Combat Shirts

You don’t buy a combat shirt because it’s “part of the uniform”, but because standard clothing simply doesn’t work under a plate carrier. When standard tops are worn under plate carriers, they can quickly lead to heat build-up, chafing seams and restricted movement.

Go straight to the relevant information:
• Why standard shirts don’t work well under plate carriers
• Which combat shirt suits your playing style?
• Fit and ergonomics
• Colours and camouflage patterns: when should you choose which?
• Frequently asked questions

The difference between budget and premium combat shirts lies primarily in ventilation zones, fabric construction and the positioning of seams under load. It’s not just about the material, but how the shirt works in conjunction with your entire loadout. Cheaper models look fine at first glance, but often lack strategic ventilation zones, clever seam placement and durable fabrics that can withstand intensive use. Brands such as Clawgear and Helikon-Tex develop their shirts specifically with this in mind, focusing on prolonged wear under weight and movement. High-quality combat shirts maintain ventilation, freedom of movement and comfort significantly better during prolonged gameplay whilst wearing gear.

During longer gaming sessions, the difference in temperature regulation and comfort becomes immediately apparent. Fewer distractions, less heat build-up and greater focus on your game or mission. This is particularly noticeable among players who switch from standard clothing to a dedicated combat shirt; the difference in comfort and focus is immediately apparent.

Why standard shirts don’t work well under plate carriers

Many standard outdoor shirts and cotton tops are simply not designed for prolonged wear under plate carriers or chest rigs. Particularly during intense gameplay, problems such as heat build-up, chafing seams and restricted freedom of movement can quickly arise, as traditional clothing designs do not take sufficient account of the strain caused by tactical gear.

With standard shirts, the shoulder seams often sit directly beneath the load-bearing sections of a plate carrier. During longer skirmishes, this causes additional pressure points and irritation around the shoulders and collarbone. This difference is particularly noticeable with heavier loadouts or when carrying magazines, radios and hydration packs for extended periods.

Cotton shirts also retain significantly more moisture during active gameplay. As temperature and exertion increase, the fabric becomes saturated with sweat, reducing breathability and making the shirt feel heavier. In CQB and hot outdoor conditions, this leads to overheating more quickly and reduced comfort.

Limited stretch is also a common problem with standard outerwear. During sprints, weapon transitions and kneeling movements, tension builds up more quickly around the shoulders, chest and arms, restricting freedom of movement. Tactical combat shirts therefore often feature elasticated panels and ergonomic cuts that move more freely under strain.

Furthermore, the seams on standard shirts are not usually designed to withstand prolonged friction under tactical gear. As a result, cheaper constructions are more likely to cause chafing under plate carriers, slings and chest rigs. Premium combat shirts, on the other hand, use flatlock seams, breathable torso fabrics and strategically placed stitching to significantly reduce pressure points and heat build-up.

Which combat shirt suits your playing style?

Not every combat shirt is designed for the same conditions. Playing style, temperature and type of loadout ultimately determine which features of a combat shirt are truly relevant.

• CQB, fast-paced indoor gameplay
In CQB, confined spaces and high-intensity movement lead to a faster build-up of heat, making ventilation and stretch fabrics all the more important. A breathable torso prevents overheating in confined spaces, whilst minimal bulk ensures quick and fluid movements.

• Outdoor skirmishes and day events
Outdoor gameplay requires, above all, durable sleeves, moisture-wicking properties and protection against prolonged contact with the terrain and gear. Think of shirts with durable ripstop sleeves, a breathable torso and space for elbow pads. Invader Gear often offers a good balance between price and functionality in this regard.

• Milsim events, extended operations
During extended milsim events, shoulder strain, ventilation and practical storage options become significantly more important. Combat shirts with shoulder padding reduce pressure points caused by your plate carrier. Extra storage pockets on the sleeves are not a luxury but a practical feature for maps or small tools.

• Professional use and training
In professional applications, no-melt/no-drip materials and IR-reducing properties are becoming increasingly important due to heat stress and use with night-vision equipment. Clawgear and Helikon-Tex clearly stand out in this regard thanks to their high-quality construction and choice of materials.

What you really need to look out for in a combat shirt:

• How effectively does the torso dissipate heat and sweat during exercise?
• Whether the sleeves can withstand heavy use and contact with gear and terrain
• Whether the shirt has room for elbow pads
• Whether the Velcro panels are positioned practically and do not cause irritation under load

Combat shirts vary greatly in terms of breathability, fit, durability and functionality under stress.

Fit and ergonomics

The fit plays a major role in determining how comfortable a combat shirt is when worn under tactical gear. A poorly fitting torso is more likely to chafe under a plate carrier, whilst sleeves that are too loose can get in the way during rapid movements. An incorrect fit is more likely to cause chafing, heat build-up and restricted freedom of movement during active gameplay.

Athletic-fit styles are form-fitting and move with your body. Clawgear specialises in athletic-fit designs that fit snugly under plate carriers and chest rigs.

Regular-fit styles, such as those from Invader Gear, offer a little more room and are more comfortable when you’re wearing multiple layers or playing for long periods.

Helikon-Tex strikes a balance between the two, combining freedom of movement with comfort, making it a popular choice for players looking for versatility.

Colours and camouflage patterns: when should you choose which?

The choice of colour has a direct impact on the effectiveness of camouflage in different play environments. In outdoor settings, black often creates an unnatural break in the silhouette, which actually reduces the effectiveness of camouflage.

Camouflage patterns such as Multicam or Flecktarn are significantly more effective in outdoor environments. Ranger Green works well as an all-round colour, particularly in mixed terrain. For CQB, camouflage is less important, but darker shades can still help you remain less visible in shaded areas.

Our advice:
Match your colour to your playing environment
Pair with matching combat trousers
Use patches that don’t clash with your outfit

In this category, you’ll find a wide range of colours and patterns to suit different playing styles and environments.

Frequently Asked Questions

What is the difference between a combat shirt and a normal shirt?
A combat shirt combines a breathable torso with hard-wearing sleeves and is specifically designed for use under gear such as plate carriers.

What do you wear under a combat shirt?
In most cases, nothing extra. The shirt is designed to be worn directly against the skin, ensuring optimal ventilation and moisture management under your gear.

Are combat shirts suitable for hot days?
Yes, thanks in particular to the moisture-wicking fabric, they remain comfortable even during intense gameplay.

What does ‘No-Melt, No-Drip’ mean, and do I need it?
‘No-Melt, No-Drip’ is a specific material property (often a cotton/nylon blend such as NYCO) that prevents fabric from melting or dripping when exposed to extreme heat or open flames. In professional applications and milsim gameplay involving pyrotechnics, no-melt/no-drip materials significantly increase safety. Whereas standard polyester melts directly onto the skin when exposed to heat, resulting in severe burns, ‘No-Melt’ material will simply char. This significantly increases your personal safety in the field.

Do I need elbow pads?
We strongly recommend them for outdoor and milsim activities. Many shirts have built-in compartments for this purpose.

Which brands are the best?
Clawgear and Helikon-Tex offer premium quality, whilst Invader Gear is a strong choice in the mid-range.

Can I attach patches to a combat shirt?
Yes, most models have Velcro panels on the sleeves for patches and identification.

Pair your combat shirt with matching combat trousers, a functional combat jacket, or complete your outfit with airsoft patches for identification and personalisation.

With the right combat shirts, you can choose a loadout that suits your playing style, so you’re less distracted and can perform at your best during every skirmish.
