As a police officer committed to wearing body armor, he was determined to find a solution to soaking in sweat, smelling, and being distracted by skin irritations and even infections. He figured out that, 1) his base-layer shirt needed to be breathable, not just moisture wicking, and 2) to make it breathable, he needed a layer of space between his shirt and body armor that allowed body heat and moisture to escape and air to flow in. So he created a lightweight vest made out of a special mesh material—the “\u003ci data-mce-fragment=\"1\"\u003eMaxx-Dri\u003c\/i\u003e” material—to go between his body and his armor.

INTERNATIONAL SHIPPING
First Class International Package is the most affordable shipping option but please be aware that it may take between 4 - 10 weeks for delivery depending on your location.
There may be delays due to Increased volume and carrier’s reduced capabilities to handle packages related to COVID-19. Please allow more time in consideration of current situation.
All prices on our site are in US dollars. Your credit card company will bill you with your local currency at the current exchange rate.
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.
If you have any shipping questions regarding your order, please contact us: Support@221btactical.com

WHY YOU NEED THIS
Ever take your backpack off and find the back of your shirt completely soaked with sweat? This leaves you with a big, embarrassing wet spot on your back...awful if you happen to be heading to class, work or an event.
Imagine being able to walk, run, hike, ride your bicycle/motorcycle or skateboard with your backpack on without having to worry about a huge, embarrassing wet spot on your back when you take your backpack off...
The Maxx-Dri Backpack Airflow Spacer helps Maxximize the airflow between your backpack and your back which allows for a drier, less sweaty shirt while you wear your backpack, and most importantly, when you take your backpack off.
The Maxx-Dri Backpack Airflow Spacer was spawned from the success of our Maxx-Dri Vest for body armor ventilation. The Maxx-Dri Vest is worn by tens of thousands of Police Officers and Military Operatives world wide to provide ventilation and cooling beneath their bullet resistant vests.
FEATURES:
3D AIR FLOW TECHNOLOGY that will allow fresh air to flow between your back and your backpack so your sweat can evaporate and your shirt can get DRY.
Our proprietary Maxx-Dri mesh does not absorb moisture like the many other commercial mesh materials already sewn into your backpack. Those meshes, in reality, actually soak-up sweat and make you feel wet and uncomfortable.
Does not hold any moisture. You can wear it in the rain or snow. It helps keep your weather-soaked backpack off your body. You'll be drier, more comfortable and cleaner.
Reflective Strap hooks around your backpack to make you more visible...especially at night time. This is an extra, potentially life saving feature we added for your safety.
SIZE CHART:
SMALL: 12" WIDTH x 15" HEIGHT (Best fit for backpack sizes : 11-14" WIDTH x 12"-15" HEIGHT)
MEDIUM: 12" WIDTH x 18" HEIGHT (Best fit for backpack sizes : 11-14" WIDTH x 16"-18" HEIGHT)
LARGE: 12" WIDTH x 21" HEIGHT (Best fit for backpack sizes : 11-16" WIDTH x 19"-23" HEIGHT)
* Simply measure the back side of your backpack for the most accurate fit based on the above sizing recommendations.
It helps you sweat less, it doesn't always happen. Reduces humidity by 25 to 30%. You feel more comfortable. The material does not smell or cause irritation. Helps with luggage pressure.
Thanks for your review. In addition to what you wrote, its main purpose is to facilitate evaporation of sweat which helps with drying-out people's shirts, mitigate having to wash one's carrier-vest frequently, reduce skin maladies, help with luggage pressure (as you wrote), etc. Hope we can earn your 5 star review in the future. - Brad @ 221B

The backpack accessory to rule them all
Wow. This spacer is prime time, the real deal. When I bought my Yeti Panga 28, I had an uh oh moment when I realized how unbreathable the backpack is. Enter 221B. After an easy install I ended up going for 2. I use both the size large and size medium. When you use two, the material seems itchier on the back. The airflow seems reduced by maybe 15% as well. That being said, I couldn't care less, as the padding improvement from 2 spacers is 10 out of 10. Specifically when carrying a fully loaded bag - the load is so much more pleasant with 2 spacers. I'm just spitballing here, but if you're not carrying over 8 or 10 pounds, I don't think you'd have a need for 2 spacers. Couldn't recommend this product enough.
