Great new lid for my hydro flask. (I previously used the chug cap, but it developed a crack and began to leak. I think I over-tightened the lid and messed up the threading). This new lid is much more convenient and easier to use. It can leak a tiny bit if the bottle is really full and turns sideways, but it's never really an issue for me.

I am so happy I bought it! Works great, easy to use and wash and no leaks. Fits perfectly. Great quality, smart design and not expensive. Highly recommended especially if you love your flask and not satisfied with its old lid.

I’m impressed with the Hydro Flask Wide Mouth Lid! I found a Hydro Flask at a thrift store for just $5, and this lid fit perfectly. It’s sturdy, easy to use, and made the bottle fully functional again. Great value and quality!

In this modest yet valiant Hydro Flask Wide Mouth Lid, I beheld a guardian fashioned for the wanderer who roams through storm and sun with a trusted vessel in hand. Though small in stature, it possesses the steadfast spirit of a clasped promise: to keep the waters within pure and still, untouched by the world’s rough jostling. Crafted to crown the wide-mouthed bottle like a helm upon a loyal knight, it seals with a surety that brooks no doubt, holding warmth against winter’s bite and coolness against summer’s relentless blaze. Its hinge and handle, simple though they appear, speak of journeys long and solitary—of travelers pressing across wind-scoured hills or pacing dim forest paths where only the whisper of leaves offers companionship. The lid lifts and closes with the measured grace of a vow well kept, neither stiff nor fickle, but obedient to the user’s need. In truth, there is a peculiar solace in such a piece—an accessory often overlooked, yet vital in its constancy. It grants the bottle a renewed purpose, ensuring that no drop of refreshment escapes before its rightful moment. Thus does this small guardian become a quiet companion to thirst and thought alike, ever ready to brave the shifting world while preserving the comfort contained within.

Very handy and durable. The only comment I have is that it may splash water when closing at times. Apart from that its great quality and a good replacer for the original fit

Works fine but I think Hydroflask is overdue for a cleaner straw lid concept. Tends to leak if not closed properly and not too huge of a fan of the exposed straw part. This also used to be $10 when it first released and now it’s $15? Not sure why the markup, but does the job.

I am daily driving this Hydroflask lid. I think this is the 6th lid that I have used on my Hydroflask. Great quality as always. Holds up well to heavy use and occasional drops. I have broken ever model of lid (40 oz bottle is heavy when full). The seal can get a bit tighter than I would prefer at times. The strap is adequate for the weight and I keep an airtag clipped to it at all times.

It fit perfectly on my 40 oz hydroflask water bottle and my boyfriend’s 64 oz hydroflask as well. It also came with 2 straws. I accidentally bought extra straws then I when it came in I realized it came with 2. The handle is easy to hold and there won’t be any water spilled from the lid seal or the straw part. 10/10! The lid made it much easier to drink water.
