Before deploying in 2010, I did some research looking for a uniform with an effective desert pattern. ACU's just don't cut it, as the Army has had to reluctantly admit only after Congressional intervention. The Marines have a pretty decent desert uniform but wearing that might constitute perpetrating a fraud in the eyes of a Marine (I was Army) so I ordered a few uniforms from Hyperstealth Biotechnology Corp.
The uniform is from their SPEC4CE series and is called Desert Dune. The cut is similar to the ACU and other modern US military uniforms with pockets on the sleeves and ankles. One noticeable difference is the lack of velcro, most of it being replaced with old school buttons. The pattern itself is a four color digital type which worked very well out in the hinterlands.
The lightweight fabric used was MUCH appreciated come summer time in Iraq. This uniform was much more comfortable then ACU's, DCU's, and a Multicam uniform I had from Propper. The trade off is that the lightweight fabric is more prone to rips and tears. In the Iraqi summer heat I was happy to accept that and engage in a little Suzy homemaker stitching post-mission when needed.
I would wholeheartedly recommend this uniform to soldiers currently deploying overseas if they can manage to get their hands on it. Hyperstealth does limited commercial runs but it is certainly worth looking into.
