My husband bought me the hydroflask 18oz water bottle, which came with the original lid. I knew I wanted the straw to make drinking easier, so I tried a different brand which leaked (especially on planes) and the mouth piece cracked, so it made noise when I drank through it. I went though 2 of those with the same results? So decided to try this one. First impression was a good one! Well made, for the physique of the bottle much better, and even had a similar finish - definitely looked like it fit. It has a smaller profile, which I didn’t mind, but I think my husband would have trouble using the hole at eh top to carry around the bottle. There has been no leaking, no cracking and no noise!! My only complaint is that it’s a little difficult to pull up the spout without just touching the tip of it and pulling up. The small lip that is made to pull it open and push it closed is better for closing - seems to be at the wrong angle for opening.

Ordered a 5L bag & an 8L bag after already having a kids box and loving the materials. The images advertised for the lunch bags and description advertised both showing and describing an exterior fabric which after delivery is NOT FABRIC. The products that were delivered were more like a plastic-y exterior. This would be handy if you wanted to wipe the outside down, but also reminds me of the basic betty kids lunch boxes from Targ/WMart. I didnt pay $35+ for a Targ/WMart bag. This was by far false advertising. Reached out to C.Serv and was told the fabric outside is no longer offered and their website hasnt been updated, was offered to return. Please look at the comparison photos from Teresa H's review below. The shiny, plastic-y material is now what you will get. Disappointed in what was going to be an investment from Hydroflask.

CAUTION....I do not recommend the trail series as they are incredibly flimsy/delicate compared to the other main Hydro Flasks. The first time I used this I filled it to the brim with water and put it in my snowboarding bag and went on my way. Never dropped or banged and throughout the day when I went to take a sip of water, I gently squeezed the bottle and it dented. I am telling you I am no hulk and it blew me away how delicate this bottle was. Like a simple squeeze and it dents? I did not drop it to cause this but merely squeezed it while drinking water. I called about a warranty but I was told dents are not covered. Lesson learned to not worry about a few ounce weight and stick to the regular Hydro Flasks. This lightweight series it too delicate and almost like junk just to save a few ounces.

After destroying several plastic water bottles, I bit the bullet and bought these for my family. It has been a great investment. We have travelled all over the country and Asia with these, and they are holding up so well. The do get scratched up, but that doesn't impact the water inside. You can easily keep water cold for hours in this. In Europe last winter, I filled my water bottle up in the morning before leaving for the day, and it literally stayed cold all day long. It was so great. The inside is stainless steel, and is mold/bacteria resistant, but not proof. I have had to soak it in lemon juice and bleach a couple of times to kill what was left in the bottom after a couple of days of letting water sit in it. If you use it a lot, which I do most of the time, that does not happen. Two accessories that make so much sense to add to these, which should come as standard are the rubber boot for the bottom, and the pop up top. These make this so much more versatile, and in the case of the boot, keeps it from crashing so hard and reverberating through time and space so that everyone looks at you. I saw a lady drop one at the airport, and I swear people looked like they were about ready to hit the deck it was so loud. Overall a great investment, and one that two years into it, has paid off handsomely.
