水漏れ防止機能他
丈が短めなのに容量はある。短いサイズだとトレランザックからも落ちません。使わないときに圧で押されて中味が出ないようストッパー機能(ボトル蓋と飲み口の間に回すだけで取り扱いしやすい)もあります。再購入必須の品物です。

Perfect backpacking water bottle
A new must have for my backpacking gear. I use a CamelBak for my water but wanted something I could add electrolytes to and this is perfect. I don't go fully ultralight, but pretty light weight. This collapsible flask is perfect for a light weight water bottle that compacts down to almost nothing when it's empty. I've had it on 2 easy backpacking trips already totalling 10 nights. 2 more trips coming up to finish off the summer.Does not leak. No bad taste even the first time using it. So far it seems very durable and I'm sure I'll replace it if it ever wears out.Highly recommend.

Love the twist to lock
These are great flasks that twist and lock when needed. I usually store one in the back of my running vest, and I can be confident that it won’t leak bc of the locking system.I prefer these over bladders.I’ve had a set of these that I’ve used for years, and just bought these extra ones a longer event.

大容量でいい
元々1本持っていたがレースの必携品のために購入。他メーカーのフラスクだとキャップが付いてることがあるがこちらは無いから飲みやすい。また容量も600ml入るのでペットボトルから移し替えるときも全量入るのが良い。
