are crazy. Good product, especially for the price here.
