I bought a Civita day pack and after a couple of small modifications, I love it!
At home, I carry a water bottle pretty much everywhere I go. The one I have now is an h2go 20.9 oz aluminum bottle that was SWAG my wife got from her company (it has the company logo on it). BUT, it's nearly 12 inches tall and a bit less than 3 inches diameter. If I put it in the water bottle pocket on the Civita, it falls right out.
In the picture on the website here, it looks like it's shown with the RS aluminum 500ml bottle, but that is out of stock.
If you have a Civita, what water bottle do you use with it?
