I've used Empire, Dye, Custom Sports Gear, JT and Animal Paintball jerseys. The Specops jersey breathes as well as any of the others, but one problem they have is that the stitching is weak as a result of cheap thread, so what ends up happening is the elbow pads start coming loose.
I shoot a 2K5'd GZ, Excalibur, FL Viking, Texas Storm, Ripper, Ripper 2 and Ripper 3 Intimidators. I run a Halo or an Empire Reloader B (and now a Pulse) with a PMI Pure Energy or Crossfire Tank.
Lightweight breathable material perfect for woodsball.
The cost can be somewhat prohibitive.
I purchased the SpecOps Fusion Battle Jersey to have a woodsball style jersey. I've been pleased with it on several fronts. The digi camo pattern is a nice fit for the woodland varieties we have in the Northern Virginia area in the Summer and Fall. The material is lightweight and breathes well. It washes clean with relative ease and when paint hits you or someone wearing it, it'll mark clearly without staining the jersey.
The downside that I've experienced (as well as several of our friends) is that the thread used on the elbow pads is cheap and gets snagged in the woods and has a tendency to come loose. It's about the only bad design flaw in the jersey itself. I've actually seen someone get impaled by a tree and tear the jersey but the fabric didn't continue to fray after the initial tear, which I give it some props for.
The styling is simple but effective and the jersey itself is great in both warm and cold weather. Most of the guys I play with have bought these jerseys for recball play.
It's a great jersey, though the price is a bit high compared to some other tournament jerseys. It's worth the money for those playing the woodsball scene that don't want to wear heavy BDU's in warm weather.
