Rated 2 out of 5 by from Their bottles are great, this cap is not. I purchased a standard 18oz bottle with this cap. As another reviewer has already noted, after submerging the cap while washing I discovered water trapped inside. Luckily I heard the water and did not experience soapy water leaking into my drink. I had to shake the cap vigorously to get the water to leak out from within. I would recommend getting the sport cap. Because this standard cap's hollow internal space traps water while washing I can't give it more than 2 stars. I can't imagine this is ideal for keeping the bottle sanitized and your drinks uncontaminated.

Rated 1 out of 5 by from Great bottles, horrible caps I bought two hydroflask bottles with the same standard mouth loop cap and both caps were flooded with water after the first wash. I discovered this when I went to use my bottles again and heard a sloshing sound coming from the caps. There doesn't seem to be a way to unscrew the caps to get the water out either. Pretty disappointing for the quality of the bottles.

Rated 5 out of 5 by from Good lid, just make sure it's tight. I am surprised by the reviews. I noticed I have to screw it tight so it doesn't leak. When I do, there is no problem.

Rated 4 out of 5 by from Works fine for me. Honestly, I was surprised to see all the complaints. The lid has never failed me. I use it on one of the insulated bottles and have taken it out hiking, camping, and take bring it along with me just about every day and yet to have a leak. I don't put anything in it other than water. Contents other than water HAS interfered with the o-ring seal on my other bottles in the past. Putting other contents requires cleaning much more often than just water and in my experience dry-rots the o-ring faster. I simply put water in it to keep it hot or cold for longer. If I want to drink something other than water like tea, coffee, I use instant drink mix packets and use a separate cup to mix it in. If I were to add/change anything about the cap, I'd offset the loop to the side, and vacuum seal the cap as well. I don't think the cap is vacuum insulated or insulated at all for that matter. Reason I'd like a well insulated cap is because I go camping often in the mountains no matter how cold it is in the winter. It would be awesome if my water would be just a little hotter in the morning when I wake up for a hot cup of tea or coffee. But that's being a little picky I know, so its not really a big deal. If one was made, I'd buy it immediately is all I'm saying. Guess that's why I give it a 4 star rating.

Rated 2 out of 5 by from Caps need to be re-engineered! Horrible. I like the flask itself, but i am VERY disappointed in the lids all leaking. I just got two more lids- a flat cap and flip-up cap, one for each flask i have. I thought mine were defective due to the leaks, only to find out that the new caps do the same thing. Not worth it if drinks are spilling in your lap =(

Rated 5 out of 5 by from Keeps cold thing cold and hot things hot I received a Hydroflask as a Christmas gift from my sister and her family, and I LOVE it, especially now that the hot summer months are upon us and my work does not have AC, it comes in handy.

How do I get mold off of the gasket?  What should I use?

Asked by: john17
A natural cleaning recommendation would be soaking in white vinegar then wash as normal with dish soap and water.
