Flip and Sip Lid for Wide Mouth Water Bottles (including Hydroflask) made from BPA Free PlasticsFree Plastics

As a long time Hydroflask user I have no idea why the company stopped making the type of lid. It's the only one I will use and perfect for when I travel. It's silly that I have to buy this lid from a third party, and it ain't cheap, but for me, it's a necessity! This is well made and doesn't leak. Thank you!

Delivered quickly and works as described. It replaced the stock top that came with my Hydro Flask. I prefer the flip and sip instead of the twist top. Plus, the twist top won't go on if you fill the Hydro Flask with ice because of a piece of the top that protrudes into container. Not a big issue, but I have to put as much ice as I can to last during the day since I am outside away from home.

My old roommate lost me original lid to my Hydroflask so I went searching for a replacement. This one works great. Perfect fit, no leaks. I'd say all lids like this seem to be overpriced considering they're just a piece of molded plastic with a gasket, but at least this was cheaper than the Hydroflask counterpart.

It’s ok quality but it does not screw onto the Hydro Flask as far down as the original. Next time I will by the brand of the bottle

This appears to be well made and fits my eccovessel ... except for the fact that I can't use it. The tab closes so tightly that I can't get it open. A strong man managed to open it with great difficulty. I would not want to try with hot coffee inside. If I could use this lid, I would give it 5 stars. Since it is unusable, I give it the lowest rating possible.Update: Wonderful customer service. Much to my surprise, I received a credit for the price of this lid. Since there are no other complaints, I hope my experience was a one off. I would deal with this company again.Update: Not only has this company refunded my money, but they just sent me a replacement lid. I requested neither. They must monitor these reviews closely. The replacement lid works well. I am upgrading to 5 stars. I would give 10 stars to this company for customer service. I will certainly shop with them again.

I compared several brands of replacement lids for my 18 oz hydro flask coffee cup before settling on this one. It's a perfect fit. Added bonus: both the lid and the flip-up sip hole cover have a much tighter seal than the original hydro flask cap ever did. At last, I can take my coffee with me without fear of leaks. I also like that this lid isn't "branded" on the band or inside of lid with a corporate logo or name. This was an excellent purchase.

Buying it again. The existing one still has a little life in it yet. Time to order a replacement though. Nothing lasts forever. No complaints.

This top fit my 16 oz hydro flask perfectly so I thought I had a winner. Until I did a water test.While using this lid, if you get a few drops of liquid around the mouth piece and then close the lid, it can leak out the back of lid ledge (behind the hinge) if you tilt it backwards. This was the same major design flaw of the original flip tops from hydro flask. Some engineering of the of the holes and mouth piece area would fix this.One way to work around it is if you wipe the lip area every time you snap the cover back on so nothing can leak back then you have nothing to worry about. However, I am just to busy to babysit a bad design.
