Hydrapak Seeker - Collapsible Water Storage (4L/140oz) - BPA & PVC Free Camping Hydration Reservoir Bag- Mammoth Grey

I needed a big water carrier for a arid camping trip with friends, and this one reminded me of the one my friend has, which I love.This one arrived and it was everything I was hoping for! Just the right amount of “squishy stretch” to the material, seams sealed tight (I filled it all the way up and tested it overnight before putting it in my backpack), and had great attachment points. I really liked the cap “keeper” too, and the large mouth on the storage bottle. Imagine my surprise in the truck when she wondered how her water bottle escaped her backpack when she saw my new bottle. I had inadvertently and fortuitously purchased the same exact brand as hers (hers is the older 3L). Anyway, I’m exhausted and back from desert camping - this bottle performed flawlessly, just like my friends older and smaller version continues to do.Buy this brand, you won’t regret it. I’m so happy with mine, and she is with hers. She uses hers for filtration with her Katydyn filter and it’s a superb combo.

Visited an area that doesn't allow paper or plastics..no single use anythingThis worked so well I bought anotherI use it daily...no need to buy water bottles..easy to clean.....no leaksI recommend

It truly is freeze-proof. I've frozen water many times where the material gets folded in the freezer. Hasn't shown any creases or other signs of wear.The handles are solid. The cap seals even when not completely screwed on. It's weird to drink directly from but not difficult with the handles. Love it.

I bought the 4l and I loved it so much, I had to have a 2l. These things are sturdy. They collapse to fit inside the provided case and are light for camping trips. I use the 2l to carry with me when I’m walking my dog. I carabiner the pouch to my Fanny pack with the 2 sections on either side of the handle, it has essentially 3 sections to clip to. When it’s empty, it fits in to my Fanny pack with ease. The cap strap ensures you don’t lose the cap and the 360 rotation of the strap on the lid makes it easy to use. My favorite thing about these water bottles is that I can freeze them and use them as ice packs in my paddleboard cooler that later defrost and I use the water for drinking water, it saves a ton on weight. They’re extremely durable and I expect them to last many years. I haven’t bought the water filter that screws on to the top since I haven’t needed it but I’ll be sure to get that too when I need it. I highly recommend.
