I have the Pro Pack in 70L also, I’m mixed between wanting the larger size or my set up as it is. The pack itself I really like, and I have a couple other Seal Line portage packs while my wife uses a 60L ( I think) from MEC. That was a lot cheaper but the quality is nice, plus she wanted the yellow. It has multiple grab handles which is something I notice I’ll blindly search for in my pro pack, at times. The padding on the waist and shoulder straps are very comfortable for long portages. The only downside is that I went with the olive color and wish I went orange, you need a flashlight to search the inside even in broad daylight.
