Fits where other bladders don't

Does a much better job of fitting into a bicycle frame bag than other 2-3L bladders which have all sorts of extra plastic handles or huge lids or straps or etc. If all you're trying to do is carry a lot of water, then grab one of these. If you're trying to drink from it while riding, then grab the lid adapter and attach a tube to it and you're A+++ ready to ultra race.

Hydrapak is made for van life

I have the stash bottles and use them everyday and I decided to buy the 4L seeker bottle. I currently live in a van and always am worried about running out of water on the go. Being able to put that in my pocket and then fill it when I go out on a walk or to a happy hour or getting groceries is so nice. It’s just big enough to carry back/fill anywhere.

Love it, exactly what I wanted

Good strong material. Perfect size for collecting water with an opening large enough to easily fill.

Very happy. Lightweight, great seal on the lid/cap, and very durable overall. Would buy again!

Excellent products and customer service!

I had the older blue model of the Seeker 4L and it ended up with a tiny hole in it near the collar. It was still useable with the size of the hole, so I reached out to HydraPak for options on how to patch the hole and they offered to replace mine no questions asked. I sent them a few pics and they had a new one in the mail within a few days. I use this for car camping with the shower spigot attachment and it works great for washing up, refilling water bottles, etc. Solid products and excellent customer service!

Great flexibility and mobility

My second seeker. I bought these for all the work travel I do and thenhope to cut down on plastic water bottles. I usually refill at the hotel gym water cooler or airport fountains. Works great. Planning on using this second one to replace my CamelBak for a 1200 mile bike ride this summer.

Not leakproof

I purchased a Seeker 4L and 2L for a desert water carry after being impressed by product videos showing how resilient these bags are. After receiving the bags, I filled them up while doing a full prep-pack for my trip. The materials felt high quality and the bags were sturdy. Everything seemed okay until I noticed that the side of my backpack was wet. At first, I figured it was excess water in the cap threads that had leaked out, but there was too much water. I checked my internal reservoir to make sure it hadn’t been punctured, but it was fine. Finally, I held the 2 Seeker bags upside down over a sink and sure enough they started dripping, slowly but enough to be a problem. I threaded and re-threaded the caps over and over again, but couldn’t make the drips stop. I thought I had it figured out and left them on their sides on paper towel overnight to see, but the next morning the counter was soaked. I still used the bags on the trip because I had to take something, but was constantly stopping to check that they were upright and not soaking through my pack. I’m open to this being an issue of user error, but it also shouldn’t take this much time/effort to put a lid on a container. Tl;dr The leakproof caps leak.
