Propper® Long Sleeve OCP Combat Shirt (F5817)

This isn’t a fashion piece—it’s built for people actually doing the work.

The Propper® OCP Combat Shirt (F5817) is engineered specifically for wear under body armor and load-bearing gear, where heat, sweat, and restricted movement become real problems fast. This shirt fixes that.

• Torso: 100% moisture-wicking polyester with antimicrobial finish
  → Keeps you dry, cuts down odor, and doesn’t turn into a swamp under armor
• Sleeves & Collar: 50/50 nylon-cotton (NYCO)
  → Matches your OCP uniform and holds up to real abuse
• Lightweight knit body
  → Breathable where you need it most, without sacrificing durability

Designed for Movement

• Raglan sleeves + underarm gussets
  → Full range of motion—no binding when reaching, lifting, or shouldering gear
• Flatlock seams
  → Reduces chafing during long wear
• Stand collar with ¼ zip + mesh lining
  → Prevents neck irritation from armor and straps

Functional Where It Counts

• Two zippered bicep pockets
  → Secure storage with loop panels for patches/insignia
• Adjustable hook & loop cuffs
  → Lock in fit depending on conditions
• Reinforced elbow patches
  → Because you will hit the ground eventually

Why This Shirt Exists

When you’re wearing a plate carrier or armor system all day, a standard uniform top becomes hot, restrictive, and miserable. This shirt is purpose-built to solve that—keeping your core cool while maintaining a uniform, professional OCP appearance where it’s visible.

Bottom Line

The Propper® Combat Shirt is for serious use—not casual wear.
If you’re training, working, or operating in gear for extended periods, this is one of those items that makes a noticeable difference fast.
