I really like my Kalais, as I’ve said before in these forums. But it is a tad large for short trips or winter dayhikes in Washington, where you have to be prepared for lots of different weather.
So I asked Matthew if he’d consider making a 25L pack that was a cross between the Kalais and the Aduro. Clam shell like the Aduro, but with a mesh front pocket like the Kalais. But only 24-25L main pack bag, and no frame. I really like the Kalais hipbelt, so he included a removable Kalais belt (overblown for most folks on a small pack, but I like it).
I got the pack today, and am quite pleased. I really like the black dyneema he uses, so I asked for the pack to be made of it. A couple of pics with it next to my Kalais.

With the collar extended on the Kalais. Since it’s clamshell, there is no collar on the new pack.

With Kalais collar folded under.
