Insulated water bottles are awesome because they don’t sweat on the important documents on your desk and keep your water cold for longer in the summer heat. Plus, they are not as bulky or heavy as a traditional Thermos so you can take it with on with you hiking or on day trips. Here is what to look for in an insulated water bottle and the best insulated bottles on the market today followed by reviews of the best insulated water bottles.
How to Pick an Insulated Water Bottle
Actual Size of Bottle
Because insulated water bottles have a double wall they are larger than bottles that hold the same amount of water. For example, the .5L CamelBak Eddy insulated bottle is the same size as the .75L CamelBak Eddy non-insulated bottle. If you’re looking for a bottle of a particular size (like to fit in your bike bottle holder) I would recommend the .5 CamelBak or a Thermos brand bottle. CamelBak also has a Big Chill 25 ounce bottle made especially for fitting in bikes and is made of BPA-free plastic.
Bottle’s Liquid Capacity
Like above, because of the double wall construction of insulated bottles, the liquid capacity is less than you can get with a similarly sized bottle. Thermos has some good, large bottles: choose from a 34-ounce or 26-ounce insulated water bottle. Eco Vessel has two 25-ounce stainless steel insulated bottles, one with a flip straw top and another with a screw cap. Just know that many insulated bottles only hold 15-18 ounces – which is fine for when you’re sitting at your desk, but ideal for when going for a hike.
Type of Material and Where Manufactured
Unfortunately, as we’ve covered extensively while talking about stainless steel water bottles, there are no stainless steel bottles made in the US. They are all made in China. So, if you want an insulated stainless steel water bottled that’s not made in China you may have to buy a plastic water bottle – just make sure it’s a BPA-free water bottle. Another option is to buy a glass water bottle. (And if you’re new to this site we highly recommend that you buy stainless or glass because they are safe water bottles that are not made of BPA, a hormone disrupter, which is found in many plastics.)
Straw or No Straw
When I first started reviewing stainless steel water bottles I didn’t like straws in my water bottle. I’m not sure why exactly, but my personal preference was to have no straws. Now, I love my CamelBak glass Eddy water bottle and, lucky for me, CamelBak also offers a stainless steel insulated water bottle with a straw. As I mentioned above, Eco Vessel is another great choice for an insulated water bottle with a straw. I particularly like straws for work and driving because it prevents water dribbling down your shirt.
Another option is to purchase an insulated carrier instead of buying an entire new bottle. (These are made of neoprene and like a beer coozy.)
Best Insulated Water Bottle
These are the best insulated water bottles (based on either my testing or Amazon reviews) on the market today. Let me know in the comments if you’ve tested any and what you think.
Insulated Stainless Steel Water Bottles
CamelBak Eddy Insulated Stainless Steel Water Bottle
CamelBak was one of the first to make stainless steel insulated bottles. The insulated Eddy is a little smaller than some other bottles, which allows it to easily fit in car cup holders and in most bike holders. It’s their traditional Better Bottle with bite valve so if you already have a CamelBak and like the straw, this may be your best bet. You can pick one up for $24.
Eco Vessel Stainless Steel Bottle
Eco Vessel makes a 25-ounce insulated bottle designed for hot and cold beverages and costs about $20. They also make an insulated bottle with a flip straw top and a non-insulated filtered water bottle.
Thermos Insulated Water Bottles
Thermos has a number of highly rated stainless steel bottles – the Hydration (18 ounces, $17) and the Nissan Hydration (26 ounces, $30), and the Nissan Briefcase Bottle (34 ounces, $22). The Briefcase Bottle is the largest capacity of any of the insulated bottles on the market.
Thinksport Insulated Bottles
Thinksport makes a 750ml and a 350ml insulated water bottle that is double walled and one of the more attractive bottles on the market. However, it’s reviews on Amazon are slightly worse than some of the other bottles.
Glass Insulated Water Bottle
If you’re in the market for a an insulated glass water bottle, this one might be just what you’re looking for. Sun Tea’s Double-wall Thermol Travel Mug glass bottle, holds 18 ounces of liquid, and has a screw-on cap.
Plastic Insulated Water Bottles
The Big Chill 25 ounce bottle is a 25-ounce, BPA-free insulated plastic bottle that fits in bike bottle holders.
