Customers are mixed about the leakage of the hydration pack. Some mention that it's durable, tough, and doesn't leak, while others say that it leaked all over inside their pack. The reservoir and access water dripped out the bottom of the backpack all down their back and butt. It has delaminated and started leaking around the clip that holds the hose to the pack.

16 customers mention11 positive5 negative

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

"...I also find it easier to open, fill, and clean than CamelBaks." Read more

"...Compared to a bottle, it's definitely a hassle to clean a water bladder, although this design is easier than those with a screw cap...." Read more

11 customers mention4 positive7 negative

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. It's also very tight to get on and awkward to try to keep a grip on it while holding the mouth of the bladder open.

"...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

"Not a review on use since it wouldn't fit my pack. The top of the reservoir is wider than the bottom and didn't fit right...." Read more

"...I like the cinching because it makes it easier to fit in the pack without getting too big in the middle so you can fit more stuff in your pack...." Read more

5.0 out of 5 stars これなら使えそう
Reviewed in Japan on March 23, 2024
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。
