Are bivy's supposed to replace tents? Can the bivy keep out creepy crawlies like scorpions in the Arizona desert looking for something to keep warm under?
They can if you're flying solo. They usually add about 10-15 degrees of warmth (F) over sleeping in the open, and there's the added advantage of keeping rain, sun, wind, and yes, creepie-crwlies out. Plus they pack up way smaller and lighter than a tent. If you're into solo backpacking, this is the way to go.
