Great product
Perfect for my need

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.

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.

Like much better than hard plastic handhelds
Bought this bottle to use in a hydration vest but carried it by hand one day. Wish I had bought the one with handheld unit so it’d be more versatile. Was difficult to keep in my hand for an extended period of time and it was too large to fit in pocket.

Best for hiking.
Purchased two for my husband and I. I think it's OK for walking and hiking.

The bite cap is bigger now than previous models
The bite cap is wider now and a bit uncomfortable in my mouth compared to the previous Nathan Flasks of 2022 or 2023

Best 20oz Bottle on the Market
The manufacturer of this bottle makes a generic one that you can sometimes find for a few dollars cheaper - buy this instead, its worth the few extra dollars. It has a one click to lock the top which eliminates any leaking and is slightly thicker than any generic type, so it will hold up well.

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。

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。

このフラスクばかり使用しています。
キャップにロック機能が有り、不意なドリンク漏れが無く便利。 またキャップの径も大きく比較的洗いやすい。

Excelente sustitución de Botellas
Un poco mas de capacidad que la original del cinturón Nathan, también compatible con las bolsas frontales de chalecos Salomon y UD
