[Closed] Bivvy bag with integral mattress

Now this may be a morning brain fart, but please hear me out.

I was thinking that a hooped bivvy bag with integral sleep pad (with pillow shape at the head end) would be ideal for bike packing, You could also have a midgie screen at the head end. But after a quick google, they don't seem to exist.

Pros

• Lighter overall weight, as the mattress would replace the part of the bivvy bag that would be at the bottom.
• The mattress wouldn't move around in the bivvy bag, meaning more comfort.
• Less components to carry and store, and would be quicker to setup and take down.

Cons

• If the mattress fails then the bivvy might need binning as well.
• Would be harder to make and would be more expensive. Maybe?
