Pattern disruption, breathability, comfort are excellent. Great for scenario or woodsball.
The velcro can damage them; they may let in sand, dirt, and ticks.
I used OMNIPAT ultralites all summer and had nothing but good results. Generally, they work well in semi-arid, open field, and pine forest environments. Also provide decent camo in hardwood forests. Only time they stood out a little was in green underbrush back in June.
They made humid days bearable and any breeze was felt and appreciated. I rolled down a hillside in these, shook off the dirt with no rips or tears, and played on. After crawling through wet grass, I dried off quickly. Much better than sweat soaked BDUs.
The design has the knees reinforced but not elbows or shoulders. Swab pocket, cargos with velcro closures. Velcro tends to catch fabric if not properly closed. internal belt not as useful as it seemed it would be. Internal mesh short is ok, but white back of fabric shows through some at pockets. Not cut for movement as much as I would like. Velcro cuff on pants works if you also use elastic bands from military surplus on top of boots.
I washed them a half dozen times by hand and on gentle cycle with Woolite and with dish soap. Air dry. Little to no problems except occasionally with velcro catching and with some slight wear under arm where vest chaffed.
Expensive but unique.
If you can afford to spend the money, and you play in humid or hot conditions regularly, pick these up. Don't expect them to be as indestructable as your BDUs. The design has not been perfected yet, but they do make a difference in hot games. If you play a slow, deliberate game or fixed defense, the OMNIPAT is a clear advantage. Overall, I am very happy with OMNIPAT Ultralites.
