When ordering outside of United States of America, the recipient is responsible for assuring the product can be legally imported to the destination country.

The recipient is the importer of record and must comply with all laws and regulations of the destination country. The recipient of an international shipment may be subject to import taxes, customs duties and fees, which are imposed once a shipment reaches the recipient's country. Additional charges for customs clearance must be fulfilled by the recipient. 221B Tactical has no control over these charges, nor can predict what they may be.

Customs, duties, and taxes are non-refundable: so a shipment that is refused because of unexpected import fees, the cost of the original shipping and any return shipping charges will not be refunded. Customs policies vary widely from country to country; you should contact your local customs office for more information. When customs clearance procedures are required, it can cause delays beyond our original delivery estimates.

To avoid a delay in receiving your order from customs, we strongly suggest:

  • Providing a phone number where you can be reached by customs when your product arrives. This phone number will be listed on the commercial invoice so customs can reach you to clear your order.
  • Please do not refuse a shipment or ignore requests from carriers regarding duty and/or tax liability charges. Be aware that most carriers will hold a shipment for 5 days after arrival in your country before they return it to the sender.

We do not refund original shipping charges for goods that are refused for delivery at customs.

Maxx-Dri Vest ("MDV") is a revolutionary product that makes wearing body armor more bearable. Some 300,000 police, military, and other wearers of body armor have embraced Maxx-Dri Vest since we launched version 1.0 a decade ago as the flagship product in the founding of 221B Tactical. On the 10th Anniversary of MDV, we launch the newest and best, the 5th generation Maxx-Dri Vest 5.0.

MDV’s many thousands of ecstatic reviews testify that it not only works: It works brilliantly. Many MDV users call it, "a game changer!"

"It Really Works. The vest itself is quite lightweight, but very well made....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 in keeping you a bit cooler. Definitely worth the money if you live in a warm environment." —Guy McCardle Jr. (May 3, 2024)

MDV’s patented ultra-lightweight 3D material separates your base-layer shirt from your body armor vest. We call this, "creating a layer of space” between your armor and your body. It lets the body breathe under the armor. Heat and perspiration can get out, and fresh air can come in. In hot weather, you stay cool. In cold weather, you don’t freeze from frozen sweat after going in and out of cars and buildings. MDV 5.0 makes wearing body armor much more bearable.

"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." —Danny Gross (May 6, 2024)

"As someone who was doing Armed Security and now a LEO, I wanted to let anyone reading this that is was worth every penny. It was affordable, built with great materials, easy to wear, and best of all, my vest no longer smells!!!!!" —Customer (April 6, 2024)




Maxx-Dri Vest 5.0 provides greater comfort in both hot and cold weather, with these five improvements over v4.0 and all other versions:

1) Removable Side Straps. In v4.0, the side straps are permanently attached to the back of the vest and attach to the front with hook-and-loop material. This doesn’t work for everyone. Many users cut the strap off. They want to quickly throw the vest on, throw the body armor on top of that, and make all adjustments with the armor vest. With v5.0, the side straps attach to both front and back with hook-and-loop, and can be completely removed.

2) Greater Adjustability of Side Straps. Because the side straps are now fastened with hook-and-loop material on both ends, they can be length-adjusted on each end. This makes the vest fully adjustable. It provides more (or less) length to adjust for girth and enables you to vary that from one side to the other.

3) Less Movement, Better Stability. To better keep your armor in place, to keep it from shifting, we added non-slip grip material to the front as well as the back of MDV 5.0. On v4.0, this grip material is only on the back. Note that this all-around grip material is helpful if you want to remove the side straps.

4) Upgraded Material. The patented material is now 1.5mm thicker than on v4.0, expanding the layer of space between your body and your armor. In addition, the holes in the honeycomb weave are now larger, so more air gets through.

5) Extended Coverage. We’ve extended the length of the material along the torso and rib cage by one inch on each side. This gives you more coverage under your armor: More heat and moisture escaping. More air flow. More total ventilation.


We hear this a lot from customers who are incredulous at how well Maxx-Dri really works.


We make this promise: Try Maxx-Dri Vest 5.0 for 90 days and if you don’t love it, for any reason, we’ll pay the return shipping and issue your refund.


Made from a highly durable polymer with triple- reinforced stitching, Maxx-Dri Vest is nearly indestructible. It comes with a lifetime 100-percent money-back guarantee against breakdowns from manufacturing defects. It's been on the market for several years now and customers report that it still looks and works like new. You should have it for life.


Even though Maxx-Dri Vest may last a lifetime, you can buy more than one for convenience, or to give as gifts. We offer these discounts (enter the code at checkout):

3-4 vests, 10% off: MDV10
5-49 vests, 15% off: MDV15

Beat purchase I have ever made! I had 8 of my police co workers ordering them!


Works very well!!

Tammy Atchley
Pretty good

Seems like if your in motion on a bike or motorcycle you can feel the air movement and it’s great but to just be standing still its abilities are diminished

Robert O'Brien
Absolutely worth it!

I’m a horse mounted cop and summers can be brutal. This vest is a game changer. I feel a constant breeze between my body and my BP vest. No longer do I have the sticky clinging t shirt at the end of my shift. When I first received my 221B I thought, Did I really pay roughly $100 for this?!?”
After my first tour in it, I can honestly say it’s worth every penny!!

So glad you decided to get this for yourself, and that it's helping you!
