Hydrapak Polar Surge Ascent Black 24oz Insulated Water Bottle

When things get hot, your bottle doesn't have to.

The Polar™ Surge Ascent combines a lightweight bottle build with pro‑grade insulation so every sip stays as cool as the first. Having your fluids stay crispy cold is not only a luxury but also a performance game-changer. This bottle is akin to the other insulted options but where it stands out is the Surge Valve – a sport-specific cap that self-seals after use and simplifies the drinking process. 

Its slim, ergonomic, and bike-specific. The real gold is inside: a tri‑layer insulation system—a reflective heat shield sandwiched between two high‑density foam layers—minimizes heat transfer so your drink remains up to 20 °F cooler for up to 2 hours.

Highlights:

• Tri‑Layer Insulation: Locks in chill—no lukewarm sips.
• Surge Cap: Fast‑flow squeeze and self-sealing, no work required.
• Ultra‑Light Body: Just 107 g.
• Grip Groove: Secure hold when wet or gloved...no more dropping.
• Dishwasher‑Safe: Cap splits for easy top‑rack cleaning
