@Kris_Smith - Is this from the most recent Kickstarter? I got notice and was debating. I’ve been very spendy lately, but I think I regret not backing it. I was going to go for the smaller version as I prefer something between 20-30L, although I don’t recall the exact size now. I’ve heard great things about these, so if you don’t mind updating after using it in the field that would be great. 
My biggest drawbacks on new bags have been price and weight, but this one is supposed to carry really well which can make a huge difference. And as you said, women-specific straps would be great.
