Why We Like the 40oz Wide Mouth Water Bottle with Flex Cap 2.0

For an ice cold sip of water on the ready all day long, we fill up Hydro Flask's 40oz Wide Mouth Water Bottle with Flex Cap 2.0. Our thirst quencher stays pure thanks to the zero-flavor transfer property of pro-grade stainless steel, so when we reach the lookout, we can revive our soul with the refreshing straight-from-the-mountain taste of unadulterated H2O. The double-wall vacuum locks in beverage temps, whether we want that crisp sip on a summer hike or a steaming flow of coffee on cold morning commutes.

Not worth buying

[This review was collected as part of a promotion.] The cap leaks, so water spills all over the inside of my bag even though the cap is screwed on tightly. And the exterior scuffed insanely easily - just pulling it in and out of my zippered bag and there were scuffs that won’t come out! Leaking and easily scuffed. So disappointed.

New Hydro Flask

[This review was collected as part of a promotion.] I love my new Hydro Flask! I would have submitted a “Great” review if it weren’t for all the mistakes that occurred before I finally received a working Hydro Flask, but my working new one makes up for it!

Love my hydroflask

[This review was collected as part of a promotion.] Durable, perfect size for work outs, wide mouth helps with faster ice fill ups. Keeps drinks at the temp you want for long periods

Happy With My Warranty Replacement

[This review was collected as part of a promotion.] This was a warranty replacement for the 40oz wide mouth bottle that I had been using since 2016 and it works great!

Replacement bottle

[This review was collected as part of a promotion.] My bottle had the insulation compromised. I applied for the refund on the hydro flask website. After I got the information I was informed to return the bottle to the address provided. I returned the bottle along with the top. I assumed that the top was supposed to go back, since I purchased the bottle with the top. I had a wide mouth straw top. When I got my new bottle it just had the twist on top. Now I'm forced to buy another straw top. I appreciate the lifetime guarantee. But they should tell you not to return the top along with the bottle when you apply for a replacement.
