Hydrapak Polar Surge Ascent 24oz Water Bottle Black

What Our Gearhead(R) 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(TM) cap opens with pressure and seals on its own to prevent leaks while riding.

The Tri-Layer(TM) 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.
