There are a few things about vests that irk me. 1, the obvious rediculous tacticool look. 2, how do they wear loaded with a pack? that you just don't know. It may be uncomfortable as hell once you throw a 60 pound pack on over it, or worse yet the shoulder straps ride on a pocket. 3, breathability. My back already sweats like crazy on a warm day with a pack on it. How will it do when suffocated by nylon? If I got some sort of load bearing vest it would be a fisherman's style, probably a Kakadu-with 5 or 6 pockets up front and light canvas material or mesh back.
- like Fonly i dont give a rats butt what it looks like. My carrying needs outweigh the perceptions of others.
- why would you throw a 60 lb pack over a chest rig? I got my chest rig to replace my pack.
- i sweat like a pig when hiking, mostly on my back and pits. backpacks exacerbate it 100 fold. With the chest rig i can hike lite and fast, and my clothing doesn't soak out. I do get sweat on the front wher ethe chest rig sits, but its NOTHING like when i wear a pack.

EDIT: also, with the chest rig, i NEVER need to take it off, unlike a pack. Everything, and i mean everything is right there for me to access. Plus map reading is easy as the Admin panel flips down to view the map. I can run with it and it doesn't flop around like my pack, nor does it snag up on fallen timbers when i crawl under them.
