Polar/Hydrapak, Surge Ascent, Water Bottle Black

The Polar Surge is a lightweight, bike-specific water bottle built for fast-paced rides. Its Tri-Layer insulation combines a reflective heat shield with dual foam layers to keep drinks cool for hours, while the high-flow Surge cap delivers a steady stream and self-seals to prevent drips. The slim, ergonomic body is easy to squeeze and slides cleanly into most bottle cages.
