Hydro Flask Standard Mouth Bottle with Flex Cap

$21$35Save $14

This medium-size model comes in 18 colors, from classic neutrals to fun brights — but you'll save the most with this sleek black version.

$21 at Amazon

If there's a standard bearer for the Hydro Flask line, it's probably this 24-ounce variety. Its slim profile makes it a cinch to toss into a backpack, car beverage holder, even an interior jacket pocket. It'll keep things cold and hot for 24 and 12 hours, respectively. That's no mean feat. It features the patented Flex Strap and Flex Cap.

"I like this so much I had to get another one!" confessed a marine-minded maven who owns this model in Seagrass and Starfish. "I love this bottle not only because it’s great at keeping drinks cold or hot, but the design is SO smooth! The color? Oh my gosh, it’s so pretty! Definitely recommend."

Hydro Flask Wide Mouth Straw Lid

$25$50Save $25

Prefer sipping through a straw? Try this highly rated tumbler, which you'll save a whopping 50% on in this fun seagrass green! It comes in a bevy of other beautiful colors too.

$25 at Amazon

With over 39,100 perfect five-star ratings, this ex'straw'dinary bottle is a hit with Amazon shoppers, thanks to its large 32-ounce capacity, convenient carry loop and, of course, its super sip-able lid. Plus, it's on sale for up to 50% off!

"I've been using this Hydro Flask all day, every day since I bought it," gushed a satisfied sipper. "It keeps my water cold, is easy to clean and has survived a couple of drops, no problem. The handle is easy to hold onto and the straw makes me drink more water because it's easier to sip, rather than picking up the whole bottle. The color is cute, too."

Hydro Flask Wine Tumbler & Bottle

$19$25Save $6

This is the Carnation variety...but feel free to fill it with rosé, hibiscus tea or lavender lemonade.

$19 at Amazon

Yes, the word flask suggests clandestine booze-sipping. And, well, no judgment here, you do you, but this diminutive (at 10 ounces) vessel is also great for a wine-sipping beach confab with friends, not to mention that it will also keep your morning joe, afternoon chamomile and evening cocoa piping hot. There are eight colors available at this price.

"Love my little flask," said this all-temperature advocate. "This is the perfect size cup for travel, camping, etc. It definitely keeps my cold beverages cold and my tea nice and hot for hours. I’m so happy with this purchase!!"

Hydro Flask Oasis Water Jug

$94$125Save $31

Looking to stay hydrated all day long? This 128-ounce behemoth has you covered! It comes in classic Black as well as Rain, Indigo and Dew.

$94 at Amazon

This big boy is the one you want for a long day at the work site, a multiple-hour two-person hike or a day at the beach. With a full gallon's capacity, you can load it up straight with cold water or the bev of your choice, or chuck in some ice cubes to really keep things chill.

"This is the ultimate jug," said one happy hydrator. "I need ice water that tastes good, away from home. This jug plays three major roles. 1: Camping — ice water, all weekend for two. 2: Weekends away (hotel, for example) where you can't get tasty water. 3: Afternoon with my kids and dog at the park. They each need a ton."

If you have Amazon Prime, you’ll get free shipping, of course. Not yet a member? No problem. You can sign up for your free 30-day trial here. (And by the way, those without Prime still get free shipping on orders of $25 or more.)
