50 oz Insulated Travel Tumbler with Handle - Blue Dune

Our review of the Simple Modern Trek 50 oz tumbler finds it best suited for people who need a large, durable bottle for all-day hydration. The single biggest reason to buy is its combination of sizable 50oz capacity and reliable double wall insulation, which keeps drinks cold for long stretches with fewer refills. The Trek's ergonomic handle and straw lid make it practical for commuting, long drives, gym sessions, and outdoor days when convenience and temperature control matter most.

Key Features

• Large Capacity: The 50oz volume reduces trips to refill so you can stay hydrated through long shifts or outings.
• Leak Resistant Straw Lid: Comes with a straw lid and two straws that help prevent spills and let you drink on the move with less mess.
• Double Wall Insulation: Vacuum insulated construction keeps cold drinks cold and hot drinks hot for hours.
• Durable Construction: Made from premium 18/8 stainless steel for a sturdy cup that resists dents and stands up to daily use.
• Ergonomic Handle: A thoughtfully shaped handle makes carrying a full 50oz tumbler comfortable over longer distances.
• Warranty & Design: Backed by a limited lifetime warranty and a patent pending lid design for added peace of mind.

Who It's For

The Trek 50 oz is ideal for people who need a single bottle to last all day: commuters who avoid refills, hikers or campers wanting durable insulation, and anyone who prefers sipping from a straw while on the move. The handle and large capacity make it a good fit for gym bags and vehicle cup holders that can accept a larger jug.

It is less well suited to those who need an ultracompact bottle for travel or for small cup holders; if you routinely require a very compact or pocketable bottle, consider a smaller model. Also, if you prefer a flip-top spout rather than a straw lid, this design may not match personal drinking preferences.
