Ok, I walked the Nau out and around the block since our temps dropped a lot tonight - it is pretty hard to argue with the fabric. Comfy against bare skin, wicking, and SO light. I would be able to fold it up into a backpack or messenger without straining my neck. LOVE that.
This was a big lightbulb moment for me - those three things are pretty much at the top of the priorities list: soft, wicking, and LIGHT (not only for travel but also because it is not very cold here). So the NF has to go back for sure.
I may hold onto the Nau as a security blanket and wait see what the Spring lines shake loose. I have time to return later if something really wows.
