Coolflask Review

The Coolflask 64 ounce insulated water bottle is great for your favorite beverage on the golf course. This size holds plenty of ice cold water or electrolyte supplement for those hot days.

It keeps cold for up to 48 hours and hot for 24 hours.

I would buy it again. ★★★★★

From the Coolflask website:

Coolflask’s 64-ounce insulated water bottles are made from 18/8 kitchen-grade stainless steel, and of course, they all come with lids with straws.

The 64 oz insulated water bottle is popular with backpackers and outdoor enthusiasts due to its large size, double insulation, and wide mouth.

Whether you’re looking to spend the night near the park or work out indoors, a 64 oz insulated water bottle will ensure you have plenty of water.

Note: Not for carbonated drinks. Do not put it in a freezer or microwave. Hand wash only. See care and use guide.

Why I purchased it

I normally take two bottles of water or two bottles of Gatorade to the golf course. It’s not unusual for me to finish both before I’m done with a round. In Florida, 64 oz. would not have seemed large at all.

At first I thought “This Coolflask pretty big.” Now, I’m thinking it’s always better to have more than you may need.

It cost $34 dollars. It comes in a bunch of different colors.

The Coolflask comes with 3 different style screw on lids. One is just a wide mouth handle lid. Another is an easy twist spout lid. The one I use is a flip up straw lid. It’s like a water bottle cap that is attached with a hinge.

The insulated water bottle comes with 2 reusable straws and a straw cleaner.

It has a removable insulated sleeve, is made with food grade stainless steel and has a lifetime warranty.

The sleeve has a removable shoulder strap and a hand hold strap.

One issue

The one thing I can see that may become an issue is that the lids all have a grab handle.

Why could this be a problem? While it’s not a deal breaker, I’ve seen people post photos of broken lid handles from over use or being to rough with them. .
