Best mid-sized pack I've ever had. Kept searching for the right pack for three months. I don't usually post Amazon reviews, but this well-designed, quality thing deserved it.Pros:Rides like a dream. Carries 35-40 lbs of heavy camera gear so, so well. I've never had a pack ride so well.The large version fits a 6'1" person like me wonderfully.Hip belt adjusts smoothly, nice padding.I like the "Airspeed Suspension" mesh back for air flow to keep sweating reduced.Durable fabric. It'll get scuffed but it seems tough and able to last 20+ years if you take care of it.Nice to have a rain cover embedded in the bottom. I love that feature on LowePro camera bags.The trekking pole attachment is useful, I suppose. I haven't needed it too much.If you don't pack the brain and don't overstuff the mains, my large version fits just right in an Airbus 320 overhead compartment. This tickled me pink. I didn't think I'd succeed at this, given the dimensions exceed what most airlines supposedly tolerate, but it fit.Cons:I docked a star because of that godawful toggle system with a flat cord to access the main compartment requires two hands and is still annoying every. darn. time. you need something. Real PITA when it's dark and you need to shuffle gear around or if you need a hand free to hold something. Easy fix to move this from four to five stars: I got a normal toggle for cheap.I wish the bottom compartment and the front panel storage compartment were larger. You won't get bigger sleeping bags in the former without a serious fight, if at all. I can get a drysack of winter jacket/gloves/hat/etc in there but it's a bit tricky to zip.A bit heavier than I'd like but a bit over 3 lbs is still pretty good for the durability of fabric.The zip pockets are a bit small. I'm not going to fit a Pixel 4a for 5G with a case in there. Candybars and keys, okay.Colors: the orange was brighter/shinier than I expected. Not my thing. Maybe you'd like that for hunting season or search and rescue if hurt, but I returned it for the better-looking black version. I didn't want to stand out more than I already do when overseas.Would absolutely buy again if lost or stolen. Preferably a newer version without that infernal toggle design.
