I have made a burrito system and to me for one rider and his/her gear is the best thing. you can make it with a light tarp for the summer and a bit thicker if is winter. I am sad I don't have any pics but next time I will make sure to take some so I can explain. The reason I do an enclosed one with a bit of netting is because of the ants, mosquitoes and other bugs that will wake you up. In the winter the cold so you want just a bit of a vent passing through but leave fairly sealed up and the warm will stay. There are tarps that have reflective material on one side you can also collect heat from a fire next to you and will keep it inside. These are also ligth. I don't have one of those but seen others use it. It is very easy to make and is faster an dlighter than a tent. I have two tents and if I am alone I am done with tents.
