Thermos FUNtainer 12 oz Vacuum Insulated Stainless Steel Water Bottle with Straw Lid vs CamelBak Thrive Flip Straw Kids 14 oz Bottle with Tritan Renew
Which should you buy? Our verdict on both, pulled from our full The Best Kids Water Bottles: 7 Compared (and One to Skip) comparison.
The Thermos takes it on cold retention and on the depth of its replacement parts range, which together decide whether a kids' bottle survives more than one school year. The CamelBak is the better answer for smaller children and for households that want the dishwasher to be the whole cleaning routine.
Thermos FUNtainer 12 oz Vacuum Insulated Stainless Steel Water Bottle with Straw Lid
Buy itThe default school bottle, and the one whose lid, straw top and straw stem you can all buy separately.
- Push-button cover keeps the silicone straw sealed away from desk trays and lunchbox crumbs
- Thermos lists the straw lid, the spout lid and straws as individual replacement parts (stock varies)
- Rated to keep drinks cold for 12 hours, so water is still appealing at afternoon pickup
- Double-wall stainless steel body, described by Thermos as built for drops and rough daily use
- The straw channel needs a narrow brush regularly, even with a top-rack dishwasher rating
- Insulated steel plus 12 oz of water is close to 630 g, which a small child feels all day
- The range leans heavily on licensed characters that date fast
CamelBak Thrive Flip Straw Kids 14 oz Bottle with Tritan Renew
Buy itOne of the two lightest bottles here, with a dishwasher claim that covers the whole bottle including the cap.
- About 145 g empty, so it is under 570 g full while holding more water than the 12 oz insulated picks
- CamelBak states the whole bottle including the cap is dishwasher safe, with no hand-wash exception
- Leak-proof when closed and spill-proof when open, which suits a bottle lying sideways in a bag
- The kids' flip-straw cap is sold on its own, so a chewed spout is a part order
- Single-wall Tritan, so cold water is room temperature by lunch
- Clear and translucent finishes show every scuff and drink stain
- The soft spout invites chewing from children who chew
