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.

Wears like a shirt yet protects you like a coat. Thermal, wind-blocking, and breathable. Comfortable even when you come in out of the cold.

"I don’t know how you did it! I wore the shirt around the house without getting overheated after it arrived, so was admittedly skeptical of how warm the Stage 3 would be in the cold on duty….It was 23 degrees with a light breeze when I headed to the range wearing this base layer under a short sleeve polo and external vest carrier. To my amazement I was completely comfortable for the entire range day without compromised mobility". —Ryan A. (Nov. 15, 2020)


The Freedom to Work and Play Outdoors

Police Duty. Construction Work. Hunting. Hiking. Biking. Golf. Any Outdoor Activity!  Equinoxx Stage 3 Ultra-Thermal let’s you work or play outdoors in cold, windy weather, yet stay flexible and enjoy full range of motion. It gives you freedom! And freedom of motion promotes safety, as well as comfort and convenience.

"All my coworkers had on the bulky carhartt jackets with hoodies underneath and whatever else. They couldn’t believe I was out in that climate with no jacket....This is perfect for construction and doesn’t restrict movement at all."  
—Mario Jimenez (Jan. 21, 2022)

"Right now in Chicago it’s 10 degrees with high winds, everyone at my agency is wearing a coat. All i’m wearing is my thermal with a vest carrier, and I don’t feel the cold coming through at all." —Samuel B. (Jan. 5, 2022)

Innovative Design & Materials 

The "Grid" design structure of the base layer’s fleece inner liner is the latest technology to reduce fabric weight while increasing warmth and compress-ability. This form of construction enhances both wicking efficiency and breath-ability by generating channels of targeted touch points that absorb and diffuse moisture vapor for faster evaporation.

Thermal material covers your shoulders, sleeves and upper chest. Tight wrist cuffs ensure that cold air doesn’t run up your arms. The mock-neck design protects your neck. But you need to breath at the core, the torso. So the core of Equinoxx is made with moisture-wicking, breathable material to keep you dry. To stay warm at the core, you might wear a vest over Equinoxx. If you’re police offer, you might wear body armor.

"I work in WI so I need to be warm in the winter. I do not like to wear a coat, as I personally feel it is hard to get to my gear. This is PERFECT! I stay warm but I am not sweating under my vest. LOVE IT!!" —Lina E. (Feb. 9, 2019)

Please have it white

I wish this came is white also since the department I work for only allows white colored under shirt.

Perhaps next year we will add other colors. For now, only Black is offered. Thank you.

Excellent equipment

This is an excellent piece of equipment, well made and fitting exactly to size. It won’t keep you warm without a coat on a cold day, so I’m skeptical of that claim, but it does hold some warmth. Regardless, in all respects, it is a go-to piece of tactical equipment.

Great product

Wearing it today starting to be cool here great arm protection without worrying about dexterity with my equipment!

The hubby and I are impressed!

So for references, here you go:
Hubby (Active L.E.O.)-M, 6'1", 250pds, got XL
Me (Armed Security)- F, 5'4", 179pds, got M

We have been wearing them for the passed couple of days, in weather of 55° and lower @ 15+ MPH winds, and we are so pleased with its performance. The ordering was easy and simple and it came in right on time. We had an unexpected cold front come in and we were warm and comfortable, yet mobile to where we didn't feel restricted to our gear. We highly recommend it and appreciate the one who made it. Finally! Someone who gets it and created a product that we now have a confidence in, instead of blowing money on finding the "right" fall/winter attire so we can stay professional but comfortable. A wonderful investment that you won't regret.

Thank you for your thoughtful and complimentary review! We are so pleased that you're pleased! - Brad @ 221B Tactical

Warmth without the bulk

Wearing the Stage 3 during the long cold winter months will mean you will be warm without having a bulky jacket or even the bulk of extra layers. This will keep you warm while having the appearance of a traditional mock turtleneck. I look forward to wearing it in the winter while being comfortable in the face of old man winter. If you are on the fence, buy it.
