I absolutely love the 64oz marathon bottle! Why? Simple because of how I can completely take it apart to clean. I hate how on some bottles you can't remove the silicone (I'm guessing) liner in the lid and how it can build up debris but with the 64oz bottle you can take it off and fully clean the cap and silicone (again guessing) liner for a fully fresh clean! I didn't really care for the fedex shipping only cause it seemed to send it 1/2 way across the country by plane and I think truck the rest of the way which seemed odd.

Thank you so much for the detailed feedback! 😊 We’re really glad you’re loving your bottle. We also appreciate your note on shipping. We’re a San Diego–based company, and sometimes carriers like FedEx route packages in ways that aren’t always the most direct, but we’re always working to improve the experience. Thanks again for your support it means a lot to us!

Excellent quality. The only thing that I'd change would be the infuser. It should've been all metal instead of a metal/plastic hybrid. Also, it should've been a little longer to reach closer to the bottom of the bottle.

Love using the pouch for my wallet or phone. Water is kept nice and cool especially for this hot summer.

I did a lot of research and found this water bottle (CrossFit Chill Brew 64oz) to the one I was looking for. I specifically like the locking mechanism on the cap and the infuser. I chose this specific bottle due to the features. Highly recommended.
