The nyco fatigues are the same fabric used by outlier for the nyco slim pants. The green is a true fatigue green and the navy has a slight purplish hue in some light. Both fabrics have a little sheen at first but get dull over time. I found that the fabric starts to look like crap after a few machine washes. Buyer beware. It's also a little bit on the rough side in terms of handfeel.
Something about mixing the synthetic with natural fiber, or maybe its just the weave
