Very clean Christopher. Love the monochrome color scheme.
A lot of straps as you say though, and I can pretty much guarantee you the majority of your weight is in that webbing, and all the associated hardware. Honestly considering the amount there, I'm amazed it's only 19oz.
I know that vertical swath of fabric attached to the webbing should help for very effective side compression, although I question the effectiveness of it on the front.
Seems to me though like you could be just as effective using cord on the sides (much lighter) and putting a pocket on the front?
Anyway, very professional. I'm guessing you're getting alot of PM's right now asking when you're going to start selling packs. ;)
