For my birthday last year, my very thoughtful mom hooked me up with four months of Cairn, which I have been meaning to talk about. Have you tried it? My short review is that it’s awesome.
One of my favorite things came in the first box: a collapsible Hydaway bottle.
It’s the perfect collapsible bottle, in my opinion. When I climbed Mt. Whitney in 2015, I loaded up on these plastic bottles, all of which eventually sprung a leak after just a few uses. The Hydaway is made of silicone and feels much sturdier than those flimsy things.
If you wan to hook it to your pack, it has a handle on the lid. If you have any water left when you’re done, the 21 oz. size (the largest one, which is what Cairn sent) will fit neatly into your cup holder.
The wide mouth makes it easy to clean, and it’s dishwasher safe if you put it on the top rack. When you’re done using it, it collapses completely flat.
It also comes in handy at the airport, where you’re forced to lug around an empty bottle that does nothing but take up space until you get through security and can fill it up. Now to can drop the Hydaway into your bag and not worry about it until you need it.
