I’m a big fan of carrying water EVERYWHERE I go. Doesn’t matter if it’s a long road trip or a trip to the store, I always like having ice cold water with me. The great thing about these water bottles is their ability to stay cold for so long. Throw a few ice cubes in & you’ll have cold water all day long.

Costco Thermoflask Stainless Steel Water Bottle 2 Pack

I can’t recommend these water bottles enough! Don’t forget to bring them with you when flying too! Most airports now have the filtered water stations so you can bring an empty bottle through the TSA Security check & fill it up after. This will save you $10 for that expensive airport bottled water. 1 time use of this & they will pay for themselves. These also work great as gifts too! Grab the Costco Thermoflask 2 pack & throw some goodies inside for a unique & thoughtful gift. currently has them on sale for $24.99. Save $7 and get them in store! If you can’t find them in store or want a different size/shape/color, make sure to check these out too……
