It’s cool but I felt like it coulda been better. Felt like it helped cool me off better once I got into the AC car but almost feels like it still gets hot with no difference

Highly recommended from someone always outside on foot patrols

Took a few days to get used to having a little extra bulk. At first I didn’t think it was doing much good since I am still pouring sweat, so after a few days of wearing it, I worked a shift without it. That was a horrible shift. I was missing the max dri system. After not wearing it for a night, I could definitely tell that it does work. Keeps core temps down, keeps the vest dryer but still have some dampness. The shirt that came with the max dri system is a tad thinner than a normal under armor cool shirt and I can tell that it allows more air flow. I work security for government housing projects in Oklahoma. Very hot out and I’m always outside on foot patrols, climbing stairs, on calls and very busy. I have used the tacvent system in past and it works well, but I think it works better with plate carrier vest, not a full body armor panel vest. The max dri is an excellent system and I am very happy with my purchase. Vest smells better, it’s not a wet at end of shift. It’s not a miracle working system, so don’t expect it to be an air conditioning system. If I had to guess, under my vest is around 15-20 degrees cooler. What I like the best is after a good long foot beat, get into a vehicle with a/c or office and you’ll feel the cold air flowing under the vest.

Highly recommend the max dri 4.0 system paired with the shirt they sell. 5 stars for me.

Thanks for your comprehensive review Gary! It will surely help others as they contemplate considering to invest in this system, just as you did. Much appreciated! - Brad @221B

Quality Product

Working 12 hour shifts before this product I was sweating like there was no tomorrow. After this product much of the excess heat went away. Would highly recommend to LEO!!!

Product does as it says

I was skeptical, however all the reviews where positive. Tried it out and was pleasantly surprised. Air was circulating under my plate carrier and kept me cool. Also, the Silver Elite Shirt also helped with keeping me cool so as a system they work hand and hand. Highly recommend!

Maxx Dri 4.0 Silver Elite Anti-odour rash system

Several of my co-workers wear versions of the Maxx Dri 4.0, they work very well in keeping the airflow going behind the vest. I Run warm, very warm so this was a no brainer to buy. Looking forward to running the silver elite t-shirt to see how it stands up!
