Before we get into the depths of sweaty summer weather, it's time to hone in on proper hydration. Doing so now means you'll be better prepared for guzzling down the ounces during the hot summer months. Staying hydrated with a Hydro Flask is magically easier than snagging a cup here and there from the kitchen faucet.

The 40-ounce capacity makes this Hydro Flask perfect for taking along to work, the gym, or the park. It's also a great companion for traveling and since spring break is upon us, this is an ideal time to snag this deal.

Hydro Flask mentions this model can keep drinks cold for up to 24 hours or it can keep your coffee warm for up to 12 hours. This is all thanks to the double-wall insulation made with pro-grade stainless steel. This material means there's no taste transfer, so you can enjoy an iced coffee in the morning and lemonade in the afternoon with the coffee taste lingering in the lemonade. The water bottle is also dishwasher friendly.

One of the worst feelings is when a water bottle leaks, so Hydro Flask ensured we wouldn't have to endure a wet tote bag by using the Hydro Flask Flex Cap, which is leak-proof.

Since the Amazon Spring Sale ends tonight at 11:59 p.m. PT, snag this Hydro Flask for 50% ASAP. Your hydration levels and wallet will be thankful for this deal.
