I'm a fairly new Ego owner and find I can fit way more in it than I can realistically carry.
I'm not the strongest individual so perhaps what I consider heavy might not be by other peoples standards.
Anyone interested in sharing their contents list AND what it weighs? This is not really about airline requirements etc, more about what people are physically happy with schlepping.
My Ego as packed in this post weighs 7.3kg (=16.1 lb)
This was my travelling office for a weekend - house to car, car to house at either end .. so not a big trek at all.
