Exped Bivy Poncho UL
Here's what other sites are saying:
Exped's Bivy Poncho UL can be connected with several other Bivy Ponchos to form an expanded shelter, and the integrated chest pocket forms a stuff sack.
Why carry more than you need to? Exped's Bivy-Poncho UL is a rain shelter that not only protects you on the trail but when you want to hunker down for the night too. Its unique design allows it to be used over a backpack when you are on the move with snaps, cinches, and a waist belt and a tarp shelter at night with multiple guy out points. When it needs to go back in your pack, just stuff it into its own pocket that can be used to create ambient light in your tent by simply dropping a headlamp into it.
