Not sure I'd trust this in the Himalayas, or even the Pennines... but it's absolutely adorable!
The completed bag weighs 17oz. Far lighter than my expectations.
I made sure to include a sleeve that I could slide a Zlite sleeping pad into. This acts as a frame and stiffener, and also as a cushion from the items that you are carrying.
The total cost of the pack was about $30, and a lot of time, but that is part of the fun.
