The Chill-Its 5156 Low-Profile Hydration Pack provides on-the-go hydration with premium features such as accessory storage and padding for all-day convenience and comfort. The 3.0L (3000mL) bladder features a wide DualCap for easy no-spill filling with water or ice. Both the pack and tube are insulated to keep water cool in the heat. The antimicrobial bite valve with cover protects against contaminants for clean all-day drinking. The lightweight and low-profile design is comfortable for wear both on and off the worksite.

The pack itself is made with durable 600D water-resistant ripstop polyester for protection in rough conditions. A zippered top keeps the bladder secure while also preventing dirt and debris from getting into the pack. Breakaway hook & loop shoulder straps safely detach to prevent the pack from dangerously snagging.

The premium features of this pack include foam padding on the shoulder straps, plus venting on the straps and back for all-day comfort. For additional storage, it includes a small zippered compartment with headphone port, 6 d-rings and daisy chain webbing for clipping carabiners or other gear. A nickel-plated storm drain increases ventilation and keeps the inside of the pack dry. Reflective accents enhance visibility at night or in low-light conditions.

The water bladder can be thoroughly cleaned using the Chill-Its 5159 Hydration Pack Cleaning Kit (sold separately). The Chill-Its 5051B Bladder Replacement and 5050M Mouthpiece Replacement are also available for those needing additional/replacement bladders or bite valves.
