I didn't find the F-stop suspension system anything special, at least on their biggest Satori bag. It certainly wasn't any better than my Gura Gear Kiboko bag, which holds considerably more *camera* gear than the F-Stop XL ICU. I've carried 50+ lbs in the Kiboko, and while it wasn't awful, I was relieved to take it off after 5 hours of hiking. I returned the Satori bag, but kept the ICUs (I got the XL, and L ICUs) because they work nicely with my 65-75 liter Gregory Baltoro hiking bag (which offers comparable access to the ICUs) but with a far superior suspension system.
I'm a bit annoyed with F-Stop because I also ordered the medium size ICU at the same time as the other gear, and was initially told I could expect delivery in mid-June. I've had to follow up every month since then to get updates and am continually disappointed to learn that "it's a month away". The latest response I got (a couple of days ago) was:
"We sent out an email to everyone with pre-orders 2 1/2 weeks ago, it might of gotten mixed up in your junk folder. Regardless, the Medium ICU will be available along with our new Loka Back Pack at the end of August."
Sorry, but it wasn't "mixed up" in my junk folder because it was never sent to me. I understand the fact that this is a new, small company, but I don't like excuses, false promises and just plain BS.
