Perfect water bottle!

Majid ShojaeiNovember 7, 2025

Great product, light weight and looks elegant. Keeps the water cold for a long time and I’ve been carrying it around everyday for a while now and definitely enjoy using it. Read more

Love this bottle!

Wanda NeumanOctober 7, 2025

Love this! The wide mouth makes it much easier to wash than the other HydroFlasks. I love that it's lightweight. It really makes a difference. I left mine in a rental car and couldn't get it back. Even though I have several other insulated HydroFlasks and other good bottles, it was worth the money to replace this one. The Tourmaline color is somewhat darker than it appears in photos. I got one in Serpentine (dark green) for my son. Both colors are very attractive—subtle but not boring. Read more

A high-quality, stylish bottle that works great.

Steven YangSeptember 22, 2025

The Hydro Flask 32 oz Lightweight Trail Series with Wide Flex Cap is a solid choice for all-day hydration. It holds a good amount of liquid for one day, and while it’s taller than expected, it’s lightweight, leakproof, and easy to carry thanks to the flex strap. The slim diameter and smooth yet grippy surface make it comfortable to hold without slipping. Performance is excellent—drinks stay hot for up to 12 hours and cold for up to 24 hours as advertised. The only downside is that it dents easily if it hits a hard surface, so you’ll need to handle it carefully. It’s also hand-wash only. Dimensions: Height 12 1/4”, Base 3 1/8”, Opening 2 1/4”. Overall, a high-quality, stylish bottle that works great, as long as you’re careful with it. Read more

Better finish and dimension

JCNJAugust 27, 2025

We buy mostly this brand. Hydroflask is always reliable in keeping liquid hot or cold for a long time. This version is even better as it is very lightweight compared to the regular/previous models and the finish is metallic which makes it more appealing. I like that it is tall and skinny as it can fit better in backpacks and travel gear. Read more

★★★★☆

Nearly perfect

K. IshiharaJuly 22, 2025

Nearly perfect for what I bought it for—to take on runs when it is hot. Very lightweight, even lighter than the so-called lightweight and similar sized plastic Yeti I also bought, and keeps things cold for the 1-2 hours I need it to. Downsides, it is not dishwasher safe due to the finish, and is also slick when wet so I had to buy a grip for it. It doesn’t sweat, but I do when running. I also prefer the chug cap so that was extra, but equally lightweight. Read more

Beautiful Finish - not dishwasher safe!

Karli HDecember 16, 2025

I LOVE this water bottle! The color is so beautiful and the size is just right. I ordered a chug cap separately to make it easier for what I plan to use for it. I unfortunately didn’t catch that this isn’t dishwasher safe. My other hydro flasks wash just fine in the dishwasher and I didn’t think anything of it, until the wash was over and the finish mostly washed/burned off. So sad, as I am not one of those people that gets new water bottles all the time. I would have loved to enjoy the beautiful finish longer, but I will continue to love this water bottle even with the dull finish and burn marks. Just don’t make the same mistake I did! Read more

★★★★★

Best water bottle ever.

Laura MoonOctober 3, 2025

This is the perfect water bottle for me. It keeps water cold for more than 24 hours. Ice fits in the wide mouth easily. I really like the color - wasn’t quite sure from the picture. Doesn’t leak - I laid it down on my meditation cushion many times over the course of a retreat - never a drop spilled. 100% recommend this water bottle. Read more
