Cayman Fitness Insulated Stainless Steel Water Bottle Review

cayman fit cayfit water bottle insulated stainless steel product photoEvery now and then you come across a product which gets straight to the point. The Cayman Fitness 17 Ounce Insulated Stainless Steel Water Bottle is an example of such a product. With no frills or extras to speak of, the Cayman Fitness bottle is a bare-bones stainless steel bottle which accomplishes everything that it needs to and nothing that it doesn’t.

Cayman Fitness makes much more than just water bottles, and this durable insulated bottle is meant to be a “go-anywhere” companion to the healthy, active lifestyle promoted by the company and their products. The choice of insulated stainless steel is certainly a great compliment to this goal, bringing to the table a bottle which is virtually unbreakable and can accompany you anywhere you go. But how well does this simple bottle stack up to some of its fancier competitors? Let’s find out in our complete review.

Personally, I’m a fan of the metallic finish on the Cayman Fitness bottle, but it might turn some people off. It makes the bottle seem extra durable, and in a way it truly is because you don’t have to worry much about damaging the finish. The bottle is solid and well constructed, yet remains quite light weight even when full. At just 17 ounces, the Cayman Fitness water bottle is ideally geared towards portability, but might be a little wanting in capacity.

Easily able to fit in just about any cup holder in your car, gym, or probably even sneaking into the water bottle holder on most bike racks, the Cayman Fitness water bottle is certainly a great option if your main concern is portability. If you want a single bottle that can tote a whole days worth of water, you’ll want to look for something bigger. But if you just need something that you can always be sure will be easy to transport and ready to provide a quick drink, the 17 ounces offered by this Cayman Fitness bottle might be just the right size.


Cayman Fitness Insulated Stainless Steel Water Bottle with Lid Off


The lid of the bottle includes a vacuum sealing technology in the form of a BPA-free plastic seal, which further improves the bottles insulation while also ensuring a water-tight, leak-proof seal. The lid pushes down and screws in, and when it is tightened properly, I can’t get it to leak at all, no matter how much I shake it. I feel confident that my Cayman Fitness bottle isn’t going to be spilling any time soon, so long as I make sure to close it properly.

The Cayman Fitness bottle has a particularly narrow mouth, which is something I’m not too fond of. It is very difficult to get all but the smallest of ice cubes into the bottle, which in my opinion somewhat diminishes the usefulness of having an insulated bottle in the first place. However, having a narrow mouth is one of the things which must be accepted in the realm of portable water bottles, as any wide-mouth will be somewhat bulky by nature.

In terms of insulation capabilities, the Cayman Fitness is equipped with the same double-walled vacuum insulation technology that leading brands rely on for their insulation capabilities. Cayman Fitness advertises the bottle’s ability to keep liquids cold for up to 24 hours or warm for up to 12.

Testing out the insulation capabilities of the Cayman Fitness, we’ve found it to be a pretty great insulator, on par with just about any top of the line insulated bottle. Since the mouth is narrow I have trouble getting as much ice as I would like into the bottle, but once inside it tends to stay pretty frosty, even after long periods.

Review Summary

The Cayman Fitness insulated water bottle is a simple design with a great execution. Ideal for anyone looking for a bottle which is durable, portable, and well insulated, the Cayman Fitness could serve gym goers, athletes, cyclists, and everyday users very well.
