Excellent design!

    This bag works perfectly especially for two campers. It was nice not having to make so many trips to the creek for water!

    Works great until you loose the cap.

    • Familiarity: I've put it through the wringer

    I purchased two of these. While filling up with water in a river, I dropped one of the caps and it floated away. I think this would be perfect if the cap was attached somehow. The other one was great and lasted a full 30 days with no problem bike touring through Costa Rica.

    Tried and tested

    • Familiarity: I've put it through the wringer

    I used this as water storage on a cross country journey and it exceeded all my expectations. It is very pack able and light when it needs to be taken to less accessible places, but can store plenty of water for when you get back to the car after those easy day hikes. The outer shell is sturdy and durable after rolling in my car for 3 straight months. Great product.


    • Familiarity: I've put it through the wringer

    when I went a dualsport ride I needed a small but pack able water container and this worked awesome it was easy to tie down and was tuff

    Packs up small, no leaks

    • Familiarity: I've used it several times

    I bought the 6 L blue bag; it works great. Used it over the summer 3 or 4 times and it worked flawlessly each time, no leaks. The strap comes in handy for tying to a tree. Folds up small when empty.

    Can you cross compare this guy to the MSR...

    Can you cross compare this guy to the MSR Dromedary bag of similar size?

    Cool little container

    • Familiarity: I've used it several times

    This is pretty slick.

    Soft and conforming you can put it pretty much anywhere.

    i've squeezed the heck out of it to see how tight the valve is with no leaks at all.

    super easy to operate.

    i wish it came with a hang strap or caribiner for hanging it- gotta make your own.

    not sure about cleaning it yet...fill with hot soapy water and swish i guess...

    Update: you can use soapy water or denture cleaners on this, but I couldn't really ever get it to dry. worries about mildew. might be worth just freezing it in between uses.

    Go to bladder.

    • Familiarity: I've used it several times

    This thing works great. Multiple lash points for attaching to virtually anything' trees, backpacks, whatever. One hand use. Packs up small. More versatile than any other large water bladders that I have used.

    worked great

      It worked great around camp but I am skeptical of the tap holding up. Its not threaded and you have to pull it off every time that it needs to be filled. Not sure that the seal will hold up over time.

      Yes, use caution. I discovered that the tap on mine was lost, and I have not yet been able to replace it.


        Used it on a Scout backpacking trip.. worked great! 2.5 gal was just the right size for the boys to carry from a water source to refill drinking bottles at camp and it stores really well in my pack empty.
