Does this bottle have malleable side seams or are they rock hard?

The side seams are strong but malleable. When the bottle is filled with water they expand and you can't feel them, if that's what you mean. The bottle is comfortable when filled, except for the funnel part, but that can't be helped. ;)

Its all pretty malleable. The only stiffer part is the neck where the stopper is screwed in.

It is a hard plastic. It will withstand chewing if that is a concern. Inside there is a silicon liner making it spill proof but also hard to suck at first. After it gets broken in its the best kids water bottle out there.

I have occasionally noticed a little "sweating", but never an issue with handling the bottle. Might be different in a more humid climate.

No this is not normal, my bottle has a very hard snap when closing it's never spilled.

A hard plastic. And though the bottle will not break, the lid will, if dropped on a hardwood floor. That happened to me. But overall, I like the bottle. I bought a second one and I just switch the unbroken top to the other bottle while cleaning the other.

It feels more aluminium. I use it for the gym, it is strong.Just make sure you dry the inside as mine has started to form black specs from lack of drying. my fault not the bottles.its a very good product.

The stopper plastic part that enter into the bottle is solid. The crystal part of the stopper seems to be hollow but looks thick. Hope this will help.

Each side of the bottle is different. One side has a nearly flat diamond pattern, it allows the most heat to transfer. The height of the pattern is insignificant since it transfers heat as well as a totally smooth surface - but it is not smooth as a babies bottom, you can feel the tiny bit of texture. The other side is more deeply textured, with very narrow and soft ribs. This side transfers less heat, for times when the hot water inside is just too hot to be right next to a person. So to answer your questions, it is not perfectly smooth. Whether the diamond side would suit your needs is up to you. Hope this helps. Each side of the bottle is different.

They are not hard like an acrylic, but not super squishy, an older kid can squish if he really wanted to but there is no point cause the opening you drink out of is big enough to to pour. They have never popped open on me, but I wouldn't put it in a gym bag or back back that gets bashed around. I have a bunch we use for refilling for cold water, that is all I put iin them.

Yes it's a hard plastic but not as hard as a nalgene bottle. It has a little give if you squeeze hard enough.

The bottle does seem to be more durable especially with the paint on them but will still dent if dropped on a hard surface. I had a Klean Kanteen and wasn't a huge fan due to the denting but I love the Hydro Flask. I own an 18 and 32 oz but use the 32 oz far more. I have a few Nalgene too but hardly use them any more since getting the 32 oz because the Hydro Flask doesn't sweat and keeps liquids cold or hot for hours.

I haven't been too rough with mine, but the thing is pretty tough. However, the plastic zippers on the side pockets almost immediately tear off. The main pocket has metal zippers, and those are tough as nails. I've had mine for a bit over a year now, and besides the zippers on the sides coming off within about 2 weeks of purchasing it, it's still as if it's brand new. As long as you don't mind using the side zippers from the metal base that lays on the tracks, this thing probably won't fall apart on you. As far as space goes, I've fit 4 pairs of shorts, 4 shirts, a towel, a blender bottle, a pair of shoes and some miscellaneous hygiene products with a little room to spare.

it's hard plastic. Not like soda bottle hard, it still gives a little if you push into it.

I never heard of Nalgene Bottles, but what I have is a hard plastic, very sturdy. Love the ring so I can carry it around while I workout, plus the no leak lid is great.

Mine was smooth but when I took the lid off it cracked and chunks of hard plastic went everywhere. I just bagged it to keep it from getting dry. I make creams and as I used my last batch it got clumpy and crumbly but performed just as well.

This bottle is a soft flexible plastic. It has been left in heat and dropped and still looks brand new worth no damage

Yes. The bottle is flimsy. Once you put either hot liquid in it or it get hot in the sun it deforms.
