From product description: "The Camelbak Pro 100oz Hydration Pack is a rugged, high-performance pack designed to keep you hydrated and organized while on the job. Breakaway shoulder straps ensure freedom of movement, while the cool venting back panel and moisture-wicking straps help manage perspiration. This Pack features Camelbak's proprietary 3L Crux Reservoir with insulated tube that keeps hydration frost-free in extreme conditions. Tool-friendly utility pockets offer quick access to gear, with easy-grip zipper pulls for use with gloves. An adjustable chest strap provides stability and flexibility, and the pack's durable 1200D water resistant polyester construction withstands daily use. Whether you're a construction worker, first responder, or industrial pro, the 100 oz Pro Pack keeps you hydrated, organized, and ready for any task."
It's intended as a jobsite hydration & tool pack, but could certainly also work very well for hiking/camping.
Retailing for $110 on most sites.
I'm using Camelbak's photos since I have this product still in its original packaging (see last photo).
Shipping available for an additional fee.
I'm also selling the 50 oz. version of this for $40.
