The Rift Tumbler Lid is constructed from polished Tritan and BPA‑free food‑grade polymer, featuring a VaultLoc™ twist‑lock system for a secure, leakproof seal. A spring‑loaded sip lid opens with one hand and locks firmly, while a silicone gasket prevents spills. The visual lock indicator confirms proper closure. Fully compatible with the Rift Tumbler Collection and VSSL Nest Mug, it upgrades any brewing setup or serves as a spare lid for your Rift Tumbler.
