I have a love hate relationship with sling packs. The one I ended up liking is the Pacsafe Venturesafe 325 in black. It's not to big or too small to carry what I need. It is a very discreet non tactical looking bag. It will fit an IPad as well. The bag is slash proof and has zipper locks to keep your stuff safe. I'm always in the hunt for a sling pack to beat this one but I haven't found one yet.
It's a nice one for sure. I use the Dsptch (https://www.dsptch.c...waist-bag-black). However, If money was no object, I think I would go for the Bagjack Sniper bag..... backjack products are so amazing.
