Hydrate on the go! The Breakaway Muck Insulated Bottle from our friends at Polar Bottle is just the bottle you need to fit into your bike’s bottle cage. This soft sided bottle is designed with a special surge valve that allows you to control whether you get a sip or a slug of water depending on how hard you to squeeze the bottle. It self seals so you won’t get any leakage, plus the attached Muckguard cap protects your drinking tip, keeping it fresh and dirt free. The bottle has tri-layer insulation and radiant heat reflective technology so your water stays cool twice as long on your ride. How cool (hee-hee, pun intended!) is that! Choose from 3 volume sizes (12 ounces, 20 ounces, or 24 ounces) and a variety of fun colors. The next time you’re getting ready for your ride, remember the Polar Bottle Breakaway Muck Insulated Bottle for cool hydration!
