HydraPak Polar Surge Ascent 24oz Water Bottle

What Our Gearhead® Experts Are Saying:"I'm always impressed with how cold this bottle keeps my water—even on long summer rides. The squeeze is super easy, and the cap doesn’t leak or require fuss. It’s my go-to bottle whether I’m climbing pavement or rolling dirt."We don’t hit the trail or road without a Polar Surge Ascent 24oz Water Bottle tucked in our bottle cage. It’s that sweet spot of capacity, chill retention, and ergonomic design that delivers mid-ride hydration exactly how we need it—fast, cold, and never messy.Crafted for smooth, high-flow sips, the Surge™ cap opens with pressure and seals on its own to prevent leaks while riding. The Tri-Layer™ insulation keeps water cooler for hours, and the slim profile means a secure fit in nearly any bike frame. When it’s time to clean, the cap disassembles easily so we can rinse, dry, and get back to rolling.
