For sale is a Nunatak Arc Specialist, size small. This is a catch and release for me, just a little too small. I bought it here and would like to sell it for what I paid, $225.
The inside of the bag is black and the outside green. There's a tag that reads Pertex Quantum, and according to my scale and the specs on the Nunatak website, its the lightest variety of pertex they offer,.8 I believe.

I'll update this thread later with photos and a link to the original sale thread. I notice one small pulled thread, other than that the bag seems to be in perfect shape.
