Big Zip Water Reservoir for Hydration Backpacks, 1.5-Liter, EVO with Fast Flow Valve, one color

I bought a couple of different baldders. Offbrand and name brand. They all tasted like chemicals/plastic. Disgusting. I have a Platypus water filtration set and really like it so I thought Id try this. It's fantastic. I'm not sure how people are complaining about flow rate. They probably don't have the valve open correctly. Or it's pinched. Flow rate - Fantastic Taste - Very minimal that went away after a couple of uses. Leaks - None at all Ease of filling - Very easy to fill while left in my bag. Ease of cleaning - Can't get my hand all the way down, but I can't in any other bladder either. The mouth opens wide enough that cleaning and drying is easy. Bit valve - Doesn't leak. Allows good flow. Comfortable to bite on/use. Sturdy. Overall there really isn't anything that I DONT like about it. A hose cover wouldn't have hurt my feelings, but not a big deal. I guess the one thing I don't like is the price. Plastic tube, welded plastic baldder, and a bite valve can't cost more than a few bucks to make in bulk. Almost $40 retail is a hell of a profit margin and does rub my sensibilities a bit wrong. But compared to similar options at the same price point... I'd pay it again.

It has a great flow, it's very durable. It's easy to clean and fill. I throw it in the freezer overnight a lot and haven't had any problems. No leaks. I just wish there was a backpack specifically designed for it...

I have used Camelbak hydration bladders in the past and so I was hesitant to change brands. To be honest, after trying both, I much rather prefer this pack by Platypus for these reasons: 1) Absolutely NO plastic taste on the first use, not even after the water sat in it for a few hours. Hallelujah! The Camelbak has always had an off taste to me. 2) The zipper on the top (vs the circle on the front of the Camelbak) makes filling a breeze, and refilling even more of a breeze. One simply has to open the top instead of digging into the pack to find the circle twist cap! 3) I found the bite valve bigger and easier to use. 4) Since the opening is large and on the top, I found it much easier to clean and also to dry--no lip to catch water like the Camelbak (from the circle twist opening.) 5) Once again, NO PLASTIC TASTE!!! This hydration bladder exceeded every expectation that I had. I used it for an 8 hour hike, refilled it once, and had no issues. It is well made, super easy to clean, and I cannot praise the easy to use design enough. I have a Flashpack 18 from REI and it fit perfectly inside. I highly recommend!

I like this bladder a lot. I've used a lot in the military and this one had many great features. The pull from the bottom feature where the tube is captured with a plastic piece is a nice design. The tube also connects with quick push button disconnect fir easily cleaning. There is a spacer inside middle that's great to keep separated for drying after use. The only problem, tube a little thin and short. I replaced with longer, thicker one from military gear. But the bladder is superior and perfect ballance of thickness to weight. I would buy again, actually did in diffetent size.

I put 50 Rocky Mountain miles on over a long weekend using this Platypus Biz Zip 3 liter EVO with the Fast Flow Valve. It worked perfectly! It was easy to fill, easy to drink from, fit in my pack, came with a clip that did the job of holding the mouth piece. I could not be happier. If I was going to make suggestions: The turn switch on the mouth pc., seems wrong. But that is from a plumping point of view. The turn switch is OFF when its in line with the hose and ON when its perpendicular to the hose. And the hose coming out of the 'bag' is harder to clear when cleaning. But VERY minor. Just a great smart product!

Took this guy backpacking with about 11 hours of walking. I like the big opening on top, which makes it easier to refill, pour water out, and dry! The blue thing that's used to lock the top will fall if you carry it by that, so don't do that as it's not meant for that. I also like the detachable hose, makes it easy for me to get it out of my bag if I just need the bladder. There was no plastic taste for me since I first got it. Stood up to my abuse of trying to really put/squish in my pack. The first time I did put it on my backpack though, I filled it to 3L with a full backpack and a couple of minutes later I realized that it had started to leak a lot. I took it out and saw that the bottom tube connecting to the bladder had slipped out and that was a hassle. I made sure to fully insert the tube to the adapter connecting to the bladder, and while I was weary for a couple of times after that, it never came out again! So just make sure the first time you get it that the tube is all the way in.

