Bivvy Ledge Setup

Thinking about big wall routes that have good size ledges, using a bivvy setup, how does one secure themselves to the anchor when inside the bivvy zipped up lol 

It may be a stupid question, but I can’t picture it

thanks!

Yeah, it’s pretty obvious. You’re sleeping with your harness or a “sleeping sling” and you’re tied in. The rope runs down from your anchor into your bivy sac and sleeping bag.

That’s what I thought. Just seems counter intuitive to have a bivvy sack that’s supposed to be closed and leaving a hole for the rope to go out. Guess it’s good for venting too lol

thanks!

If you want to be super waterproof:

^^ I have this bivy sack. It will keep you dry. However the through-the-side-wall clip in system is total Big Wall Theory. 

Have a bunch of slings girth hitched together, and run them through the same way you climb in. 

You know, a double length sling used to tie round my waist quite easily, but not any more. I guess they are making them smaller these days. 

The Integral Designs Salathe Bivy Sack had the best design for staying tethered while sleeping.  A bit on the heavy side but worth it.  

I think it was Andy KP that clipped himself to his biggest stopper, pressed it against the fabric inside his bivy bag and girth hitched it from the outside with a sling to the anchor.

I remember seeing a picture similar to that, of a bivy on Changabang in Climbing magazine (probably 96 or 97).
