Thanks for the responses, everyone!

I’ve tried an Exos and Atmos AG: Atmos fit like a pair of wings but was ironically too heavy. The Exos is really nice, too, I'm just looking to try on a few more packs before I decide.

I’d take the Mystery Ranch T-100 on a trip to the moon, maybe, but it’s way too much for my meager adventures here in the Midwest.

I’ve had my eye on the Granite Gear lineup, just can’t decide which one is for me.

The Ohm and Circuit are right up my alley, I'll make sure to check those out.

Anyone have any thoughts on the Lightning 45 or the Buttermilks?
