How Can We Help?

HydroLid is the world's only patented wide-mouth insulated lid system designed to transform your standard water bottle into a high-performance hydration system. Unlike conventional bottle lids, HydroLid uses an integrated insulation tube that extends into the bottle to keep your water significantly colder for longer periods — even in extreme heat conditions.

Protected under U.S. Patent No. 11,866,230, HydroLid® is the only product of its kind. It was born from the real-world demands of firefighters, military personnel, and outdoor athletes who couldn't afford to drink warm water in the field.

HydroLid® INT is compatible with the following wide-mouth insulated bottles: Hydro Flask, ThermoFlask, CamelBak (Chute Mag), CoolFlask, Iron Infidel, and RTIC Outback. Note: Not compatible with CamelBak Thrive Bottles.

It also works with non-insulated wide-mouth bottles including Nalgene, YETI Yonder, CamelBak (Chute Mag), and Klean Kanteen (single wall).

HydroLid® EXT is specifically designed for YETI Rambler bottles in sizes 18, 26, 36, 46, and 64 oz. Note: Not compatible with RTIC Outback Jugs, YETI Silo, or YETI Rambler Jugs.

HydroLid works with a wide range of bottle sizes — from standard 18 oz to large 64 oz wide-mouth bottles. This means you can scale your hydration based on the mission: a compact bottle for short patrols or trail runs, and a high-capacity bottle for extended operations or full-day field work.

The HydroLid system is also designed to work across multiple bottle brands, so you don't need to replace your existing gear. Simply swap out your current lid with a HydroLid to immediately upgrade your hydration setup.

Firefighting environments are among the most thermally extreme conditions a person can face. Standard water bottles allow heat transfer through the lid and into the water, leading to rapid warming. HydroLid's insulated tube system dramatically slows this heat transfer, keeping water colder longer even when the bottle exterior is exposed to high ambient temperatures.

HydroLid was literally born in the fire — it was designed with first responders in mind. Whether you're working a wildland fire, a structure burn, or a prolonged incident, staying properly hydrated with cold water is critical for performance and safety. HydroLid gives you that edge.

Yes. HydroLid is compatible with Hydro Flask, RTIC Outback, ThermoFlask, and other wide-mouth insulated bottles commonly used by fire departments and emergency personnel. The HydroLid EXT also fits YETI Rambler bottles, which are widely used in first responder communities.

Rinse with warm water and mild dish soap after each use. For deeper cleaning, disassemble the components and use a wire tube brush to clean the hydration tube. Avoid abrasive cleaners, bleach, or placing in a dishwasher as this may damage the insulation materials.

Allow all parts to air dry completely before reassembling. Regular cleaning ensures optimal performance and longevity of your HydroLid system.
