I like having the bugnet as part of the hammock. I also treat my hammock and the attached bugnet with permethrin once a season. There is never a time I do not use the bugnet. I still use the bugnet even in winter. The netting does trap some heat. Enough so that condensation appears on the netting and off my down quilt. When i unzip the netting, I can feel a rush of colder air.
