【Broad Compatibility】Designed primarily for Hydro Flask 32 oz & 40 oz Tumblers and the Yeti 30 oz Rambler, this lid offers a secure seal. Its universal 3.7-inch design ensures compatibility with other popular smooth-rim tumblers like Ozark and Mossy Oak (not for narrow or threaded models)
【Smooth Rim Fit – No Threads】Designed specifically for smooth-rim tumblers without threads. The lid presses securely onto a clean, flat cup edge. Please note: It will not fit threaded or screw-on cup openings. Always measure your tumbler's inner diameter (3.7 inches / 9.35 cm) to ensure a perfect Fit
【Premium & Safe Material】Crafted from transparent, food-grade SK silicone that is BPA-free. This high-quality material is flexible, durable, unbreakable, and dishwasher-safe for effortless cleaning, while the clear design allows you to check your drink level at a glance
【Leak-Proof & Comfortable Sip】Equipped with a soft, contoured silicone nozzle that provides a comfortable, leak-proof seal. The included straw can be trimmed to fit different cup heights, making every sip easy and convenient—whether you're at home or on the go
