So I opted out of purchasing the winter top cover when I first purchased my Blackbird XLC, and regretted it as soon as I received my hammock. My first trip out with the Warbonnet Blackbird was in the winter and I had to get creative to trap heat when I was sleeping. I was in communication with Brandon from Warbonnet Outdoors and asked if it was impossible to order a winter top cover after having already received my Blackbird. His response, "not impossible".
I was told that depending on when I purchased my XLC would determine if I could add the winter top. The Blackbird XLC has a continuous zipper that goes around the entire hammock which allows for removal of the bug net and swapping out for the top cover. These zippers need to be the same make in order for this to be possible.
Removing the bug net and adding the top cover was very easy. I simply laid it out on the floor of my bedroom and paid notice to where the shelf was located. Make sure to disconnect the toggles at either end of the hammock before zipping on the top. The zipper is single direction so it's not that confusing.
Watch video below for my initial thoughts.
