Hot or Cold, Hold Perfectly. The Unbreakable Promise.

Introducing the Vacuum Tumbler​​ – where cutting-edge engineering meets everyday elegance. Crafted with military-grade 304 stainless steel, this double-walled cup uses ​​scientifically optimized vacuum insulation​​ to create an airless chamber between inner and outer walls. This thermal barrier blocks heat transfer by conduction and convection, locking in desired temperatures for up to 12 hours for hot beverages like coffee or tea, and an astonishing 24 hours for cold drinks like smoothies or iced water.

​​Uncompromised Durability​​
Forged from premium 304 stainless steel (food-grade and rust-resistant), the tumbler withstands drops, dents, and daily wear. The copper-plated vacuum layer boosts thermal efficiency by 40% compared to ordinary tumblers while preventing condensation – no more wet table rings or clammy hands.

​​Designed for Life in Motion​​
The leak-proof sliding lid with silicone seal guarantees zero spills in bags or cup holders. Its lightweight, ergonomic curve fits comfortably in hand, car seat pockets, and bike mounts. The polished finish resists fingerprints and stains, maintaining sleek aesthetics through years of use.

​​Sustainability Embodied​​
Ditch single-use plastics! Each EverLock™ Tumbler eliminates thousands of disposable cups over its lifetime. The materials are 100% recyclable and BPA-free, ensuring your drinks stay pure without toxic aftertastes.

​​Perfect For:​​

  • Morning coffee warriors needing enduring heat
  • Gym-goers demanding ice-cold hydration
  • Parents needing spill-proof kid cups
  • Outdoor enthusiasts tackling extreme climates
  • Eco-champions reducing plastic waste

​​Why Settle Less?​​
While competitors claim “insulation”, our third-party lab tests prove EverLock™ outlasts others by 30% in thermal retention.
