As Expected from Hydra Flask
Needed to replaced the Super Sparrow one that my kid lost in camp and great water bottle as expected from this brand. Ended up buying two other Hydra Flasks in addition to this one considering the price was alot less than other retail stores. Overall, quality product that I anticipate will hold up well and will withstand beatings from active kids. Would upload photos except it looks like this function is no longer working at all.

It’s ok. But not too
[This review was collected as part of a promotion.] It’s ok. But not too great for kids as they’d need to unscrew to drink from the bottle. Easy to carry.
