Every time I look at various options I come back to the lean shelters from Cooke Custom Sewing.

I am nearly always in a forested area so trees are available for guy lines. Lots of room like a tarp, closed in sides and an awning for a bit more weather protection, less weight for the interior room than a tent. What's not to like? (Other than I don't have $250 burning a hole in my pocket at this particular moment in time.)
