Fluid Insulated Stainless Steel Water Bottle by Sports (Midnight Blue) - 40 Oz, Wide Mouth, BPA Free, Bonus Flip-top Lid Included

This is by far the best water bottle I have ever purchased. Having used the bottle for over two months, I have not had a single issue with it. It provides excellent thermal insulation for both very cold and very hot liquids. From ice water keeping ice cubes still frozen for an entire day, to keeping hot coffee piping hot for hours on hours. I primarily use the screw on cap which seals extremely well and have no had any issues with it leaking. The construction of the bottle itself is also very durable and resistant to dings and scratches from rough surfaces and dropping. I have not had a single scratch or dent in the bottle.This water bottle is an excellent value compared to it's much more expensive competitors (Hydroflask). I would highly recommend it to anyone looking for a larger sized stainless steel bottle with incredible insulation properties.

I have had Hydroflasks for years. Unfortunately, they have gotten really beaten up by years of hard usage, so I wanted a back up. I bought this one as well as a 24 oz narrower flask and both of them do not disappoint. I was afraid that neither would keep drinks as hot or cold as my Hydroflasks ( yes, I have more than one) The thermal performance of these vacuum insulated flasks is excellent in the last two weeks since I have been using them. They are as good as my previous bottles and all the accessories fit perfectly as well. Delivery was on time and the packaging is as illustrated on the Amazon site. One downside is that the flip top lids do not click shut as snuggly as the Hydroflask ones, but replacements are easily found if you like that sort of cap. The also included screw top is insulated and works perfectly. I use wide mouth lid with attached straw so this slight potential issue doesn't affect me. These are an great option to a hydroflask.

Really pleased with the way the bottle works. I've only used it to keep thing cool not hot, but it kept my water cool after being left out in the hots sun. The bottle was extremely hot to the touch, but the water wasn't and this is after I've dropped the bottle a few times. I am so happy that it came with two lids that I can change out for my convenience. One problem that I have with it is that it only comes as painted. This is a problem for me because chipped paint is more noticeable than a scratch on unpainted stainless steel and my bottles get tossed around rocks and trees and covered in mud during all of my hikes and work days.

I bought this bottle because I was looking for a large capacity vessel to take with me outdoors. The look and finish of the bottle is very nice and I like it. I have been using the standard stainless lid and I will say that it seals well and does not leak even if tilted or laying on its side. However, I was mainly interested in the insulated properties to ensure a nice cold drink of water and this bottle left me disappointed. I filled it with 80% water and topped it with ice and within less than 2 hours outside the ice had already melted. I even experimented with it at home and had similar results indoors.

I have a HydroFlask 40oz that I received as a gift about a year ago but it was purple (PURPLE!) so I only used it at my desk at home. I liked it so much I wanted a smaller one I can fit in the cup holder in my truck but they're pretty expensive for the original. I found the Fluid 24oz and got carried away and ordered this one too since both still cost less than 1 HydroFlask.I originally ordered them a week ago. When I got them, I filled both with as much ice as it could hold and then filled it with water. The 24oz stayed cold for over 24 hrs and still had small pieces of ice. The 40oz was warm after a few hours and no ice left. I also noticed the outside of the bottle was very cold, like there was no insulation. The powder coating on the bottom looked like it bubbled up in the center and there might've been a vacuum leak which would explain why it didn't stay cold. I returned it and ordered another one to give it another shot since the 24oz worked great. I got the replacement 40oz and tried the same test and it seems to work just like my HydroFlask and 24oz bottle.I'm using Tahvo straw caps (bought on Amazon) on all of them. The caps that come with the bottle have gaskets that might not be fully seated in the groove. During my testing, the first one leaked and found that seating the gasket properly stopped the leaking.I thought about giving this 4 stars but with Amazon's free return and Prime 2 day shipping, exchanging it was almost painless and I'm very happy with both bottles now.

Love the fact that my water stays cold throughout the day. However, the cap leaks and opens easily.**update, figured out why the cap leaks- its defective. It doesn't have a sealing ring and the plastic hole that supposed to allow air through is too small.

It's metal, so every drop dents it pretty easy. The lids seal gets messed up rather easily and i'm always finding water lines dripping down the sides of my bottle. Additionally, because of how the lid is made, if you put ice in it, you are inevitably going to be jerking the bottle back and forth trying to move the ice from in front of the lid so you can get a decent size sip of water. Otherwise, it's a great bottle, it provides great insulation!

I have had this bottle for almost a year now and I love it. It holds ice and hot water just as well as a Hydro Flask ( My friend who owns a HydroFlask and I have made several tests and they perform equally). I have taken this thing out camping various times and has been dragged and dropped on multiple occasions, it has a few scratches and dings here and there but still performs fine. The only problem i have had with this is that I dropped it once from about 2 ft of the ground full of water and landed on the cap and the cap broke but I contacted Fluid sports and they immediately sent me a new one, great costumer service, they responded quick. Overall I really recommend this bottle, you cant beat the price and quality of it plus the great costumer service.
