I have used the Pelican Shield for many years and it is great. Outside alot and work in an environment that is not nice to phones. It is pricey but it will outlast your phone in most cases (has for me). Lifetime warranty as well but I have never had to use it.
I have dropped my pone untold times, exposed it to chemicals regularly, and water exposure is a regular occurance. Not one screen crack or issue with exposure. I keep my phones for years, I do not upgrade until the functionality is all but dead.
Absolutely recommend Pelican Shield. I do not find it bulky but I have never owned a phone without putting a case on it so I would'nt know the difference.
Also, never had a screen protector. The Shield case has been enough and I have had YUGE drops.
