3 out of 5 stars.  Good Idea, But Not Well Executed, July 30, 2010
I do a lot of hiking in Colorado. I chiefly use this Synergy Bladder for climbing 14ers.
1. Not sure I trust it. The tubes on the bottom of each of the two bladders are push on only. I am constantly worried that one or the other is going to come off.
2. The bite valve has a screw on bushing to keep the drinking tube on the bite valve. It broke on first use. I called Nathan. They are sending me a new bladder because they do not stock this 25 cent part.
3. It's tricky to fill. If you over fill the water part, you can't fit anything in the hydration drink part ... and vice versa.
4. It's very hard to clean and dry. You simply cannot remove all the liquid from either chamber to ensure the units are dry. I have tried everything. I basically leave it full of bleach water until I need it the next time.
5. The Hydration drink portion has a fold twice and Velcro closure system. It seems to seal well, but it is VERY hard to grip the tabs to open it.
6. The little cross flow valve thingy is very hard to turn. You really need to set it up before you put your pack on.
7. The little cross flow valve thingy does not feed well through the holes my pack provides for bladder tubes. It's too large.
8. Finally you really have to work to suck liquid out of this thing. Bite and suck. I find myself not getting enough liquid unless I nearly continuously work it. My first time EVER dehydrated on a hike was with this Synergy system.
9. It needs some sort of hook so you can hang it while filling and while trying to empty it and dry it out.
10. Good idea, but it might be simpler to carry two separate 1.5 liter bladders.

1 out of 5 stars.  Terrible and Ridiculous, July 15, 2010
Whose stupid idea was this?:

1) Starts to tastes strongly of plastic within two days.

2) The fluid dial is very hard to turn, so if you have problems with your finger joints or your fingers are in pain somehow you're not going to have an easy time with this unless the pain is somewhere other than the parts of your fingers where you'll be putting pressure on.

The way the thing works is also nonsensical seeming: you put water in the all water section and strangely it fills in the energy drink tube, HUH? Why aren't they separate?

3) The water section has a water cap, but the energy drink section has a stupid hard to pull apart VELCRO ROLL OPENING, and why in the world is it rolled up? I'm guessing to keep the debri the velcro will accumulate over time from easily falling into the drink section, but why the Hell is it velcro in the first place? Not as if energy packets are massive and can't be poured into a cap and not like you need to dump a canister in and can't use a spoon. Whoever gave this thing positive reviews must have done so within a few hours after having gotten this thing and pain-lovers. I should have gotten a camelback.

The positive thing, and I don't know if any other hydropacks have this, is that the bite valve section can be turned, so that it's not putting so that you can position it in a neutral position in your mouth, rather than having a tugging feeling on your teeth from an awkward angle.

5 out of 5 stars.  Awesome hydration bladder, May 16, 2010
I love my dual chamber hydration bladder. Took it out for a trail ultra today and loved it. So nice to switch between sports drink and water with such ease. Also nice and easy to clean.

4 out of 5 stars.  Finally!, April 22, 2010
I have been looking for a way to carry my accelerade and water for long trail runs and I was excited to find this. I love my Nathans vest, and the dual chamber bladder is thoughtfully designed, easy to fill and easy to clean. Two minor things: 1. the valve to change between the two bladders is hard to turn especially with cold fingers...necessitating a slowing or stopping to use two hands, (probably not a concern for men...but women who occasionally need assistance to open jars may find a similar problem) 2. I bought the bladder for use with my existing Nathans vest so perhaps the clip attachment for the shoulder strap works better with a different pack. It does not stay well on mine, and the weight of the clip helps pull the hose out of the chest strap and of course it pops out only on steep, rocky descents. The convenience and other features makes these mild annoyance well worth putting up with. Thank you Nathans for another great accompaniment to my sojourns in the woods!
