My girlfriends brother who is a 30 year career Army Special Forces informed me of these two vendors who supply clothing and gear to the Army and other branches. Very nice stuff. A little pricey but I am sure it is worth it.
Triple Aught Design Gear, Inc.
The TAD Gear website is a little difficult to navigate but spend a few minutes there and you'll figure it out. Lots of good stuff. I especially like the pants they offer at TAD.
Amron International, Inc - Commercial Diving, Law Enforcement, Hyperbaric Chambers, and Tactical Equipment Supplier
The Amron International site is more straight forward. If you look on the left margin for a link called "Tactical Equipment" you will find what you are looking for. The jackets look AWESOME but at nearly $600 each they should be.
Check these sites out and let me know what you think...
