Massif US Army Combat Shirt Gen II (FR), Color Multicam

This is not just a UBACS. This is a standard that has been used by the US Army for years and proven in real conditions.
Massif is an official contract manufacturer. And this shirt is not made to “look tactical”, but to perform under load, in heat, and with gear.

Why this UBACS is actually great:

You put it on — and immediately feel the difference. The torso works like base layer: wicks moisture, breathes, and does not overheat even when fully geared. Under a plate carrier this is critical: no unnecessary seams, no chafing, maximum comfort even during prolonged wear.

Real flame resistance, not marketing

This is not just fabric with additives.

Full Flame Resistant (FR) technology:

• meets ASTM D 6413-99 standard
• does not melt
• does not support combustion
• does not drip when exposed to flame

This is the level used by vehicle crews and those operating in the most demanding conditions.

Balance of comfort and durability

The torso is lightweight, elastic, and breathable. The sleeves are as much as possible durable.

Reinforced elbow areas with SuperFabric® provide protection against abrasion during active movement and work. This is not about “wearing carefully”. This is about “wearing it and not worrying”.

Gen II — not just an update

The second generation received real improvements:

• zip collar — adjustable ventilation and neck protection
• improved fit — better ergonomics without restricting movement
• extended camouflage zones — more protection where it matters

Details that matter in use:

• sleeve pockets with YKK zippers
• Velcro panels for patches, flags, and identification
• slots for pens / markers
• flat seams — no chafing even under load

Materials

Massif proprietary blend:
60% Cotton / 24% Rayon / 8% Polyester / 8% Spandex

The composition may slightly vary depending on the garment zones to ensure optimal balance between breathability, elasticity, and durability.

Where it is used:

• field conditions
• training / shooting range
• airsoft
• active outdoor
• work in gear in hot climates

This is the kind of gear you stop thinking about — because it simply works with you.

Massif US Army Combat Shirt Gen II — is a standard of comfort and protection proven over time. If you need a truly functional UBACS, not just the look — this is one of the best options.
