You are going to have to build a third garage for all your gear mate, because your other two will be chockas.
I have been carrying a haversack by Bush Track, for both work and bushcrafting for the past six months. It is a fairly basic, single tub.
It is made in India and distributed out of Melbourne. I bought it from my local camping shop for $9 (l think).
Day to day, I carry my water bottle, my Go Pro and a small bag with a spare battery and some other odds and sods, a notebook and pen, a small drawstring bag with my keys and a torch.
I am prototyping a techno-medieval wayfarer type rig. My recent dry foods challenge was intended to fit in the haversack, along with part of my cooking set up.
I think I am going to have to do a separate write-up on this.
Either way, for a fairly small bag, it carries a heap of gear.
My point is I totally rate my haversack. It has been a great addition to my bushcrafting kit.
Cheers
