Will these bottles leak if you put them inside a bag or backpack? I am worried that they will leak as they get squeezed inside.

Normally no. My kids have had about 6 Gatorade water bottles and they love them because they don't ever leak. We just got a bad one with this latest order I placed.

I never had that problem I put the bottle in last so it's not getting squashed its just sitting on top. You know what I mean?

Yes, they will leak. The membrane or seal is good, however we experienced leaks. These are great for practice and game days.

Yes, if they're on their side & they get squeezed, they'll leak (just like when you tip them up & squeeze them to squirt into your mouth).

I have not tried this but I have had containers spill inside the back pack and it did not leak out.

Nope, I haven't encountered any trouble with leakage and I've been using these water bottles for years. I throw them in my bag all the time. The black caps have rubber rings on them that block any water from seeping out.

I have never had a single problem with the lids. If anything, they are sometimes a bit too tight. Ie, a bit hard to put on at first until you practice a bit. I store hummus and salad dressing in the little ones, and have never had any leaks. I use a shopping bag, so they certainly aren't lying flat at ANY point. So thumbs up in my opinion!

They Don't leak... But you need to make sure you "snap" the lid close. if you don't hear the "snap" its not closed. :-)

Hello, no that is what is so great, I can put them in my wine fridge on their side and have not had one leak. I would recommend.

Yes, as long as you screw on the tops good, they're leak proof! I've put them in my purse sideways multiple times and nothing leaked out. They're great bottles, the perfect size. I've saved a lot of plastic bottles by buying these.

I haven't experienced leaks with them, you can place them horizontal and assuming you have a flat even surface they'll be fine, but I own these and the 5 ounce medela bottles that are fatter and I prefer those.While they haven't broken on me I feel like these are more flemsy and I can't store as much milk so I've switched to the larger ones.

The caps never go on the bottle. They just go on the bag so you can freeze your breast milk. If your worried about the bottle leaking out in your diaper bag the cap that goes over the nipple fits really well,i never had a problem with leaking.

I've used them for carrying a variety of lunches and some sloppier items, never had a problem. Never packed them tightly in a backpack where I would imagine they could pop open. I did overstuff one with rice once. It seemed the seal got loose and didn't close as tightly after that for a week or so. Now it's back to normal. I've only owned them for 6 months.

I would not trust to hold leaking liquids. The fabric did not feel waterproof or ever water resistant. That said, It will hold the bottles fine. You could wrap them in plastic bags if you are worried about leaking.

I put mine in zip lock bags, a tiny bit spilled into the zip lock bag but nothing of a concern, I might have not tighted the lip all the way

I don't pump directly into these or any bags. I pump into bottles and then pour them into these bags. I absolutely recommend these bags and use them exclusively. Never any problems with leaking.

I've been using Nalgene Cantenes for 10 years now, never had one leak. I popped one, but that was my own fault, sat on it in my pack while it was half full of water.

I put them in my kids lunches and they have not leaked. I also put them in a zip lock bag just in case - I have 1 in kindergarten, so who knows what it goes through in the classroom. Just make sure you leave about 1/2 to 1 inch in the top because liquids expand when they freeze.

I would think so, yes. However, they are very lightweight, so when it is open a liquid could easily get bumped and spilled. Also, since it is a liquid, I would suggest putting whatever you store in a Ziploc as a backup. I don't expect it would leak (it seems like a good seal), but I do this anytime when I travel with shampoos, lotions, etc., just in case.

I have not had any problems with them yet. I even put coconut oil in one of them with a lid and keep it in my swim bag. It has not leaked yet.
