I purchased the Aura 50 in 2012, so I have the older purple model, but it’s the same basic setup. I’ve used it for small backpacking trips, as well as my 2016 5.5 month thruhike of the AT.
|50-liter size is perfect for not letting you carry too much weight||
|Comfy, padded straps and hip belt||With long, sweaty distances, you will always have rubbing (I got packrash, but not the worst case I saw)|
|Big stretchy side pockets||They get REALLY tight when your pack is full, so it’s hard to put stuff in them while it’s strapped to your back|
|Reservoir holder fits Camelbak, MSR, etc.||Improvement request: external bladder section (like many of my male friends’ packs) so I don’t have to unpack everything when I fill the bladder|
|Hip pockets were handy for fitting my SPOT GPS, pocket knife, watch face, etc.||Smaller than other model hip belt pockets (newer Auras do have bigger pockets)|
I put my sleeping bags (winter, then summer) in a compression sack in the bottom of my pack, and secured my sleeping pad on the bottom external straps. This was handy as it made my pack a kind of chairback when I took breaks.
As with any long-distance hike over many months, the pack (especially straps) were SERIOUSLY funky after a while. After multiple washings, it still smells, but all packs will do that.
