Platypus Ultralight Collapsible SoftBottle with Push-Pull Cap

I've owned maybe 10 of these bottles over the past 8 years. Some last over a year, some only a couple of months. I use them maybe 5x a week for snowboarding - it's great to put water in and it fits well in my pockets.zThe failure rates are inconsistent, and inconsistent in where they fail. Some start leaking in the middle, at the side of the bottle. This is probably due to bending during storage. Others fail underneath the bottle (at the foot), on the inside. One could call this a folded part as well, but I've seen more of the newer bottles I've purchased fail at the bottoms. The older ones never failed at the bottom, so maybe it's a quality control issue.

I'm having a tough time writing a review on this. I love these bottles and I'm sure these ones work great! I ordered two and neither came with caps. I went to replace them and only one could be replaced. I did that and the new one came with a cap. (that was bottle number 3) I bought a second one to replace the first on that could only be returned and the new one I got didn't have a cap (bottle number 4). I contacted the seller (Amazon) to see if they would just send me a cap. They said they could not do that and offered to do another replacement. Fine. I just got the replacement today (bottle number 5), and again it has no cap. As long as you don't mind buying the caps separate, then these bottles are great and very durable.

Overall: worth buying for a light weight backpacking bottle. Probably the best overall option on Amazon. I own two of these personally.Good:Lightweight (much lighter than a Nalgene)Rolls/folds up into a small space (can fit multiple bottles in one side pocket)Good priceBPA freeSport cap (easy to drink on the move, can use it to wash dishes and hands while at camp without wasting much water)Cons:Some people have noted the slippery top cap. I don't even bother with it and tossed the cap in the recycling bin. It adds an unnecessary step between me and a drink of water. It also adds unnecessary (though negligible) weight to the pack. Besides, you'll probably lose it after a few hikes anyway.The other thing that I don't like is that the bottle hard to clean and takes a long time to dry. However, this is not particular to this bottle, but a problem for soft bottles and hydration packs in general. For every day use and short day hikes, I just use a nalgene bottle. For long distances and overnight through hikes, though, these are worth the hassle of cleaning/drying once you get home. On the trail, you can just rinse and reuse with tap water, so no worries.

I purchased this item with the intention of skiing. I wanted a bottle that could easily fit in my jacket for in bounds days when I didn’t want to carry a full pack. I was between this water bottle, the same bottle but with a standard screw cap and a similar .7L bottle made by Vapur. I ended up going with the standard cap. The Vapur was good quality, but .7L was slightly large for ski jacket pockets and the cap was more sizable. The push pull cap was firm which I saw as a must to ensure it did not leak in my pocket, but it did not screw onto the bottle as much as the standard screw cap, so I went with the standard cap for security reasons. That said, I have heard of people using the push pull for skiing without problems, but I still liked the increased security of the screw cap. The only downside with the screw cap is that you have to hold the cap when it’s off so there is a possibility you could drop it.

I LOVE my Platypus bottles! I carried 2 1-Liter bottles last year during daytime hiking trips in Peru, and love that I (1) did not have to deal with bulky empty bottles when I was done and (2) was able to refill them and reuse them over and over without worrying about them rupturing or leaking. They're great quality and hold up for a lot of uses. I also prefer the push-pull cap on these to just a regular screw-off cap on some other bottles. Here's a tip; when empty, blow into the bottle to "inflate" it, and place it upside down to dry so that it fully dries out and you don't get any mildew in the nooks and crannies.

Great water bottle. But with normal use for just five weeks the crease along the center line of the bottom of the bottle has fatigued and torn. Now it leaks, this pretty much makes it useless. This seems to be a design flaw: a failure to consider fatigue in the material selection for the bottom panel of the bottle.

I really enjoyed this water bottle. I took it with me on daily runs, multiple times a week and now it has sprung a leak. While running in the park, I found my right leg wet. I thought, "it's not raining on my right leg, more is there a dog peeing on my upper thigh. Where is this water coming from?" I remove the water bottle from my pocket to find, my water bottle. It seemed fine. I gave it a small squeeze and it took a leak out of the bottom of it. Not great! So now I must retire this water bottle less than 3 months after buying.Pros: It held water when I bought it; it rolls up when empty, it's light.Cons: It don't last. Save ya moneys.

Utterly brilliant. My trick is to stay hydrated while flying, I always carry a flat, empty Platypus through customs, then fill it from the tap in the bathroom before getting on the plane. In nasty British airports like Heathrow and Gatwick just fill up even though the tap is hot and it says the water's undrinkable (it's rubbish) and by the time you're in the air and in need of a drink of water, it will have cooled down.These do tend to have a reliability problem in that they sometimes leak around the top, but if that happens, just return it for a replacement; Platypus have a great warranty....

I love this bottle. It’s surprisingly hard wearing and folds up to be tucked into a bag or pocket when it’s empty. Super for walking and travel. Really lightweight.I got this because I owned a platy hoser for my backpack which has been reliably leak-proof. This one seems to be reliable too. Dragged it around with me in Canada, kayaking and walking and it’s still in really good condition.

Perfect size for a sports drink. They improved on the old design. I already lost the cap, maybe a retainer on a plastic ring would be a good idea... or I could be more careful.

Can't go wrong with a Platypus , this one was transparent which i like, solid as a rock waterbottle

This is a brilliant product purchased to replace one bought over ten years ago and used daily. I've saved a fortune on buying bottles of water using the Platypus Softbottle which never leaks.
