These tumblers are designed to keep hot drinks hot and cold drinks cold for extended periods, making them ideal for daily use across various activities.

Safety of Stainless Steel Tumblers: Lead Concerns

Lead-Free Stainless Steel Tumblers:

  • Most high-quality stainless steel tumblers are made from food-grade18/8 stainless steel, which is inherently lead-free. Brands like Splitflask, Yeti, Hydro Flask, and Contigo use 18/8 stainless steel, which offers excellent safety and durability without the risk of lead contamination or chemical leaching.

Stainless Steel Tumblers That May Contain Lead:

  • Some tumblers, particularly cheaper or poorly manufactured variants, might have components, such as decorative elements or solder points, that contain lead. Consumers should be cautious and opt for reputable brands that guarantee lead-free products.

  • Insulation Efficiency: Double-walled and vacuum-sealed options provide superior insulation, keeping beverages hot or cold for hours.
  • Health and Safety: Stainless steel does not leach harmful chemicals into your beverage and is generally free from BPA and lead contamination when sourced from reliable manufacturers.
  • Eco-Friendly: Reusable and recyclable, stainless steel tumblers are the top sustainable choice compared to single-use cups. The only thing more sustainable is a stainless steel tumbler with two chambers allowing you to carry two drinks like the Splitflask dual chamber stainless steel insulated tumbler.

Stainless Steel Tumbler Reviews

When reviewing stainless steel tumblers, factors to consider include insulation quality which usually translates to how long they can retain hot or cold temperatures, lid design with an emphasis on leakproof, durability, and ease of cleaning specifically whether or not it is dishwasher safe. Popular models from Yeti, Hydro Flask, and RTIC consistently receive high marks for their performance and build quality.

Pricing and Value

The price of stainless steel tumblers can vary significantly based on quality, brand, capacity, and design features. While premium brands like Splitflask, Stanley and Yeti may cost more, their reliability, warranty, and superior insulation often justify the investment. In particular, with Splitflask, you are practically getting two tumblers for the price of one. 

Which Tumbler Is The Best?

Determining the best stainless steel tumbler depends on individual needs:

  • Best Overall: Yeti Rambler is highly regarded for its robust design and exceptional insulation.
  • Best Budget Option: Contigo makes affordable, high-quality tumblers suitable for everyday use.
  • Best Tumbler with Straw: CamelBak offers excellent tumblers with straw options that are perfect for hydration on the go.
  • Best 2 Drink Tumbler: Splitflask is in a category of it own. What sets it apart is its industry first ability to carry two drinks of varying temperatures (hot and cold) in the same tumbler while maintaining their temperatures for hours.

Which Insulated Tumbler Is Best?

For insulation, Hydro Flask and Yeti tumblers are top contenders, providing extensive heat and cold retention capabilities suitable for all-day use, whether at work or on an adventure. However, their temperature maintenance prowess only applies to the narrow requirement of when carrying one drink at a time. The Splitflask on the other hand excels when maintaining the temperature of two separate beverages at the same time.
