MR is just another backpack company that makes a great product until you put more than 60 Lbs in it.
As funny as reading about bullet failures.
Oh, I didn't say that a MR pack COULDN'T do it... But if you put 100 pounds in a NICE frame AND a Kifaru UL5200, or Timberline, it sucks a WHOLE LOT LESS.
Seriously... I'll let you borrow it sometime. I'll be shocked if you don't agree.
