It’s a floorless two person tarp tent. Great review here: https://sectionhiker.com/mountainsmith-mountain-shelter-lt-tarp-review/

This one has a DIY stovejack on it.

It’s been raining here…forever, so I can’t put it up here now, but I’ll upload better pics tomorrow.

It’s in great shape. Super cool and roomy shelter for two people or one person and a dog or one person and a stove.
