For you police, fire or EMS types that have swallowed the iKoolaid, there are some nifty apps to be found over on tacticalpants.com, a purveyor of, oddly enough, tactical pants.
Or, as TOTWTYTR refers to them, “action-adventure pants.”
FTC Disclaimer: I have no financial relationship with Tactical Pants (although I’ll gladly accept any free schwag, hint hint). Just passing along some nifty stuff for someone on my reciprocal blogroll.
