The FD issues us TruSpecs. I have only worn mine a handful of times, because I prefer the EMS pants, but they seem like they are decent pants. Most of the guys I work with seem to like them.
I've got a pair of "Brigade QM" EMS BDU's (probably almost the same as the Tru-Spec EMS BDU's)... I like them, with 2 reservations.
1. Velcro on the cargo pockets doesn't really work - it isn't sturdy enough to hold the large pocket closed like a button.
2. The lightweight fabric is a blessing and a curse... they are great "summer-weight" pants, but I wouldn't want to wear them without long underwear in the winter... that is a problem with the lightweight cotton twill pants.
