I wanted to take a few moments to share some of the things I have been working thur on backpack fit.
I have a unaweep with 4800 bag and a EVO frame.
I was having problems getting the shoulder harness system to work for me on these packs.
What I have found that works for me is as follows.
Put the U of the shoulder harness 1.5 to 2 inches below you c7 at back of neck.
If the harness is to high or to low you will have problems.
I was also wearing my hip belt to tight.
What I do now to adjust my pack when I put it on is this.
I first tighen my hip belt. Then the shoulder straps but not to tight. THen the sternum strap then lightly pull in the load lifters.
The pack should move a small amount up top when you walk.
I am very happy with this system now that I got it working for me.
Don't give up on these packs if you have one. THe belt is great on these packs and load lifters also.
THe shoulder harness system is good when you get it adjusted to work for you. It only takes a little to change alot when it comes to the harness system.
The only thing I can see that might work out better on these systems for me would be the shoulder straps could be a inch or so longer.
Thanks and once again this is whats working for me hope this helps someone out.
