Thank you for your comments.
Yes indeed all of our shelters go up fly first regardless if they are single or double wall.
With the double wall you can add or take away the inner (if you like....) once set up.
A good use of that is , for me for example, to gain space for an extra person or two undercover at lunch time or in the afternoon out of the rain.
because we don't have bears here in Australia it works well for cooking too.
The new Bowfin 1 could be a good choice for the OP.https://www.tarptent.com/bowfin1.html
