Camelbak Arete Sling 8, Black

I bought this for my kids for travel (9yo & 11yo boys), so they could carry a water bottle, sunglasses, deck of cards, etc. I may borrow it from them on occasion, since it's more functional than my Osprey Daylite sling. Love that it fits a 24oz Stanley Aerolight comfortably, while still being able to accommodate all the essentials. I tested it out with 24oz insulated bottle, medium wallet, keys, sunglasses in hard case, sunscreen, 1st aid kit, brush, hand sanitizer, chapstick, AirPods, packable grocery bag & phone. It also fits a 1. 5liter hydration pack for hiking, although I didn't test it filled, but seemed to still have good capacity. If you need to loosen the strap, the mesh pocket (which fits an iPhone 11Pro in silicon case) shifts pretty high on your shoulder, so becomes more awkward to access while wearing. The strap can switch to either side, so my lefty kids can switch to their preferred side. My only recommendations, the key leash could be a little longer & the “secure” inside pocket is hard to get my medium sized wallet in/out. A zipper that went end to end would be easier with maybe a clip & loop to secure it. I like the external clip that secures both the water bottle from falling out and the front zippered pocket from theft. We'll be road testing this in a few weeks at Yellowstone hiking.
