LifeStraw Peak Series - Collapsible Squeeze Bottle Water Filter System – 1L for Trail Running, Through Hiking, Travel, Cycling, and Fishing, Mountain Blue

Good product for condensing down Val for money I’m not too sure as this is pretty damn expensive for weight size and taste. This is all okay easy carry probably good for an emergency use

Kept in our daysack when walked Ng in the Lakes and Snowdonia. Always good to know you can have drinking water whenever you need. Also used in the Himalayas where the water cannot be relied on. Worth the money.

Really good piece of kit for when it's hot and you know that there will be a source of fresh water on your hike. I tend to use it to squeeze water into other drinks bottles, where you can add water purifying tablets (if necessary) or hydration tablets.Never used it as a straw, which I guess is only useful when water is very scarce and the design does mean it's hard to get every last bit of water out of the bag. But if you've found a good source of water this isn't really an issue.Comes with a syringe for back flushing. What would be a nice addition though is if it came with a small bottle just big enough to contain the filter in solution for long term storage or for carrying a spare.

The LifeStraw delivers exactly what it promises: safe, clean drinking water from sources you wouldn’t normally trust. The initial flow rate was excellent, though it slowed noticeably after just a few uses. Thankfully, the included syringe makes backflushing simple and quickly restores performance when the filter clogs. Still, I would’ve given this 5 stars if it didn’t need backflushing so soon.On my recent trip through the most remote mountain pass in the UK, the Lairig Ghru, it proved invaluable. I could fill the pouch, attach the filter, and drink straight away, while also topping up bottles for my friends and me with safe water.At higher altitudes, the streams are likely safe to drink untreated, but down in the glens and valleys, that’s not the case. Having the LifeStraw gave us confidence and kept us properly hydrated throughout the journey.During the Scottish Cairn Toul–Braeriach traverse, we relied on it heavily at the Wells of Dee, where stagnant water from weeks of sunshine and little rainfall looked and smelled unpleasant. Definitely not something you’d want to drink untreated. With the filter, however, we could refill, rehydrate, and keep pushing forward to complete the hike strong.And since I’m still alive, kicking, and not glued to a toilet a couple weeks later, I’d say the filter does exactly what it promises.Thanks for surviving my long review — now go survive the wild, and don’t forget to stay safe and hydrated out there!

Got this as a present for a well experienced enthusiast of hiking, orienteering and cycling. Was really appreciated and can be a life saver.

I've become ever more reliant on this when out on bigger days in the mountains, especially warm days. I can drink as needed without fear of running out of water during the day, or becoming dehydrated. Carry it empty and use it as needed to refill my water bottle as I walk.

Have been using on a trip in India, has provided a small collapsible bag that can hold a litre of water, providing a clean source of water

Broke very quickly
