Osprey Hydraulics

The first thing that stuck out to us about the Osprey Hydraulics Reservoir is has a 1/4″/6.35mm hose which allows water to flow almost effortlessly. The exterior of this bladder has handy capacity marking also which removes any guesswork you might have to make when checking your levels. If you’re turned off by the taste of plastic (lets face it who isn’t?) this bladder may be for you. The material is a Metallocene PE with taste-free film (BPA/PVC free) plus a antimicrobial formula to which works to stop the buildup of bacteria and mold. If all this weren’t enough the low profile of this bladders’ build keeps the weight of the water consistent and close to your body. This is a particular boon for runners.

Platypus Big Zip LP – 3 Liter

Sometimes simplicity is best, and this is one thing you can certainly say about the Platypus Big Zip LP Reservoir, its simple. Its design is straightforward yet effective and its low profile makes it a great match for small running packs. Its got a slidelock opening at the top making access to the reservoir no problem at all. This system also stands up well to leaking in our experience, in that it doesn’t. The addition of silver-ion antimicrobial properties keeps things fresh and a quick-release hose and valve pairing make drinking and refilling easy. Overall this is an excellent choice for any runner.

Geigerrig Hydration Engine

Read Reviews & Buy on
If you’d like a slightly higher grade than your average Camelbak the Geigerrig Hydration Engine is one solution. Don’t be put off by the fact it looks a bit like an IV bag. This is a great concept of a bladder and works extremely well, especially if you’re running at any type of altitude. The bladder of the Hydration Engine is composed of two chambers and is built to fit into almost any pack. One key feature of this bladder we really loved is the slide top which allows for the entire top of the bladder to be open. No more fussing with a port or gasket. The slide top allows for easy refilling, cleaning and most problematic of all drying. The bite valve also works exceptionally well letting you get a healthy supply of water (without sucking too hard) but not inundating you either. It may set you back a bit more than some other options price-wise but what you get in return is unparalleled performance and durability.

Hydration is one of those things you really have to stay on top of, it can sneak up on you. You may be sitting there thinking, yeah, yeah — I know this, I’m fine, it doesn’t apply to me. If that’s actually true then great! But for the rest of us a refresher never hurts. According to one source:

Women need 2,700 milliliters daily, which is a little more than 90 ounces. Men need even more — 3,700 milliliters per day, or 125 ounces, according to the Food and Nutrition Board of the Institute of Medicine.

Thats a lot of water. How to make sure your intake levels stay up in the recommended zone? There are many ways, but one simple one is to get a good bladder and make sure it’s always tucked in your pack. This is particularly important for trail runners or ultra-marathoners. So, you need a bladder, but which one? Like so many products today the number of options has proliferated dramatically making choices more complicated. If you have a bladder you like by all means stick with it, but for those thinking about purchasing their first bladder or needing to replace an old one we’ve done some legwork for you.


A bit More About Bladders: Tips and Cleaning


How do I clean my hydration bladder?

It is very important that you practice good hygiene, cleaning your reservoir consistently, and caring for it properly after use. Cleaning instructions are as follows:

  • Start with hot (almost boiling) water and 2 tablespoons of baking soda or bleach.  Mix the solution thoroughly inside and hold it up above your head while you apply pressure to the bite valve, making sure the solution runs through the tub as well.
  • Let the reservoir and cleaning mixture soak for roughly 30 minutes
  • Rinse  the reservoir with hot water and non-chemical soap. Be certain you’ve cleaned all the bleach before resuming use. You can also take a toothbrush (or other small brush) and gently scrub the interior of the reservoir
  • Once the reservoir is clean, make sure you air dry so that no moisture ends up trapped inside the bladder. Sometimes stuffing clean rags inside can help to this end.


How often should I clean it?

This is a bit down to personal preference (and how much you use it). A few times a year is likely good or even less if you care for it well after use.


Can I drink other liquids from it besides water?

Of course you can, but in our experience strongly flavored drinks will have a lingering effect. If you must drink alcohol from it we highly recommend you get a separate bladder for this. Hints of tequila don’t go down particularly well during a 5k.


How should I store my bladder when it’s not in use?

Make sure that it is completely dry, roll it up and stow it in the freezer. This will ensure nothing can grow in it. If you’ve got limited freezer space anywhere dry will do.
