It was now lunch time and they were all sitting under the double green fly of the dining tent pretending that nothing had happened.

现在是吃午饭的时候，他们全坐在就餐帐篷的双层绿帆布帐顶下，装出什么事情也没有发生过的样子。

The Allak, from Swedish tentmaker Hilleberg, has an unusual configuration: its tent poles support the rain fly, and the sleeping compartment suspends itself from the fly (usually the tent poles support the tent, and the fly clips on top of it).
