TigerMKA-K036KK Mug Bottle, 12.2 fl oz (360 ml), One-Touch, Lightweight, Stainless Steel, Vacuum Insulated, Hot & Cold Retention, Black

This works great and fits my unique requirements for a cupholder on the Airbus A330 which is only 6.7cm in diameter. Note this is the same diameter as a standard US soda can. The picture is another similar brand, but the Tiger works as well.The downside of the Tiger mugs is that they are sometimes only available for shipping from Japan which takes a while and it they can be more expansive then the similar Zojirushi versions. The Zojirushi has a latch that is a little taller and touches the lower part of your lip while drinking - a minor annoyance. However, it makes me a little more likely to recommend the Tiger, but only if the delivery and price are similar.

保温がすごくいいです

One of my best insulated flasks purchases ever! The flip top is convenient and leak proof. Best thing is that the insulation is out of this world: Iced water keeps cold for over 24 hours because the ice remains as ice for that amount of time!

今まで出先でコーヒーなど飲む時はお店で買ってたけど、節約とエコを考えて初めて水筒を購入。保温性の高さに驚きました。朝8時入れたコーヒーが夕方6時になっても美味しく飲めるくらい温かい！逆に、最初の2〜3時間は熱くて火傷しそう笑。 容量は360mlは少ないかなと思いましたが小さいバッグにもコンパクトに収まるし、冬のホットドリンクをちびちび飲むにはちょうど良かったです。出張や実家に帰る時の移動などにぴったり。スクリュータイプの水筒とどっちがいいのか迷いましたが、飲み口が大きいとこぼすの怖いなと思いこちらに。ワンタッチは片手でサッと飲めるしやっぱり便利です。漏れも一切なし。色使いや表面のザラっとした質感がハイドロフラスクっぽくてオシャレ。パーツも最小限で、洗うのも楽です。買ってよかったー！

調度いい持ちやすさで、洗いやすくて、飲みやすい!

形も保温性も申し分ないです。600mlで仕事中飲むのにちょうどいいです。
