double wall tent
- Double Wall Tent
One that has a rain fly over the tent itself.
The rain fly repels rain and dew, and the inner, breathable tent walls comprise the tent itself.
Heavier, costlier (generally), and more complex than than single wall tents, they are also easier to manage in extremely wet conditions.
My double wall tent is more than twice as heavy as my single wall tent, but more comfy.
