旧バージョンと両方持ってますが、新しい方が飲み方が薄いので飲み心地がいいですね。ややサイズ感は増してる印象。

元々はSnow Peakのチタン製マグ断熱タイプ)をキャンプと登山に使っていたのですが、①嵩張って邪魔、②コーヒーがすぐ冷める、に悩んでました。そこへ本品を知り購入した所、見事にコンパクトでマグの持ち運びのお悩み一発解消でした。冷めやすさは魔法瓶では無いものの、シリコンは熱伝導率が低いのか特別悪くなった様な気はしません。一部匂いが気になるとの投稿がありますが、私の場合、最初に使う前に丹念に洗ったら全く気になりませんでしたよ。(届いた直後は確かに匂います)超オススメです！

This is a great cup. I've used it for cold and hot liquids. It packs away very small. Perfect for travel. I would buy this cup again if it was lost.

As a owner of the x-cup, I felt it was too small (8 oz). Hard to mix anything in it and not stable enough. This frontier model is a big improvement. Love the hard plastic rings which give it way more rigidness and stability. Also the 12 oz size makes it way easier for mixing drink powder etc. The icing on the cake for this model is the weight! Only 1.8 oz on my scale.

Nice color. Pops open/close easy but sturdy enough not to collapse on its own. Only thing is dust/dirt does stick to the silicone.

This cup was in constant use while staying in the home of someone in Italy for a month. I used it to mix up my protein supplement which I use every day, for general water intake and then would keep it by my bed at night. Easy to clean and unbreakable. And, carrying it in luggage was a breeze since it folded down. Excellent product!

Sea to Summit ist für mich die Marke, wenn es um das Reisen geht. Die Firma legt größten Wert auf geringes Gewicht ihrer Produkte, allerdings mit hervorragender Qualität. So auch dieser Faltbecher.Sehr gut

I tried a couple other options from Amazon and all were too flimsy to be able to hold a cup of water. Folding and unfolding ended up being a mess.This cup is the opposite, it’s very sturdy because it’s made out of more than just silicone. It folds easily I can fold and unfold it with one hand if needed.Most of all it can hold a full cup of water.
