Brand New Design Bottle from Polar Water Bottle!
Designed for mountain bikers, gravel grinders, and all weather roadies, the Breakaway Muck Insulated water bottle features a Muckguard™ cap cover that protects the Surge™ valve from whatever the trail dishes up. The high-flow Surge Cap provides a sip or blast of water and self-seals to eliminate spills and splatter, even on your bumpiest rides. Tri-Layer™ insulation and radiant heat reflective technology keep your liquids cool twice as long, so you can stay cool on long and dusty days in the saddle.
Made in USA.
