Review: Perfect! - There is nothing I don't like about Ecovessel water bottles. I like the company and what they stand for, I like the quality and look of the product, I like the features, I like how it holds up against other brands. This is my first Ecovessel bottle and it is completely leak-proof (after traveling a lot through vastly different altitudes and pressure changes). It holds 24 ounces, which means it doesn't have to be refilled as often as typical 2-cup bottles, and it is better quality than my last water bottle brand (which starts with a T and is 3 letters long). I put in cold water and a few ice cubes at the beginning of my trip and as long as the water I put into it was reasonably cool (chilled, cold tap, plastic bottled water that had been sitting in the car but wasn't hot yet), it stayed below ambient temperature up until the very tail of the 6-day trip. Some people have complained about the strap that attaches the cap, but I am not sure why and had no issues with it. The removable strainer and silicone bumper on the bottom are nice features, but the bottle won't fit in a typical car cup holder with the bumper on, so it's nice that it can be removed. The lid/neck size is not compatible with other brands, so don't count on switching them around. It would be nice to have a snap cap or a straw lid that didn't leave the mouthpiece exposed, but the twist cap works just fine and I'm really grateful to have a bottle that keeps my drinks out of contact with plastic (at least while it is in the bottle).

### ⭐⭐⭐⭐⭐ Cold!
*by W***Y on May 25, 2026*

Durable. I like the smaller diameter. Fits better into my travel backback. Keeps water cold! Easy to fill and clean. I like the screwoff drink spout to keep it secure. Caution: the rubber foot falls off easily.
