As seen in this sneak peek, which is exclusive to The Hollywood Reporter, the designers' reactions are decidedly mixed.

"I absolutely hate being outdoors. … And these mosquitoes are getting on my nerves," declares Ken Laurence.

On the other hand, Jeremy Brandrick enthuses: "I'm very excited. I want to walk around; I want to paddle in the stream, let the environment take me. I want to do everything."
