Redefine your hydration experience with the Beneunder LC131, a masterpiece of lightweight engineering designed for the modern adventurer. This isn't just another water bottle; it is a high-performance thermal vessel crafted to be so light you’ll forget it’s in your bag. Whether you are trekking through mountain trails or navigating the urban jungle, this tumbler provides the perfect blend of portability, durability, and temperature control.

Key Benefits

Featherlight Portability:** Weighing approximately 220g, this tumbler is engineered to be lighter than most modern smartphones. Its "palm-sized" design ensures it fits comfortably in your hand or small bag compartments without adding unnecessary bulk.

Medical-Grade 316 Stainless Steel:** The interior is constructed from food-grade 316 stainless steel, offering superior corrosion and oxidation resistance compared to standard bottles. It is specifically designed to handle acidic or alkaline beverages without metallic aftertastes.

Advanced 6-Layer Thermal Locking:** Featuring a sophisticated 6-layer vacuum insulation structure, the LC131 keeps your drinks at the optimal temperature. It maintains heat above 65°C and cold below 8°C for at least 6 hours.

Seamless Hygiene:** The inner liner utilizes a one-piece stretch molding process. This seamless design eliminates internal crevices, making it incredibly easy to rinse clean and preventing the buildup of residue or bacteria.

360° Leak-Proof & Quiet Design:** Engineered for active lifestyles, the lid provides a total seal for worry-free storage at any angle. Additionally, the base features an upgraded, thickened silicone pad to minimize noise and prevent slipping on smooth surfaces.

Care & Safety

Thanks to the high-quality 316 stainless steel, the interior is "rinse-and-go" for most beverages. For deep cleaning, use a soft bottle brush and mild detergent; avoid abrasive scrubbers that could damage the seamless liner. While the exterior is durable, hand washing is recommended to preserve the finish and the integrity of the 6-layer vacuum seal.
