Review: If you’re serious about drinking more water… - 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.
Review: Coolflask - 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.

### ⭐⭐⭐⭐⭐ Great bottle! If you don't have a nickel allergy.
*by A***T on July 29, 2026*

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.
