LifeStraw Peak Series - Collapsible Squeeze Bottle Water Filter System – 650ml for Trail Running, Through Hiking, Travel, Cycling, and Fishing, Dark Mountain Gray

My number one positive for the Lifestraw soft bottle is that although it does infuse a platicky taste into the water, it is much less than on any other similar bottle I have used. It is sometimes difficult to assess how effective the filter is since you do not know if you woulde have suffered had you not used it and drunk the unfiltered water. Most recently I used my Lifestraw bottle during a trip to Bolivia where tap water is generally not considered to be drinking water, with no ill effects. A minor fuss is that the filter should be wet stored, in salt water solution, when not in use. I would also like to use this bottle without the filter when I know the water is safe but the mouth piece supplied is not ideal since it is basically an open hole with nothing to stop water spilling out without the filter in place. An optional bite valve would be great.

Seems to work fine, convenient.

I did a lot of research into which water filtration soft bottle would suit me. I needed something light and durable for long days trail running or hiking in the mountains, and decided this was the right one, as reviews attested to it being light, effective and durable. I've used it on two all-day trips since it arrived, and both times it was an absolute necessity. In fact, I ended up having to share my water with others who had run out of water and had no other option. I prefer to fill it from mountain streams or lakes but apparently you can even use it with standing water. It's a great bit of kit and I'm very happy with the quality and performance so far.

Love this. Used for 3 weeks travel and despite a battering hasn’t popped

Does exactly what it's designed for Will be ordering larger one .

Poor performance. Leaves a strong taste from bottle material. Defeats purpose of filtering water

Absolutely gutted as I wanted to love this (it was amazing for 3 days - great flow, no plastic taste despite other reviews mentioning this, my water tasted fine) very lucky I had a spare filter as this could’ve been very costly. Used on a heatwave in the Italian dolomites & suddenly stopped working after a few days of use. Since I’ve got home I’ve tried using the plunger tool & following tips but still won’t allow any suction of water. Unfortunately have to return. Hate leaving bad reviews for good items but this could endanger people’s lives if stuck without water.

Impossible to get rid of the plastic flavor. Practical for traveling but every time I drink I feel revolted. I wish I could return it
