Seeker - Collapsible Camping Water Storage (2L) - BPA & PVC Free, Hydration Reservoir Bag, Leak Proof - Mammoth Grey

I purchased the 2L version and have found so many uses for it. I take it camping, I take it hiking (when I need to carry water for more than just me), and I found it is perfect for college football games where outside food and drink are prohibited. Cons 1. The only con I have really found has little to do with this product. It is not insulated, so don't expect it to keep water hot or cold. 2. Oh I almost forgot, it is somewhat hard to clean the inside. So I would only use it for water and then find a way to prop it upside down and open so it can dry out. Pros 1. Collapses really small (like smaller than my fist). 2. The mouth is big enough that it is easy to fill yet small enough it is easy to drink from. 3. Does not spill, even when squeezed 4. Seems pretty tough and hard to puncture, not that I have taken a knife to it, but have definitely dropped it on rocks and the road.

I have used this for backpacking and it works quite well. You can carry it empty and collapsed down until you find a water source, avoiding the need to carry empty bottles that still take up space. Then as you use it, it takes up less space and weight of course. I definitely feel this is a well-made product and recommend for those who might require extra water storage at times during backpacking trips.

I run an outdoor summer camp, leading groups of older kids on backcountry day trips, and this 4L water bladder has become an essential part of our gear. My staff and I use them to top off water bottles throughout the day. I originally bought these with the assumption that they’d be a temporary solution until they wore out. Four summers later, they’re still going strong. These bladders are in constant use: filled daily, packed and repacked, shoved in and out of backpacks, rolled for storage in the off-season. Despite the heavy wear and tear, they haven’t leaked, spilled, or failed in any way. Their reliability has exceeded my expectations. The only reason I’m purchasing another is because I lost one, not because it broke. At this price, you simply won’t find a better combination of durability, functionality, and value. Highly recommended.

I’m a big fan of these things, I own three sizes. The big plus is their flexibility. I use them almost exclusively in sea kayaks and they fit and flex to the hull and tend to stay put. Truth be told I use this larger one more often as a weight distribution device for the boat rather than water storage. But of course it’s good at that too. The handles are very handy for this one. And FYI I’ve not had any of mine leak, they are quite durable. Also very useful that they collapse down when not filled. These are always with me on my trips.

So I got this to be an actual water bottle I intended to use for hiking. It is not great for hiking. PROs - extremely light, great to pour into a drinking or cooking container. Once it was rinsed and aired out there was no “off gassing” type smells or tastes. Easy to measure water content. Felt very damage-resistant despite being very very light! CONs - you can’t gracefully or easily drink from the opening. It’s really meant for pouring. It is very challenging to hold / carry for long hikes because the lid loop bends a bunch when it’s hooked into anything. The handle is ok but also not great for long hikes. Because it’s so light supporting it upside down (for pouring or drinking) is like handling a live fish. It’s squirmy! Bottom line - really great quality and utility - not great for drinking from on long hikes.

amazing product! love it

Me and my fiance loved using this to carry a little extra water during our backpacking trip. I especially enjoyed that I can pour water from it like a pitcher. This made it easy to put clean water into our cooking pot. Durable. Good value.

I use this in conjunction with a Sawyer water filter. Perfect combo for bike packing.

Tijdens mijn fietsreizen zijn twee drinkbussen van elk 750ml niet voldoende, vooral als het heel warm is of als ik wil/moet wildkamperen. Nu vul ik de Hydrapak, die ik op mijn bagage achteraan vastmaak, en zo heb ik 2 liter extra water! Meer dan genoeg om te drinken, 's avonds eten te maken en af te wassen, en dan nog voldoende water te hebben om de volgende dag te vertrekken tot ik onderweg terug kan bijvullen! Een prima aankoop! (en ook nog eens 100% lekvrij !!!) Ik heb nu ook een tweede gekocht.

登山用に購入しましたが、漏れもないし大容量だしで文句がありません。 乾かすのが手間ですが、おすすめです。

Great hydrapak that fits my Katadyn be free filter

Easily stored and big capacity if you're going to the gym or hiking

Very, Very Good Product & Very, Very Good Deal
