Never did... I like sleeping in the dirt with bugs.
I initially bought just the flysheet with the idea of using it for winter camping mainly. It is my first teepee design and I really liked it and ended up buying the nest too(which is the bathtub floor and netting). During the warmer months around here, the volume of bugs is such that you may wake up with your arms and legs eaten off, so the nest is mandatory.
Seriously, sleeping with vast quantities of spiders, ants, mosquitos, etc. crawling over my body and into my sleeping gear isn't my idea of fun, but that's just me.
GoLite no longer offers the individual components seperately, you have to order the whole outfit.
