Since this is soft bottle, will it leak if it is put in snug pocket of backpack (which would "squeeze" bottle)?

No, it's quite hard. Mine only leaked from screwing on the top too tight and cracking the plastic.

I have similar experience, I think cause it a soft bag and one or two ounce liquid is a little light. Maybe we should trust more on bottle when small-sizes.

The pockets on the side are not large enough to hold a water bottle, unless it's tiny. The pockets are about 3" deep flat (with 3-d object depth ~2.5") and if you're really stuffing, you can fit something with a diameter of ~2.5". You would be able to fit the bottle inside the bag since the width of the bag is typically beyond the width of anything I carry(laptop-long ways, textbook size books, or a 3 ring binder), leaving room on the side for a water bottle

mine fits snug in the neck of the bottle, no problems with it falling into the bottle. I would definitely recommend this product.

Assuming you have the cap on and tightened appropriately, it will hold the water just fine. However if it's upside down and in a bag, there's a decent chance that something will push on the cap's clip/lever with just enough force to open it. Remember, they're meant to open with the force of your thumb, so that's all it needs for something to dump the liquid inside.

YES The bottle is just sitting in the groove of where the zipper is. My 7th grader uses this as her lunch bag and it has held up well. They do not have locker so she has to carry it all day in her backpack. No leaking or sweating from the tote at all.

It should not, if you close the top with a click and don't jostle it too much. Be careful though, it will leak if it is full and jostled. I put my bottle in a plastic bag before putting it in my backpack. Good luck, the blender makes making smoothies very easy and easy to clean up.

Not really. You could technically put one in the pocket with the water bottle but sometimes it leaks or sweats slightly so you'd risk getting your phone wet

I haven't tried it but I suspect that the water would be forced out of the bladder. The laptop compartment is next to your back so the entire weight of the backpack would be on it. I would also be concerned about having the bladder next to the electronics in case of leaks. Water and electronics are not friends....

I have only used a cold pack with this cooler, so I'm not sure how ice would fare. I think if the ice were placed in a resealable baggie, then placed in the backpack, it would not leak.

It has a slight squeeze to the bottle for easy dispensing. But be careful not to lay it on its side. It will leak. It applies easily and smooth.

The gel is a bit liquid-like, so it may leak out of a bag, but if you put it in small plastic Tupperware/Rubbermaid packages and put pinholes in the top, it would work and not spill out.

Yes it does (actually have it in hand and make it leak). For my use it's not an issue since I dont put it in any bag (unless restrained). So it remains always in a normal position. It's handy way to open with a single hand and protected from dust bottleneck is precious on a bike ride especially on dusty busy roads.I remember my old (lost), one hardly leaked. I don't know what happen to the quality. But the design remained unchaged since the 199x patent (I have a copy). Although a little modification would improve, even make it unleakable. I have a Thermos Tritan (same name yes, check with Google) not as easy to open, that doesn't leak at all. Yes it does (actually have it in hand and make it leak).

No. I would recommend putting the bottle in a sealed ziplock and laying it horizontally in a travel bag. Make sure there are no items on the side of the bottle that could push the pump down. If it does happen, at least the bottle is in a bag to prevent leakage.

My experience is no leaking from this bottle as long as the cap is on tight and the flip lid is closed. Great product!

This is absolute leak proof. At least so far I never had 1 drop coming out of it!! Im sure you can take it in a backpack.

I don't have bottles that large...mine are 20 oz. and it holds them fine. I will say that this pack, although light-weight, has trouble with the weight of the bottles on the sides unless packed full in the large pocket. It collapses easily if not filled. So it works if you have a couple jackets or other bulky items in the large pocket.
