Osprey Day-Hike Hydration Backpack

From the Amazon Listing

• HANDS FREE COOLING AND HYDRATION IN ONE PACK Stay cool and hydrated with one wearable system that combines a 2 liter drinking reservoir with a built in personal misting system. Ideal for hiking, walking, cycling, events, outdoor work, and long days in the heat.
• RECHARGEABLE MISTER WITH WIRELESS CONTROL Control your cooling with a wireless remote that lets you adjust mist output on the fly. Increase or decrease the mist based on heat, activity level, or personal comfort without stopping or removing the pack.
• DESIGNED FOR REAL HEAT AND ACTIVE USE Built for people who spend serious time outdoors, not just quick casual use. Great for trails, job sites, festivals, sports sidelines, travel, and hot weather activities where portable cooling actually matters.
• RUNNER STYLE FRONT STORAGE FOR EASY ACCESS Designed like a runner’s vest in the front with a compact day pack in the back, allowing quick access to phones, snacks, and essentials without removing the pack.
• DETACHABLE SYSTEM FOR BACKPACK OR EXPANDED COOLING USE Remove the misting system and use it across multiple setups. Transfer it between compatible hydration backpacks, or run the pack as a standard hydration backpack in cooler weather. With optional accessories like a quad nozzle kit, the system can power multiple nozzles for use on golf carts, tents, or other outdoor cooling setups.
• EXPANDABLE PACK WITH OPTIONAL WAIST SUPPORT SYSTEM The backpack includes a lower zipper connection for an optional holster waist pack add-on. When attached, it shifts weight from the shoulders to the hips while adding storage for extra water bottles and gear, improving comfort for longer use.
