I lift then swing pack over shoulder with one hand by the grab handle when fully packed, & that's my scale as to how easy it feels.
I hope & try not to get to caught up in the numbers, sure I like to buy light but it's not because am trying to achieve sub whatever, I just want to have less strain on my body at the end of the day.
Base weight seems to me a competition that I have zero interest in entering. I buy things with weight in mind, after that weight is second to suitability for situation & maybe even want of comfort.
I like reading other people's gear list, the weights can look nice at times but at the end of the day someone else's pack weight is their pack weight for whatever reason & I find them neither anything to be envious over or laughable at if heavy.
I couldn't tell ye what my pack base weight is, & to be honest I really don't want to start down that path.
