Big Sky's Wisp tent is a single skin hybrid tent that pitches with a single trekking pole - for solo use it offers a large interior and porch for the trivial weight of just 544grams.
Big Sky says:
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.
Big Sky's Wisp Super-Bivy Tent is what we call a hybrid design, most of it is single skin but it has a fabric panel and doorway that separates the inner cabin area from the porch and external doorway. The fact that there are no poles to add weight means you can produce a spacious tent at a fraction of the weight of a two skin model with its own poleset. Look at the dimensions and you will see what I mean - the head height and floorspace is very large for one person and the porch is correspondingly large as well.
The compromise is condensation, in the most unfavourable conditions there will be a lot of condensation in the tent so you need to be comfortable with this, we are, we sell a lot of single skin tents to people who don't mind mopping up condensation in the morning.
The Wisp also comes with a short rear pole which adds minimal weight but helps with the setup of the structure.
