Good points, MassiveD. I should've been more clear that this is a decidedly race-oriented rig with a commitment to going light, fast, and resupplying ~daily (for the TD at least). So yeah, perhaps not suited for typical touring (whatever that is) but I think the trend towards leaner and lighter kits is probably beneficial for the full spectrum of use cases.

Similar to your backpacking analogy - fewer people are going for the conventional approach of 6,000ci, 6# bomb-proof packs anymore, and that's good. (I thru-hiked the Appalachian Trail with a 10# base weight 10 years ago, so I don't mean to imply that any of these are "snazzy new systems.")

To your point about capacity, I had this 3.6oz cuben backpack in my kit to deploy as needed (eg, the Basin in Wyoming, etc). I'd put light fluffy layers in there and the extra food + drinks would go in my Viscacha seat bag.

Anyway, I mostly intended that pic as an example of the kind of rackless options that the other commenters had been encouraging the OP to look into.
