Amazon Prime Day deals may have officially ended, but don't walk away just yet. There's still time to fill your cart with last-minute deals you don't want to miss. I'm here to tell you that the post-Prime Day prices on water bottles — yes, including major brands like Yeti and Owala—are some of the best I've ever seen! As a shopping editor, I've tried all of the internet's most coveted water bottles, and I just searched Amazon to find the best ones that are still on sale and in stock.

So, what makes these water bottles so special? The Good Housekeeping Institute's Lab experts have thoroughly tested the YETI Rambler with Chug Cap and Owala FreeSip and gave both bottles positive remarks for their versatility and durability.

After testing the Owala FreeSip for over six months, Good Housekeeping Institute's Kitchen Appliances and Innovation Lab Director Nicole Papantoniou says her favorite thing about the bottle is the ability to drink from the spout like a straw or tilt it up for a bigger gulp. "It requires barely any effort to drink out of; all you have to do is purse your lips a little around the spout and use the smallest amount of pressure to get a full, smooth drink of water," she notes.

Eva Bleyer, a reviews analyst in the Kitchen Appliances and Innovation Lab, notes that the Yeti Rambler is her top overall water bottle pick for its ease of use. She explains that it's comfortable to hold thanks to its sweat-proof design, and simple to sip out of with its tapered chug cap.

Both bottles received great reviews for their insulation and leakproof designs to keep drinks at temperature for hours and prevent spills. Each are also dishwasher safe for easy cleaning. Plus, Owala and Yeti offer a bunch of splashy and neutral water bottle colors to choose from.

No matter which option you shop, these top-tested water bottles can help you stay hydrated this summer.
