The VSSL Rift Tumbler Lid is constructed from polished Tritan and BPA-free food-grade polymer, featuring a proprietary VaultLoc twist-lock lid for a secure, leakproof seal. A spring-loaded sip lid opens easily with one hand and locks firmly in place while drinking, with a silicone gasket that creates a tight seal to prevent spills. Fully compatible with the Rift Tumbler Collection and the Nest Mug.
