Hydrapak Polar Surge Ascent 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

Specs:

  • Capacity: 20 oz / 600 ml or 24 oz / 700ml
  • Weight (empty): 107 g / 3.8 oz or 122 g / 4.3 oz
  • Material: BPA‑free polyethylene & polypropylene, food‑grade silicone valve
  • Maintains up to 20 °F (11 °C) temperature differential for 2 hrs
  • Dimensions: 9.2 in x 2.9 in or 10.4 in x 2.9 in 

How to Use Hydrapak Surge Ascent:

Fill, Seal, and Sip. We suggest filling it with ice on those scorching days. Pop it in a bottle cage and get going!
