I have the 32oz one and love the light weight and slimmer profile than my other 32oz hydro flask. However, this thing really scratches easily without the standard powder coating they do.

Not dishwasher safe if that matters to you. That's one reason I prefer yeti products, they're expensive but they're dishwasher safe across the board.

I like this one cause it's a little lighter and can actually fit in cup holders compare to the regular one. I use this one as my going out flask and keep my normal one for home use.

The difference is with yeti dishwashing is within warranty. With hydro flask trail series it is not. The risk is repeated dishwashing cycles may breach the vacuum seal. Yeti uses thicker metal, which makes it more dishwasher safe but heavier. Hydro flask uses thinner metal so it has a higher risk of damage in dishwashers.

$31 dollars for a water bottle? go to any Thrift Store and buy last years $25 bottle for $2.

Take it home and wash it with cheap scotch and rocks …. and thank me in the morning.
Why do you think it's in the thrift store in the first place?
I'd get a new one below $20 as it's personal water.

I haven't seen this go for sale in the past. This has been a great alternative to regular Hydro flask in terms of weight and how excellent the material feels upon touch (personal preference).

You ever drink a glass of water at a 5 star restaurant ? Do you think they throw the glasses away? Do you drink municipal water? Some municipalities recycle drinking water from sewage.

Go ahead a get a $20 mug, I'll get a used like new for $2 and a bottle of cheap scotch.
