Klean Kanteen Classic with Sport Cap

Best Stainless Steel Water Bottle

Why people love it
  • Provides the steel bottle insulation without the steel bottle taste
  • Environmentally friendly
  • Easy to clean and lasts forever

Unfortunately, reviewers report that this bottle leaks and sweats slightly. However, that's just the way it goes with steel bottles, and the Klean Kanteen has far fewer issues than most steel bottle competitors.


Features: The Klean Kanteen 27-ounce bottle features a large 1.75" opening for easy filling and pouring. Although the original version comes with a loop cap, we highly recommend you upgrade to a sport cap for easy sipping on-the-go. Additionally, this bottle is safe, environmentally friendly, and made of high-quality materials, as a result it does not retain or import flavors. It's portable, reusable, and recyclable, and keeps your beverage cool and ready for your consumption whether you're on a short hike or just using it for your daily commute. Finally, it delivers a 25-percent higher flow rate and fits most cup holders.

Durability: This stainless steel water bottle is made out of BPA-free, food-grade materials and is specially formulated using a leak-proof design. Unfortunately, as is true with anything made of steel, the Klean Kanteen can dent easily. We know that's definitely not a deal breaker, but something we thought you should be aware of. 

Color: This bottle comes in 14 different colors. Our favorites include: dragon fruit, tidal pool, and, of course, the classic stainless steel. And, most reviewers report that the colors are just as vibrant as pictured.

Size: Although Klean Kanteen carries a number of different products in a variety of shapes and sizes, the most popular is the 27-ounce. Perfect for staying hydrated all day long with just one or two refills.

Price: Depending on what color you're interested in, the 27-ounce bottle will cost you anywhere from $15 to $30. Not the cheapest on the list, but definitely a reasonable price to pay for such a well-made product.
