I bought about $1K worth of gear to do a 1200 mile self supported ultra light bike trip and the E-Bivy was about my favorite purchase. Rain in July in the western US was pretty non existent in 2012 but mosquitoes were a nightly occurrence. You can really hunker down in the E-Bivy leaving a little air hole between the top and bottom overlap material that keeps the little bastards out. The top layer does a nice job of keeping the dew off the sleeping bag. 90 degree days drys your gear off in about 15 minutes when you set up the following afternoon. This is a well considered summer piece of gear.
