poor heat regulation

I love the design of this and I ease of use of the lid, but it doesn't keep hot coffee hot for longer than about 90 minutes or so. and that is without opening the lid. I have an 8 year old microlite that still keeps coffee hot for about 6 hours. I had higher expectations for a hydro flask if you make your hot beverage to take with you and drink it all in under 2 hours, this would be fine for you.

Leaks

[This review was collected as part of a promotion.] Hydroflask has disappointed me. I can't seem to have a bottle that doesn't leak.

Rube Goldberg inspired top

The 16oz bottle is the right form factor to fit securely in the pockets of many packs. Bottles that are taller or skinnier tend to fall out. The cap, however, is disappointing. To open it I need to hold the bottle in one hand while I pry open the flip part of the top. That’s annoying when I’m holding trekking poles or driving. I might as well have a screw top. The flip to top is unexpectedly heavy. It’s almost twice as heavy as the lightweight version of the simple “flex cap,” and considerably heavier than even the chug cap. Like the chug cap, the flip top is not insulated. The flex cap, by contrast, is insulated. Perhaps the worst aspect of the design is the complicated lever which opens and closes the sip port from the bottom of the cap. While it’s effective, it needs to be disassembled for cleaning. Besides the bother of disassembly and reassembly there’s the chance that a part is lost or not replaced and the mistake is not realized until liquid is running out. The flex cap, by contrast, has no parts to remove for cleaning. Some years ago Hydro Flask did have a very simple, very lightweight flip top. It had a plug on an arm that was manually pushed into an opening in the cap. It usually worked reasonably well but was not secure enough to be placed inside a pack. It seems that a similar top, with the addition of a locking lever, would work very well without adding so much complexity.

Color not the same

It wasn’t the same green as the picture. It looks more blue.

Ok, Fussy lid

Purchased for air travel - lightweight and good size for carry-on, but the lid leaked when placed on its side. The bottle will fully seal if the gasket is properly in place and the lid tightened but it’s not a simple task, as REI’s video shows. My bottle from Pur is larger and much heavier, but in all a better product.

One of my go 2’s…….

Love the lightweight design and the top. I love to carry a smaller bottle - it’s so handy. Also handy to fly with.
