DRIFIRE High Performance Flame Resistant Military Ultra-Lightweight 4.5 oz. Short Sleeve Shirt Baselayers

Haven't tested the efficacy yet, just received the shirt and it is sized up for sure. I usually wear a 3X in most brands, but ordered a XXL to test the size. Fits with room to spare. Maybe too much room. It fits on me, like a 3X usually does, from brands which a XXL would suit me best, if you follow. Get a size down. Material feels nice and light, and probably will wick well compared to most natural fibers, without the easy combustion of most synthetics. Not sure I am keeping it, due to size, but as someone headed to the front line in Ukraine soon, this seems like a good option for base layer. Will update if and when FR qualities are tested.

Shirt is just like older Drifire shirts I have, this continued with the same light-weight and a comfortable feel. The coyote brown color matches other brands coyote brown undershirts that I have wearing under USAF military uniform. Only negative I though I was going to have was the large tag inside the shirt, but I never even knew it was there wearing it.

I've previously used the companies flight deck jerseys on deployment and loved them. Finally decided to spend some money and get their undershirts, only buying one to try it out due to the high price tag. I don't mind paying for product performance and quality it it's there, but light wear of the shirt, washing light detergent on delicate cycle and its already coming undone. Love the weight and breathability of the shirt but won't purchase again.

Just try one. You will never buy another undershirt for your military uniform. Five stars all around on comfort, quality, and fit. This shirt is cut for a fit person, so buy one size up if you are larger in the waist than chest.

Great product; have 5 of these shirts and worn for years. Worth the price!

Comfortable, light weight, drys fast. Good for warm/hot climates. Washes easy and doesnt carry oders like cotton and polyester.

NOT Air Force Coyote Brown. Had to return it unfortunately.

Good shirt. Collar is a littleTight.
