Ah yes, I was thinking of elastic or shock cord, that would solve any issue. This is my next step after having a floorless, TT Squall the last 8 years or so. That still allowed ants at me, the bivy should solve that. We'll see how this next step works for me out west here in the Sierra. Looking forward to half the shelter weight, I still don't know how I'll handle less bug free space to read, rest.
