Best backpack ever

40L size is very flexible for multiple purpose, different destination, any season.

It is quite big enough, but also can roll down to compactly for light explore.

And surrounded by daisy-chain are awesome for your own customizes.

So far I really like the pack but need to trail test it. I changed the hip belt to the unbound belt as I like the tensioning system better.

Beautifully thought out —even an easy reach -and-grab supplies pouch at the base. Every detail is considered. Only wish it came in an XS womens. Darn.

Good upgrade

Like the big side pocket, side cord works better than Southwest, front pocket stretches at the right level.
