HydraPak Polar Surge Ascent Water Bottle

The tri-layer insulation system is designed to maintain a temperature differential of up to 20°F cooler than the ambient air for approximately two hours. It is best suited for shorter rides or workouts where you need a quick, cold drink rather than all-day ice retention.

The Surge Valve is self-sealing, meaning it only releases liquid when you squeeze the bottle or apply suction. It is designed to prevent spills during active use, though it is not intended to be tossed loosely into a bag where it might be compressed by other gear.

Yes, the cap is designed to split apart, making it easy to clean in the top rack of your dishwasher. We recommend hand-washing the bottle body to preserve the integrity of the insulation materials over time.

Yes, the bottle features a slim, ergonomic profile specifically engineered to fit standard bike bottle cages securely. The integrated Grip Groove also helps ensure it stays in place even when you are riding over bumpy terrain.

The bottle is constructed from BPA-free polyethylene and polypropylene, with a food-grade silicone valve. All materials are food-safe and designed to be lightweight and durable for athletic use.
