Hi all - Just got our Kolob packs today. Yes, plural. Love these. Woohoo! I did a quick check and they look identical to the other model. My last pack went through > 100 canyons and took a beating and survived. Comparison to the previous version? I did notice the bottom outside/side vinyl has a strong lip/seam on the top (looks even more durable) where the other version did not. And the neck around the main compartment does not have the wire going around it (which is also probably a nice improvement). Other than that, I didn't see any differences? I could have missed something, but the quality looks to be the same or better. Super pleased.
