Make sure you have a good sleeping bag or top quilt and a pad or an underquilt.
Sleeping pad: There are a lot of different sleeping pads out there; some are even designed to be used in hammocks like Segl XL. A simple foam pad, reindeer skin, or similar will also work. We hope you´ll find what works best for you.
Underquilt: To be attached under your hammock as a replacement for sleeping pads etc. There are countless models available. Google it;)
