Few shelters evoke outdoors as much as my "Circus" tent.
A Black Diamond Megalight, it is my lightest shelter; just a glorified thin sil-nylon tarp shaped into a pyramid.

It has no floor and despite the occasional bug that might crawl in I can have a bed of flowers adorning my "living room"
It shelters me from wind and rain, and despite flapping a bit in the breeze no other shelter is as versatile or roomy as the Circus tent.

I have several other tents that totally seal me from the bugs when they are really pesky but I don't get the same feeling of being outdoors as with the floorless shelter. And when it comes to shoulder my pack with my gear and supplies for several days in the back-country I appreciate how light my shelter really is.
