35oz Leak Proof Insulated Travel Tumbler Eclipse - Nav

In this review the BruMate Nav 35oz in Eclipse is assessed as a go-anywhere insulated tumbler for people who need a large, truly leakproof cup for commuting, road trips, or long work days. The single biggest reason to consider it is the BevLockTM magnetic locking lid combined with the OctaLock thread system that aims to eliminate spills while still fitting most car cup holders and backpacks. Overall it reads like a practical choice for anyone prioritizing temperature performance and reliable leak protection.

Key Features

• Fully leakproof BevLock: The magnetic BevLock lid provides a secure, locking seal so you can carry carbonated or hot beverages without worrying about spills.
• Cup-holder friendly design: At 35oz capacity the tapered stainless body still fits most car cup holders for convenient travel use.
• Long temperature retention: BevGuard insulation keeps drinks cold for 24+ hours and hot for up to 6 hours so beverages stay at the intended temperature during long outings.
• OctaLock thread system: The patent-pending lid thread gives eight stable sipping positions and a simple twist-to-lock motion for consistent opening and closing.
• Non-slip base and finish: A silicone base prevents rings on furniture and helps the mug stay put, while most finishes are top-rack dishwasher safe for easy cleaning.

Who It's For

The Nav 35oz is best for commuters, travellers, and anyone who wants a single large mug to cover an entire day of hydration without needing refills. It suits users who value robust temperature control for both hot and cold drinks and who carry beverages in bags, cars, or backpacks where leaks would be a problem.

People who prefer a very slim travel cup or need a smaller hand-held bottle may want a different model, and those who expect absolute trouble-free lid action should note some users report occasional sticking with the locking mechanism even though others praise its durability.

Pros & Cons

• Durable stainless construction and finishes that are mostly top-rack dishwasher safe.

Cons

• The locking lid mechanism can feel stiff or stick for some users, requiring a careful twist technique to remove.
