A reliable jacket is critical for security personnel who are working in cold environments to keep warm and focused while working shifts.

Here are five effective outerwear options, including the M65 Army Field Jacket, that offer protection and performance for winter patrols and outdoor security work.

1. M65 Field Coat — The Classic All-Season Duty Jacket

The Propper® M65 Field Jacket combines military heritage with practical, duty-driven design. Its proven construction makes it ideal for harsh conditions and extended outdoor assignments.

  • Features an 8.5 oz 50/50 nylon-cotton sateen shell with DWR treatment for wind and water resistance.
  • Removable quilted liner and fully lined shell for adaptability across temperature ranges.
  • Four secure snap-closure pockets and a packable hood stored in the collar.
  • Field-proven design trusted by military and security professionals for decades.
Best For

Overnight patrols, perimeter security, facility guards, or any duty requiring reliable weather protection and gear storage.

Recommendation: Stock both standard and long sizes to support varied body types and layering requirements.

2. Waterproof Duty Jacket — Essential for Wet and Harsh Weather

The Waterproof Duty Jacket is engineered to deliver durability and weather protection without restricting mobility during active duty assignments.

  • Removable quilted polyester liner for adaptability in changing weather conditions.
  • Side zips allow rapid access to duty belts and equipment without removing the jacket.
  • Integrated epaulets and mic/camera loop support professional utility needs.

3. BA Softshell Jacket — Mobility for Active Patrol

The BA Softshell jackets balances protection and mobility for security teams that require agility, including campus safety, foot patrols, and close-protection roles.

  • Lightweight, flexible fabric allows for high mobility during rapid response or extended patrols.
Best For

Quick-response teams, bicycle units, campus security, and urban patrols requiring agility and adaptability.

4. Insulated Parka or Shell Jacket — Maximum Warmth for Severe Cold or Long Shifts

When temperatures drop and guards are exposed for prolonged periods during long overnight posts, the Gen II Parka becomes essential.

  • Thick insulation helps retain heat even when standing idle or during minimal activity.
  • A water- and wind-resistant outer shell shields against snow, sleet, and strong wind chill.
  • Ample pocket space and compatibility with duty belts/packs make these jackets practical for extended duty duration.

Winter guard duty, remote site security, overnight perimeter patrols, static outdoor posts, and assignments requiring maximum warmth and long-shift durability.

5. Packable Waterproof Jacket — Lightweight Protection for Transitional and Wet Conditions

The Packable Waterproof Jacket is constructed from lightweight ripstop material and designed to block moisture and dirt while providing reliable protection from rain and wind.

  • Fitted hood with elastic adjustment enhances visibility.
  • Fully sealed seams and DWR finish protect against rain, drizzle, and wet conditions.
  • Chest pocket offers convenient storage for small essentials.
Best For

Personnel patrolling parking areas, managing event traffic, providing event security, operating on bikes or mobile units, and working in mixed indoor/outdoor environments where lightweight, deployable protection is needed.

Inventory & Procurement Recommendations

  • Maintain at least two jacket types per patrol team (e.g., M65 + Softshell or Waterproof Jacket) to cover varied duty conditions.
  • Stock a full size range (S–XXL or extended sizing) to support layering and diverse body types.
  • Rotate inventory seasonally, deploying heavier jackets in winter and lighter options during transitional months.
  • Invest in maintenance supplies such as replacement liners, waterproofing treatments, and high-visibility accessories to extend service life.

Final Take: Gear Up with the Right Jacket for the Mission

No one jacket is best suited for every job in security. The right type of outerwear will depend on the needs of the mission, including the weather, how much movement is required, and the working environment of an individual's job. By developing a complete outerwear collection, including both heavy-duty M65 Field Jackets and lightweight softshell jackets, individuals will be better equipped to handle variable winter conditions, rainy weather, night shifts, immediate responses, and much more.
