I am 5'10, 140 lbs, skinny guy and I originally thought the fat strap would be more comfortable because I like backpacks with wider shoulder straps so I got the fat strap first. The fat strap slips off my shoulders really easily and does not have enough retention to pull mags out due to my body type. I ordered the skinny strap and now the system is flawless. Way better for my build and I guess that makes sense because it is called a skinny strap. Hopefully this helps someone else out because I am an idiot. cheers
