Useful info I love the Capcap - use it on my nalgene. Sadly it diesn't fit on their 500ml bottles. Do you happen to know what the smallest Hydro flask that they work with is?
I may have to look into those. Usually I use disposable bottles when I buy Perrier or Gatorade, but I often think that a straight bottle would be nice too. I have a Kleen Kanteen but it's not insulated.Def
I just got my first Hydroflask in the mail. I love it! And the 100years guarantee is not bad either
