How large is the opening? Is it any bigger than a coffee cup? My husband prefers disposable bottles as sports caps allow water through too slowly..

The opening with the lid removed is about 2-1/2 inches across. The opening for drinking is a slit, not as big as a disposable water bottle.

If you are comparing to a coffee travel mug, yes the opening is bigger. I have no complaints regarding the flow of water. I have ordered these bottles three times. The bottle seals and will not leak even when turned upside down. It also has a clip, so you can attach it to your belt loops and keep hands free. I love the hands free ability to carry the bottle especially when on long walks.

The opening is larger than the coffee mug opening. Pressing the auto seal to open and tilting bottle, a person can finish the desired amount of water.

it's the standard diameter or most steel bottles, (wide not narrow thead) you may run into issues with the threading if anything. I tried this on a clone of a klean canteen and while it wasn't a perfect fit it did prevent water from leaking... buyer beware I suppose... but my toddler loves this cap, it's gotten her to drink a ton of water, and I think it's the soft rubber nipple

A regular disposable straw should fit through the opening without an issue. Hydro Flask also makes a lid with a built-in straw. Hydro Flask Wide Mouth Straw Lid, Black

It doesn't flip open but slides open. Works pretty good. You do need to make sure you thread the cap good so it doesn't leak when you drink.

It won't fit a very small opening. I have some 2 oz bottles that it fits in, but they have the same size opening as the larger bottles.

The drinking spout is 1 inch exactly. The opening without the lid is 2 1/4 inches.

Nope, it's far too wide, unfortunately. But, lifefactory bottles have their own sippy cup covers. They're hard plastic, but they work great.

I measured it. 7/16" x 1/8" opening. I've tried just about every brand out there, and these are perfect! My hubby and I both love them. Ordered a second one for him. They really do keep coffee hotter than all the others, too. We've taken them in the car and never had spill over.

I like it and wanted a smaller one. the opening across the top is about 3.5 inches. (check with your physician/pharmacist first, some pills should not be crushed and dangerous if taken that way). thanks

I don't know its dimensions but I have the 22 ounce bottle and it does indeed fit in my car's cupbolder. It actually fits perfectly. Also, I wavered about which size to get and I am so pleased that I went for the 22 ounce bottle. It holds more, of course, and it is more useful because of that. I really like the bottle but I don't bring it when there is a risk of breakage. It fared okay when it fell on wood but i would 't want to drop it on the pavement. I love the fact that there is no taste aside from the water. You will enjoy it.

I have been able to open caps as small as pop bottles, and as big as 4inch diameter. I probably could have opened larger. No problem with it.

The opening is roughly 2" wide. ice will fit but probably with the help of a small scoop or cup.

I use the .5L size to fit in a pocket for sporting events or other places where the "beverages" are expensive to purchase. Use the larger sizes for extra water when backpacking. Never had any leaking with any method of carry. I use the standard screw top sold cap, but there is the option to buy a bite valve style, no knowledge with those.

1 1/2 inches is the opening. The top screws on then to a spout ... Luv it ...keeps ice all day long .

It's like the really big wine bottle size.. not regular skinny bottle if that gives you an idea.. my fits inside opening.. It is a good size

The opening is the same diameter as any flask. I recommend an average sized funnel. Don't get anything too big as it will spill if you overflow. Most funnels with a long spout should fit. I don't have exact measurements for anything. Just Google it.

It appears to be bigger than it is, and while it's not a big opening for water, I still am able to manage and love the taste of the coffee! Just remember to put the gold filter in because a few times we forgot and had a mess on our hands, but that's the fault of brain overload. ;-)
