This awesome bottle goes great with my titanium all- road bike. Of course they 're cashy, but worth it to go with my dream bike.

Expensive. But worth it. No more plastic taste on my rides. Keeps cold for long rides in Florida too.

Expensive: Yes Stylish: Yes Quality: Off the scale These bottles are amazing. The price is off putting, but try to not let it. The lock action is smooth and drinking is effortless.

5 Jim
Ingesting plastic while drinking from a bottle in the sun is no joke. Spend the extra money and buy either the titanium or steel bottles. Put your health in front of your wallet.

What else can I say. They live up to the name. I got the new pink 18oz cup. Thought it would fit better in car cup holders than the next size up. It works for car cup holder. Note: doesn ’ t fit kids booster seat cup holders,

This is my favorite Yeti out of several that I own. Love the straw that is included and that I can close the top so germs do n't get inside the straw. I never have issues with the straw getting clogged.

Nice size bottle for daily use. Vivid blue color is easily identifiable. Sturdy and held up well on a week long mission trip. No leakage and easy grip for carrying and holding. Definitely recommend for a smaller sized bottle.

Great value for the money! My daughter uses this often and even in 90+ degree weather the water on it stays ice cold. It ’s also pretty durable. It has fallen on concrete a few times and it has held up nicely.

We got this water bottle for my very active 8- year old son. He found the simple design very appealing and it kept his water cold all day. I find it easily cleanable and that it doesn ’ t make water taste weird. I also love that the spout closes flat for sanitary reasons.
