great for on the go, the flip lid fits on all hydroflask wide mouth bottles. the flip lid makes it convenient to sip your morning coffee or tea whiling driving or walking to work. the lid helps control the flow of your beverage, preventing sloshing and spilling while you drink. we recommend that you don't get reckless with maneuvering any bottles outfitted with this flip lid, as it is not guaranteed leak proof (although i have been known to throw my 12 oz thermos fitted with a flip top in my backpack and i have yet to experience a leak).
- flip-top opening for easy access
- silicone stopper to help prevent spills
- made of durable polypropylene PP#5
- compatible with all newer styles of wide mouth bottles
