Between my girls and me, we have six of these soft bottles. The concept is pretty nice and they pack up small. We usually bring them along in our backpacks empty and rolled up and only use them when our campsite is away from water and we need extra stored water. The attached clip is nice for hanging and the lid has yet to leak on any of us.
- Packs small
- No leaks
- Hangs easily on your backpack with the integrated clip
- Not very stable when sitting it upright
- Not sure about durability of the seams with continuous rolling of the bottle
- Bottle retains its rolled shape
We bought both the .5L and the .7L versions of these bottles to take along on backpacking trips where we were unsure of water sources. The idea is we can carry them rolled up and empty in our packs (they weigh almost nothing) and if we need extra water at the campsite, we can fill them for another 5-6L of water.
Where I've used them the most is for day hikes. Their slim design fits easily in the side pockets of my day pack where the round bottles tend to interfere with internal pack capacity. The lid seems to be pretty solid and so far, none of them have leaked. This is good because these water bottles tend to stay on their side more than standing up since the base can be pretty unstable. If you don't get the bottom properly flared out they won't stand up well.
Plus, when the water level gets lower the bottle can start rolling it's shape which throws off the balance. As you can see from the picture below, the bottle shape becomes "trained" and stays in the rolled shape once it has been stored that way for a while.
For the purpose we have these bottles, they work perfectly. We don't normally use them as an everyday water bottle like we do our Nalgenes because of the fear they'll topple over.