I looked up some product reviews on other websites before buying this hydration bladder, and it got high marks in all categories. Amazon had the second best price, along with the best return policy. I wanted it to fit into the bladder pocket of a fairly small day-pack I've got that I love and use often. Reviewers described it as the most durable bladder with the quickest water flow, and no funny taste. It was also described as a little wider than most others with the same capacity, and the easiest to clean because of the wide mouth at the top (instead of a screw-on cap, like most others). I agree with all of it. I LOVE it! But just be ready - it is a little wide. Not a problem for me - with a little effort, it fits into my pack snugly and doesn't wiggle around. But measure your pack carefully (like I did) before you buy it. ;)

I have used a wide variety of hydration packs over the last 18 years. I am not a fan of most camelback products due to how they are made now. I purchased this product alongside the "Source Outdoor Widepac Hydration System Reservoir with Helix Bite Valve, 3-Liter" and I prefer the "Platypus Big Zip Water Reservoir for Hydration Backpacks, 3-Liter, EVO with Fast Flow Valve". First, the material on this one seems much higher quality and the seams around the reservoir are THICC. I also prefer how the mouthpiece quick-connect is located at the top of the bladder. It makes for refilling and re-inserting the bladder back into my back swift and easy. In addition, I have attached the Sawyer Mini to it and it works best outside of my pack, for ease of use and everything. The mouthpiece on this bladder is better than the Helix one in my opinion because I don't have to fumble with turning it, I much prefer the lever action to enable and disable flow. Plus, I feel more comfortable with relying on it to last a while due to less moving parts than the Helix from the other bladder. 100% buy this.

Era necessari

ハイドレーションは苦手で長く使ってませんでしたが、これは使えそうだと思いました。 ・ハイドレーションはパッキングがとにかく面倒でしたが、これはジップを閉じて上部チューブを外しておけば水が漏れません。前日に水を入れてパッキングしても、移動時にザックの中が大惨事にならずに済みます。 ・上部からチューブをジョイントする構造のおかげで、出発直前のチューブの取り回しがとっても簡単です。 ・ジップ部分は取っ手をギュッとつまめばまあまあな広さに開口し、ポカリ粉末の投入も楽にできます。（けど手を突っ込んで洗えるほどじゃない） ・本体内のスペーサーのおかげで内部が乾きやすいです。 ・モンベルのバーサライトパック20Lにピッタリ収まります（モンベル純正のウォーターパックは安くていいけど、ホースを一番下から繋ぐ必要があるのと、バイト部分に開閉バルブがないので避けました）。 不便に思っていたところがかなり解消されていて、これなら使う気になれそうだと思いました。 ただし使用後の洗浄はやっぱり手間です。特にチューブを繋がないと弁が開かない構造のため、本体側に付いているチューブ部分の洗浄は面倒です。それと料理用の水筒としては自立しないしジッパー開けるのがすごく手間で使い物にならないので、テント泊の場合は普通のペラペラのプラティパスも丸めて持っていくことになります。 スピード重視の日帰り山行にはこっち、テント泊のゆっくり登山なら従来のプラティパスと使い分けることになると思います。 ちなみに、プラティパスのペラペラ水筒は10年以上使ってるものもありますが、未だに破れたり漏れたりしてません。耐久性には本当に信頼をおいています。

Jag är nöjd! Vattnet smakar inte plast som med vissa liknande. Lätt att fylla upp och rengöra.

Poche à eau d'une belle contenance. Tuyau détachable de la poche (pratique pour le remplissage) et système intégré permettant aux paroies de la poche de ne pas coller entre elles lorsque cette dernière est vide (séchage sans moisissures garanti). Système de fermeture et embout résistants aux fuites: un sans faute !

Everything is great about this, except that the “handle” securing the opening cannot be used to hang/secure the bladder. This means it falls down in the backpack instead of hanging, and sometimes causes the tube to pinch. Not a huge problem, but somewhat disappointing. I would still highly recommend it.
