Super useful for water transport when backpacking in a group
Very helpful on a recent Philmont trek, for water transport for the group. Its best for refilling water bladders that have a large opening. it is less useful for refilling smartwater bottles with smaller openings.

Pros and cons
I give these 3 and my partner gives them 5 so we're settling on 4. They like that the containers are the right size and shape for fitting into the bottoms our kayak hatches. I don't like that they are difficult to pour from and easy to overlook when packing since the dark grey blends in with the beach. Also would be nice if the cap were attached, seems really easy to lose it.

Durable and Useful
Where were these things 5 years ago?????? This solves so many problems on the trail - from the need to hike in water from a long ways away, to camping near a creek, and just wanting to splurge on lots of coffee and hot cocoa. Definitely a game changer

Hardly any taste
Been using regularly for a month. It's tougher than it looks. I love the measurement on the side, it's easy to fit in a pack, since it's more flexible than, say, and MSR Bladder. Best of all, it doesn't have a horrid taste. It's not completely tasteless, but it doesn't taste like the inside of a burning tire, like all the other bladders I've tried. Overall, a very good product.

Great product if I could use it.
Huge fan of sea to summit products in general. But this is unusable. The taste and smell it imparts onto the water you are attempting to drink makes it undrinkable. Don't waste your money on this product. I wish I had used it in enough time to return it, but I went past the return date. Not sure how anyone could have given this product anything more than a one star rating.

No bad taste
Seems to be made good no leaks. I left water in it for 4 days and didn't have any bad taste. Easy to pour out of to fill something up.

Strong but weird taste
Durable bag but water gets a weird taste from the plastic even after rinsing the bag multiple times.

思ったよりも生地が薄かった。

There are two models of this product. This one only has a screw lid. Not an easy pour. If the cell is full Of water it is impossible not to spill half before pouring. Get the one with the lid that doubles as a shower/spout. Oh and you can’t buy the lids separately, so mine went in the bin unfortunately.

Absolut zu empfehlen, haben wir immer beim Wanderpaddeln und Fahrradtouren dabei, seit diesem Jahr auch im Camper haben da zwar einen Wassertank den nutze ich aber nie

Ottimo acquisto

Excellent for fitness training trail running extra weight in backpack. When weight becomes to much just empty out water and continue running. Much better than weighted vest!
