Back to school blues? Hit the halls with a Hydrojug, now 20% off on Amazon

Your kids may have already gone back to school, but in the chaos of shopping all the supplies, it’s likely you may have forgotten something.

Books, folders and notebooks are probably accounted for, but how about a water bottle?

Keeping children hydrated is key if you want them to stay healthy and focused during their studies.

According to the American Academy of Pediatrics, 5- to 8-year-olds should consume 16 to 40 fl oz, 9- to 13-year-olds should have 22 to 61 fl oz and 14- to 18-year-olds should drink 29 to 88 fl oz.

The HydroJug Sport Insulated Stainless Steel Water Bottle is a stylish solution to staying hydrated all day long — and it’s 20% off on Amazon right now, its lowest price in 30 days.

HydroJug Sport Insulated Stainless Steel Water Bottle

The reusable tumbler comes in three different sizes — 20 oz, 32 oz and 40 oz — that can easily be stashed inside a backpack. It is triple-vacuum insulated and has a copper layer to keep your drinks cold and sweat-free.

The product also features a screw-top lid, grip handle and attached straw, while a silicone base pad keeps your beverage stable.

This bottle will last a long time thanks to rust-resistant, shatterproof stainless steel. It’s made from food-grade BPA-free materials that ensure safe drinking.

Choose from 39 bold and neutral tumbler colors, including light blue, tulip, orchid, cream and berry pop.

One happy shopper wrote, “It’s the perfect size because it’s big enough that I’m not constantly refilling it, but it’s still easy to carry around and fits in my cup holder. It feels really well made, keeps my water cold for hours, and the handle makes it super convenient to take everywhere.”

Study hall is annoying enough. Stay awake and energized with the HydroJug Sport Insulated Stainless Steel Water Bottle, now 20% off for a limited time.
