Customers are mixed about the ease of cleaning. Some mention that the hydration pack is easy to fill and clean because of the wide mouth. However, others say that it's not very easy to clean and hard to open to clean.
"...Cleaning is fairly easy - the hose disconnects in several places making that part easy too...." Read more

Customers have mixed opinions about the fit of the hydration pack. Some mention that it fits snugly into their pack and doesn't wiggle around, while others say that it's a little wide and wouldn't fit their pack. The top of the reservoir is wider than the bottom, and it may not fit some smaller packs.

"...We also bought an insulating sleeve for it. Was very tight to get on since this has a high flow hose which may be wider than others...." Read more
"...leaving the water in overnight and just topping off and it fits into my pack fine, it comes out and gets refilled very easily...." Read more

There was a problem filtering reviews right now. Please try again later.
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.
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. ;)
We also bought an insulating sleeve for it. Was very tight to get on since this has a high flow hose which may be wider than others.
We also bought a magnetic clip, which was a tight fit around the hose again, but worked well to hold the mouthpiece where we wanted it.
Top reviews from other countries
The opening is large making it easy to fill and easy to clean, compared to many other bladders.
The tube is quite stiff but it folds easily which makes it reduce the water flow, but if you install it correctly, this won't happen.
Comes with a clip on the tube which you can attach to your rucksack. I also bought the magnetic clip which has been working really good.
・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。
