Hydrate

    Zip lock design works well. Easy to clean. Easier to use than bottles while on the move.

    I Don't Understand The Good Reviews

    • Familiarity: I've used it once or twice and have initial impressions

    This bladder is a joke - I have never been so disappointed in a product before. Yes, it is easy to fill but that is about it. My main issue is the bite valve which turned out to be a struggle for me to get water flowing through the hose no matter how I bit down. My boyfriend tried it too and he was unsuccessful as well. Then, as I was hiking, water started to leak all over me - I couldn't get water out of the hose and now it's flowing freely? I closed the valve (a feature that works if you are not using the bladder) but to be honest, as I am hiking up a mountain and I am using poles, I don't want to be constantly shutting the valve on and off when I need a drink. I got so frustrated, that I ripped the valve off and used straight from the hose every time I needed water. Plus, I had read online that you can blow air into the bladder for it to sit upright and air out - not true at all. Unless I wasn't executing the process correctly, the bladder would not stay inflated or upright.
    I am going back to my Camelbak that I should have never left in the first place - where the bite valve works and you can hang upside down to dry.

    Good Water Bladder

    • Familiarity: I've used it several times

    Overall, I think this is a great product. However, the first one I order had a faulty seal, which I discovered at home, thankfully. Had an easy return and replacement. I have since purchased two others that have been solid performers, no leaks. Just make sure to test it at home before using... but I would say that about any critical piece of gear.

    A refreshing change.

    • Familiarity: I've used it several times

    I lost the lid to my Camelbak, and it has seen a lot, so I was going to simply replace it. Then I figured why not try something new? I know that lid will show up eventually, and then I'll just have two Camelbaks, and that's silly. Nothing wrong with my Camelbak, it's never let me down, but the Platypus is a nice change. Why? It's easier to fill, it tastes less like plastic, and I like that the mouthpiece refuses to leak even if you forget to lock it. Plus you can detach the hose, and I like the clear look to this bladder as opposed to the blue alternative. I'm happy!

    My favorite

    • Familiarity: I've put it through the wringer

    Probably the best designed hydration bladder I've come across. Much prefer the zip-lock style opening to the circular ones. My friends always have a tough time filling their circular opening bladders, but there's never a problem with the Platypus.

    Simply the Best

    • Familiarity: I've put it through the wringer

    Easy to clean and fill. This doesn't have the plastic taste that I constantly had with my camelbak. Highly recommend

    Hiking Companion

    • Familiarity: I've used it several times

    I love water bladders because I hydrate significantly better than if I have to stop and open a water bottle to drink. I had a Platypus that has been through the wringer, multiple years of constant use, over multiple continents. The baffling on this one threw me off a bit, but it still has the easy clean, detach hose, and fill features I love. I'm looking forward to using this bladder for many, many trips to come!

    Easy to drink from, refill, and clean

    • Familiarity: I've put it through the wringer

    Fantastic product. Accompanies me on most outdoor adventures, unless the temp is well below freezing and I know the hose will freeze. Works well for day hikes, and longer adventures. It is easy to fill from a sink or backpacking filter, and can be hung up to make a great option for communal use in camp. It fits great in most bladder sleeves in most packs, and is a breeze to dry out and clean.
    Get the 3L- you can always fill it less or roll it up if you don't need that much fluid that day.
    I have found it useful to use a coat hanger to prop the bag open to help it dry out- just make sure to watch the sharp ends.

    Great bladder!

    • Familiarity: I've put it through the wringer

    Much easier to clean than the camelback bladders, and very durable!

    Easy to Seal

    • Familiarity: I've put it through the wringer

    The seal on this hydration bladder is great. It's easy to fill, slips into my pack nicely, and doesn't leak because of the shut-off valve.

    CamelBak to Platypus, good decision

    • Familiarity: I've used it several times

    Finally made the choice to switch to Platypus, definitely a good decision. The CamelBak I've had for a long time got a hole in it and it seems a lot less sturdy than the Platypus. The new one I just got feels sturdy and awesome. Used it a few times MTB and hiking. The mouth piece is a little harder to get water out of than the CamelBak however it doesn't leak like the CamelBak that I had.

    Easy to refill to keep hydrated

    • Familiarity: I've put it through the wringer

    I reckon we all drink more water with a bladder than a water bottle--the straw is right there when you have a spare moment while hiking or riding. I am a HUGE fan of the Platypus Big Zip! The over-sized zipper closure makes it super easy to refill as you go, so you can stay hydrated while on the trail. The straw is easy to pop on and off, so you can keep the hose in place when you refill the bladder. Overall, this is an awesome and durable bladder I'd recommend to anyone!

    Awesome Bladder

    • Familiarity: I've put it through the wringer

    Durable and convenient, water bladders are the best way to stay hydrated on the trail. This one is very simple to use, has never leaked on my gear, and is still holding strong after a long spring and summer of putting it to the test here in the deserts and mountains of UT.

    hands free hydration

    • Familiarity: I've used it several times

    Great bladder, no hassle to fill or use. So much easier than having to take your pack off to find your water bottle to get a drink.

    Great bladder

    • Familiarity: I've put it through the wringer

    I love the style of this bladder and how easy it is to open/close. It also doesn't leak.

    Haven't found anything I dislike yet

    • Familiarity: I've put it through the wringer

    Basically the title. I love the opening and clasp. Easy to fill up especially compared to watching my buddy fill his camel. No problems with leaks yet.

    Simple

    • Familiarity: I've put it through the wringer

    I purchased this hydration bag to install into my kid-carrier hiking pack. Easy to fill and clean!

    Awesome hydration bag

      The platypus 3L fits perfectly into most hydration compatible packs. I use this in my osprey 20L day pack for climbing and does the trick perfect! It is very simple and easy to use and clean! Five stars

      better than most

      • Familiarity: I've put it through the wringer

      I wanted a hydration bladder with a wide opening for cleaning and ice, and had heard these had no taste. The opening is good but I had hoped to be able to turn it inside out for cleaning and the baffle prevents that. The bite valve is not the best. You have to turn it to open it, and that's hard to do on a mountain bike. It leaks if you don't close it. Also the water does not stay all the way to the valve. But the water tastes great!
