Pack re-works..

 The leather/antalet chest strap works great.

I refined the chest strap design with some lengths of thin rope to prevent it from sliding down the shoulder straps..

The straps on the Exped Thunder are kinda skinny and tend to roll/fold so I added some old felt pads from a old Haglöfs kids backpack.. If it works I'll out a stitch in it to make it a "permanent fix"

Love this pack, great for +15-20 kg loads..
