Familiarity: I've used it several times
I've gone through several bags in my lifetime, but this one is definitely the most uncomfortable. It's too bad - I was stoked to receive this. The big lower back "pad/knob" that is the centerpiece of their "ergoactiv" system is horribly uncomfortable. It just digs into your lower back, and rubs around constantly causing a lot of discomfort, soreness and chaffing. After about 30 mins of hiking it just feels like a hard knot. The shoulder straps are also very thin and barely padded. Honestly, it's a horrible design - one that I believe is providing a solution to a problem that never existed. Traditional non waist rotating backpacks are WAY more comfortable than this. I've put 30lb in this pack and taken it a total of 18 miles since I got it, and I wouldn't go another mile with this thing. In fact, I just bought (for $99 on sale locally) a Deuter Guide Lite 32+ to replace this and it is incredibly comfortable. Deuter knows comfort. Black Diamond could learn a thing or two from them. I'm sending this back this week. Do yourself a favor and avoid this bag and go with Deuter - they are unbeatable in terms of function and comfort.
