I ordered a skin from bestskinsever.com ...their "Glossy - Full Wrap" version that covers the back and sides of the phone (should be here today or tomorrow).
Though their matte finish looks better, IMHO, it's not as grippy. I used their matte finish on my 5s but ended up going with a case anyway because it still felt slick. For my iPhone 4s, I used their glossy version with no case for 2 years, as it had just enough stickiness for me. The skin lasted about a year and a half before becoming yellow and peeling and needing replacement. Never dropped my 4s in those 2 years either...YMMV. My 4s was my favorite.
The skins are inexpensive too. They have/had a sale where I paid just $6.74 each.
