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

Seams are secure but not hard... I sewed a cover to use with mine (you can buy them too) which makes it even more comforting to use.

Not sure what you mean, but it's quite sturdy and I've never worried about them leaking

This was not soft or malleable in any way. Very sturdy, and a little stiff. Built to be durable, but not necessarily comfortable.

The sides as well as the rest of the bottle are very soft.One side is smooth and the other is ribbed,both will release the heat differently ,a plus.

My bottle, unfortunately, began to leak increasingly from a side-seam. When it got to point that it would create a pool of water around it on table, I had to replace. REI replaced, but I didn't notice that it was with a .7 liter. So now I'm buying another ... that's how much I like for now. But the seam can leak.

yes, it is a hard spout. At first the werer ok, but now it started to leak if left lying on a side or up side down.

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.

It's plastic, since I'm diluting with water I haven't seen any problems with it eroding. I haven't come across any bottles like this with glass tubes.

This bottle is quite durable. I've dropped it several times and it never breaks.

I only have the purple one, which is more of a suede material. I think it's very sturdy. The sides aren't stiff, but with containers inside, it keeps its shape. It has both a small handle and a long strap too. I've carried it into work quite a bit and haven't ever had any problems. I hope this helps!

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

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.

Not hard at all. There are side handles just below the lid handles which makes it very easy to carry. I'm very happy with this product.

NO. Its thin and brittle. I bought two. First one I thought might have been my fault (it wasn't) Second time it cracked and flooded my kitchen. It's a good idea with poor execution. I bought a 3 gallon glass bottle. Heavy but won't break unless I'm a real knucklehead!

They are leak proof & water tight. They're pretty durable but the lids are susceptible to cracking if you crank them too tight too many times. Also, I noticed after about a year when the kids (accidentally) dropped them on the ground the bottle itself cracked. I suspect this is from rugged daily use & dishwasher cleaning. I think the extreme heat from the dishwasher dries out the plastic. Even with this happening, I've been happy with the bottles. Hope this helps.

The top part used for drinking is silicone, soft and bendable. It easily folds up into the lid when you twist the top shut. The straw that enters the bottle is fairly rigid (I'd guess polypropylene), although it does bend with effort. The small size bottle fits easily into the kids' lunch box, where it's seen heavy use for this school year. They've survived so far, including the soft straw, and I suspect my little one might like to chew on his a bit.

They are fairly hard. They can be indented with my thumb just a little. I use them to carry soy sprays in my lunch bag so they are pretty durable. They do ship from China so the ship time is a couple weeks.

Hard like the photo. Can be squeezed into bar shape. Stays together well once wet.

One side of the bottle is smooth, the other side is very finely ribbed. I measured 7 ribs/cm, ~18 ribs/inch; ~1/16th" or 2mm high/deep.
