hiking, biking, backpacking, running
Keeping yourself hydrated while enjoying the outdoors is important. Camelbak was the first to make these ingenious items (a water-filled day-pack) ā but now many other brands exist and the price has come down considerably. Even make them with a slot for a frozen pouch to keep water cool now.
My Camelbak MULE has lasted 20 years, and still working great ā so Iām sticking with it. The zippers still function perfectly, which is more than I can say for my tent zippers.
