STANLEY Quencher H2.0 Tumbler with FlowState Lid 40 oz

Lifetime-style durability with proper care and the included warranty
Key Buying Points
40 oz capacity with double-wall vacuum insulation keeps drinks cold or hot for hours, reducing refills during commutes, workouts, and trips.
FlowState Lid with three positions (straw, sip/spout, and closed) offers versatile sipping while providing improved leak resistance.
Ergonomic, comfort-grip handle makes carrying the tumbler easy during travel, at the gym, or around the office.
90% recycled BPA-free stainless steel combines durability with eco-conscious production and long-term use.
Dishwasher safe design simplifies cleanup of both the tumbler and the lid components.
Lifetime warranty provides peace of mind and aligns with Stanley’s rugged, long-lasting branding.
Narrow base design helps the tumbler fit most car cup holders, keeping hydration handy on the go.
The Catch
Not fully leak-proof when tipped or overfilled; the FlowState lid reduces leaks but does not guarantee absolute spill-proof performance.
Heavier when full, making one-handed use and portability less convenient for some users.
Premium pricing compared with budget 40 oz tumblers, which may deter cost-conscious shoppers.
Lid can be loud or clatter on hard surfaces if dropped or set down forcefully.
Some users report occasional lid-seal wear or need for thorough cleaning to prevent odor buildup in straw components.
