Hydro Flask  Lightweight Wide-Mouth Vacuum Water Bottle with Flex Chug Cap - 16 fl. oz.

Bottles that are too tall or too skinny flip out of the pockets on our hip packs and running vests. These are an ideal form factor. Also the screw caps seal very well and are unlikely to leak. The bottle insulation is great but the outer cap lacks insulation. It’s also black, so it absorbs the heat from the sun instead of reflecting it. Bottles that are held at an angle in a pack, keeping the liquid in contact with the cap, are especially likely to quickly warm. The double screw cap is less convenient than a flip cap as it takes two hands to open or close. Also attempting to unscrew the smaller cap sometimes inadvertently unscrews the larger one.

[This review was collected as part of a promotion.] I use hydroflask water bottles exclusively for the following reasons in order: 1) the smooth metal drinking bottle lip that your mouth touches, with no spiral grooves on the outside to touch your lip (standard mouth size) 2) the smaller bottle diameter 3) the lighter bottle weight The new 16 oz bottle, pertaining to this order, attracted me for the light weight, and bottle diameter. Sorry to say that you have killed it by putting the plastic drinking cap on it. The original artistry of the perfectly shaped metal lip has been lost. Appreciating the smooth metal lip each time I sipped made your product a pleasure to use. If I have to settle for drinking out of a plastic top I no longer need to buy your Hydroflask brand. Your original Hydro Flask Trail Series Ultralight Titanium bottle (21 oz. ,standard mouth) solved all of these priorities beautifully. Please bring it back! I am 65 years old and appreciate ergonomic shapes for comfort. People like me are an important demographic to cater to. Don't abandon the good thing you had!

[This review was collected as part of a promotion.] Everything is right about this bottle! It is light, love the smaller opening, love the color, and it holds just the right amount of water for me. Plus it fits nicely in my computer bag. Thank you!

[This review was collected as part of a promotion.] Lightweight with solid temperature control. Slightly less effective for hot drinks. Top can be just a little tricky.

[This review was collected as part of a promotion.] Lightweight, perfect size (16 oz) and dual cap makes drinking without drizzle easy.
