I have been a cop for 33 years. I now walk a foot beat and carry 27lbs of gear in the summer… I actually can feel a breeze crawling up my front and back! I now go home less sweaty and have more energy at work.

I was skeptical at first but after wearing the vest I highly recommend. I showed my sheriff and deputies and the department is now buying everyone one of these vests.

It's been 90 everyday since the Maxx-Dri vest arrived. I used to have heat rash and a smelly vest at the end of the day. Now it feels like it's 75 and my ballistic vest is nearly dry.
Brad G.Advanced -
I tried it outdoors a few times in the Florida heat with a plate carrier and plates and the stand off it provided really does make the difference.
Guy M.Elite -
My vest no longer smells!!!! It was affordable, built with great materials, easy to wear.

I purchased the 3.0 in 2017 and it was an absolute game changer. I've never had another heat-rash since owning it! It also held up great.

Questions
Does it work with concealable armor and plate carriers?
Yes. Maxx-Dri sits between your base layer and your armor, whether that's an external plate carrier or soft armor under your uniform shirt.
Will it add bulk?
Not in any way you'll notice. The 3D spacer layer is ultra-thin and light. As one officer put it: "The added bulk isn't even noticeable, but the airflow and comfort it provides are second to none."
Can my department buy in bulk?
Yes. MDV10 takes 10% off 3–4 vests, MDV15 takes 15% off 5–49. For 50+, email sales@221btactical.com for a quote.
