Hambunking is the stacking of two hammocks on the same suspension set. So the longer hammock goes on the bottom, and the shorter hammock goes on top. Two people can sleep very close to each other in this setup.
The xPlor and the Solo will fit inside the Ninox Hammock, and you can hambunk these products.
The Pares will not hambunk with the Ninox while the xPlor and the Pares hambunk really well.
The Solo and the Pares are a bit too tight to hambunk though.
