Nemo Tenshi (after they fixed the PU issue). Bought in 2014 and only used a few times each winter! It’s super bomber and comes with everything that was standard (guy lines, stakes, condensation curtain, etc). Asking $400 obo. Will ship, but would prefer in person here in Colorado. The closer you are, the more willing I am to negotiate.

It has only been used in snow, and it is seam-sealed.
