tem Number: Wisp-1P - 1 Person - single wall tent - trekking pole tent - only one (1) trekking pole required The Wisp is well suited as a bivy replacement. Think of it as a "super bivy" since the Wisp is totally enclosed to escape bugs and mosquitoes, it is also big enough to be able to sit up in and change clothes when it is raining, which is impossible to do with a bivy. Another bonus is the Wisp has a covered vestibule that a bivy does not have to store pack and footwear out of the weather.
