Rated 1 out of 5 by from Moldy gasket Bought my first hydroflask to replace a thermos i lost. Even though I was diligent in handwashing it several times a week, it still had a moldy smell. I realized that water was getting trapped underneath the gasket thus growing mold. Disappointed that there are no maintenance instructions for cleaning the gasket as I thought the gasket was built into the lid and not removable. Also, since it is removable, hydroflask should offer instructions how to remove or sell removal accessory tools. I had to remove with thin knife and paperclip. Other features of the lid are good including handle. I originally bought wide cap for ease of cleaning...

Rated 3 out of 5 by from Great cap, but the seal stains easy Great bottle and the cap works well. I use it everyday as my regular drinking water bottle. I do add drink mixes, and they have caused mold to form in the lid. Once mold forms in the cap, it stains the seal, and can't be removed. The seal needs to be replaced in order to get rid of the stain. The cap comes clean with no issues. I bring my own water into work and refill this bottle one time each and every day, so it gets emptied at least 2 times every weekday. I have sanitized the seal several times, and just reused it. Today I again tried to clean it, and ended up damaging it in the process. I arrived on this site looking for a replacement gasket, and thought I would share my experience.

Rated 1 out of 5 by from Please come up with a solution I have many hydro flask products: -true pints, 22-oz cups, the 21-oz bottles (with sports and standard lids), 40-oz wide mouths (original lid), and two 64-oz (the newest, and previous versions that use wide mouth lid) They all work great! I used to think that the bottles were retaining the smell but it turns out that the LIDS are the problem. all the lids I have for my hydro flasks retain smell and mold. I have bought many extra lids and they cannot be cleaned either. the plastic seal came off one of my lids and I threw it away to get another one. There aren't any helpful tips on cleaning instructions. I have tried everything to clean my sports cap, standard, and wide mouth lids but they all have a sticky mold-like substance on them that is IMPOSSIBLE (even with a mascara applicator brush) to clean! -provide a video or something please...

Rated 1 out of 5 by from Leaks and does not keep water hot I have two 40 oz HydroFlask insulated water bottles and discovered this cap seal comes apart when hot water in the container. I was hoping to use these insulated water bottles for winter hiking in the White Mountains, NH. As a result of the leaking lid, hot water leaks out of the container, leaks hot water over my back and then freezes bottle to the backpack. I have tried several times to reset the seal in the lid but continues to come apart and leak. The lids are adequate with cold water.

Rated 4 out of 5 by from Easy to Carry Love this style lid because it makes it so easy to carry on a hike or walking! Can also attach a carabiner onto it and attach it to a back pack of other pack! You do need to wash frequently as mold can gather in the corners of the lid. Good product overall.

Rated 1 out of 5 by from can't clean well My 14 year old daughter uses this hydroflask almost everyday. Even though I wash/rinse it every morning and refill it because the hydroflask is almost always wet it gets mold growth inside the cap and it's impossible to clean inside the deep grooves. Since this is such an expensive product I would expect it to be made better so that you can completely clean it.

Rated 5 out of 5 by from Absolutely amazing [This review was collected as part of a promotion.] This Hydroflask wide mouth cup is so good, the stainless steel no-sweat design is awesome. On hot days it keeps my cold beverage of choice super cold for hours and on the chilly mornings I love to put my coffee in it and it will stay hot for hours as well. This is great for anyone on the go as it has a convenient little handle attached to the lid for carrying, it fits perfectly in the side pocket of a backpack or diaper bag and even the side pocket of my laptop bag. It doesn’t spill when tipped over at all. This is a great quality cup and is my new go to brand for all my beverage needs! Love this

Rated 3 out of 5 by from great until rubber ring falls out Love the wide mouth bottle and the cap is very functional. However, once the plastic ring comes off, it's near impossible to secure it back to the cap. Since the cap doesn't seal and the bottle starts to leak. I wish Hydro Flask would take the lid back for repair or offer some tool to put back the ring. It's not environmental friendly to have to buy a new cap every time the ring comes off.
