    • If you’re serious about drinking more water…
Color: Dark Green Size: 64 Ounces
I’ve gone through a lot of water bottles over the years, and this one honestly surprised me. The 64 oz size is perfect because I’m not constantly refilling it throughout the day. I use it at work, in the gym, and when I’m out running errands, and it keeps my water cold for way longer than I expected. The straw lid is convenient, and I like that it comes with multiple lid options depending on what you’re doing. The carrying sleeve is actually useful too—not one of those accessories that just gets thrown in a drawer. The extra pockets are nice for keys, earbuds, or small items. The bottle is definitely large, so if you’re looking for something compact that fits every cup holder, this isn’t it. But if your goal is staying hydrated without refilling every few hours, it’s worth it. Build quality feels solid, the finish looks good, and it doesn’t feel cheap. So far, no leaks and no complaints. If you’re serious about drinking more water, this is a good buy. ... show more

Really happy with this water bottle. The half-gallon size is great for keeping me hydrated throughout the day without constantly refilling it. I love having three different leakproof lids, especially the straw lid for drinking on the go. It keeps drinks nicely chilled and feels sturdy without being too awkward to carry. A practical bottle for the gym, work or days out. ... show more

    • Great bottle! If you don't have a nickel allergy.
Color: Samurai Cyan Size: 64 Ounces
First thing's first: I think this bottle is great. What I'm saying here is generally not a criticism. The material is listed as Stainless Steel. It takes some digging to find that it's 18/8, which means it's an alloy with 18% chromium and 8% nickel. I didn't realize this, and after using the bottle for a couple of days I had developed a really nasty cough that is still with me (greatly diminished) over a week later. Now to the rest of it. The straw lid is not fully leakproof, but it is very resistant to leak and doesn't leak quickly. The other two lids I had no issue with. All that really means is if you're gonna store the bottle sideways, don't use the straw lid. The insulation is very impressive. It was still cold after 48 hours after the bottle sat in room temperature, and after several hours sitting in an unshaded car on the hottest day of the year so far (118F heat index). Probably the biggest thing to keep in mind before purchasing is the handle. Mine hasn't broken, but many others are saying theirs has, and I can tell it's fragile. It's very nice that it comes with a straw cleaning brush, and the bottle sling is nice though the pocket doesn't really hold a phone unless you're willing to really cram it in (and I have to assume doing that a few times will cause the stitching to break). The strap is okay. ... show more

    • Your Search for the Best Water Bottle has Ended
Color: Samurai Cyan Size: 64 Ounces
I am so pleased and impressed with this water bottle! I had originally purchased it to keep in my car kit for emergency breakdowns in the hot Texas summers, but I ended up loving it so much that I now carry it everywhere. The bottle is high quality and comes with a variety of different lids. I’m currently using the lid that has a threaded cap and carry ring. The cap is threaded on the inside, which is genius, because the threads stay cleaner and you never have to “search” for them when screwing on the cap (great for fumbling fingers in the middle of the night). The cap screws on tight. Other lids have options for straws or “wide mouth” storage. The carry case serves different purposes. As a coozy, it further insulates the bottle. Because it’s fabric, it keeps the large bottle from loudly clunking when setting it down and also protects from dings and scratches. The strap is a lifesaver on this half-gallon version, and I love that the pouch has multiple pockets! I’ve used them at work for pens, mints, etc. The bottle size is incredible - basically one fill in the morning lasts me most the day. I love a well-designed product and this delivers on every count. I’m already thinking about purchasing a few more for camping and travel. I’ve owned TONS of water bottles over the years, and this is easily my favorite. Not even close. ... show more

    • "Beautiful color, excellent performance—just a little on the heavy side!"
Color: Turquoise Size: 40 Ounces
⭐⭐⭐⭐☆ I really like this water bottle overall. The turquoise color is beautiful, and it keeps my water cold for a long time just like it promises. I also appreciate that it comes with multiple lids, so I can switch them depending on what I'm doing. The only reason I'm giving it 4 stars instead of 5 is because it's a little heavy, especially once it's filled with water. That's probably the tradeoff for good insulation, but it's still something to be aware of if you carry it around a lot. Other than the weight, I have no complaints. It's well made, looks great, and has become my everyday water bottle. ... show more

    • Love it so far, best long-lasting cold drink canister for my long shifts.
Color: Turquoise Size: 64 Ounces
In love with it so far, perfect for my carry-on drink refill container. Keeps ice for over 24hrs. Perfect for my long delivery shifts, cuts stop times more than in half- gotta only stop once throughout the day. Appearance is sleak and vibrant defined coloring. Easy to use and grip. Easy to clean and leak proof from my use so far. ... show more

Color: Magic Black Size: 40 Ounces
It is awesome!! Keeps water cold...still cool after 2 days! The size is large but great for my use. The over-head/shoulder strap is a terrific plus for me as I walk with a walker and need my hands free. My first outing was our July 4th street party. Had COLD water all afternoon & evening! 🎇🎆
