Field and Trek has a sale on Deuter packs. I had a Futura 32 but the air flow back was wasting a lot of space inside and it was a bit too short for me at 5’10. Now have a ACT Trail 32 and it’s perfect. Many pockets, well thought out design, usable on the bike as well. Very comfy back and harness with extra zip in the middle so You can get inside easier. It has a integrated rain cover which works very well.
I can also recommend an Osprey Kestrel. I had a 38 and it was huuuge. The 28L version looks like a typical 30-32L rucksack. Good harness, comfy and well thought out. Integrated rain cover but Deuter has more pockets so I can organise stuff better.
I borrowed my friends TNF Terra 30 once for a trip and although TNF gear is not the STW favourite brand choice the rucksack was very well made and really comfy.
After trying different models I think my current Deuter ACT Trail 32 is the best, it would be perfect if it would have a zipped divider in the main chamber like the Futura 32 did.
