These German/French issue tricot shirts are three types of blended cotton (breaths much better than average cotton). 

I have now worn this shirt (fits damn true to size as well) for countless ruck marches, training events, hikes, runs, gym lifts, a bushcrafting event, and a land navigation event. Probably my favorite shirt I own. 

These shirts are FAR more comfortable than they should be. Doesn’t even make sense. They breathe surprisingly well too. 

The vast majority of them are mostly true Ranger green. You may get a slightly different shade but these should be mostly Ranger green.

For the price? You can not beat these.
