## Description

Simple silhouette, eye-catching clean coloring is fashionable design you want to use every day. Cold beverages are 24 hours and hot beverages are 6 hours, long lasting thermal and cold effects. Prevents flavoring and keeps your drink tasty. The cap has a strap for easy carrying. Enough capacity for gym, yoga or other occasions that require hydration. Material: Body: 18/8 stainless steel (printed steel plate) Lid: Polypropylene Packing: Silicone Strap: TPE Size: Volume: 24.4 fl oz (621 ml) Diameter: 1.9 inches (48.5 mm) Product Dimensions (W x H): 2.87 x 9.1 inches (73 x 240 mm) Weight: 13.4 oz (340 g)

Review: 値段は高めですが、朝入れた暖かい飲みものが夜まで温度を保てます。冷たい飲み物も同様、保温・保冷がすごい！重さは結構ありますがデザインも良いです。
Review: 見た目にもかっこよく、家庭用の氷も半日くらいでしたら溶けないくらい保冷力も素晴らしいです。 大きいのがほしかったので期待通りの活躍です。 普段会社に持っていく、、には少し重いかと思いますが、休日のアウトドアやスポーツ観戦でリュックに入れていくにはとてもよいと思います。 この値段出しても十分満足できるものでしたが、上島珈琲では持ち込みで-50円ですので、少しずつ回収していっているのでそこも嬉しくてよけいに使い続けられています。

## Questions & Answers

**Q: Re Hydro Flask 24", what does "flex lid" mean?**
A: no, you can't. if you watch the video it shows that you have to remove the lid to drink. i think the "flex" is in fact that the handle folds down, instead of being "fixed".  you can get a lid that has a pop-up straw.

**Q: Ok so does it come with little stickers?**
A: Hi - Wendy here from Tall Ridge, the exclusive authorized seller of Hydro Flask products on Amazon - Thank you for your inquiry! Our Hydro Flask products do not come with stickers. I hope that answers your question.

**Q: Curious... is the bottle supposed to be perfectly round all the way up and down?  i just received mine from amazon and it is not.  it feels oblong.**
A: Yes, it should be perfectly cylindrical (round) all the way up. If it's not, there is an issue, and I would think that the company would take care of it. To tell if it's in fact round, remove the cap, make sure it's empty, place it on its side on a flat surface, and roll it.

**Q: I just bought this hydroflask in the color olive. Is it normal for the lid to have to be forced to close all the way? It doesnt close easily**
A: How did this work out for you? I'm experiencing same problem? I know it's not normal as I have been using this brand for a couple years now. Did u keep and use?
