⚙️ Sizing Tips

- The second number is your chest or waist in cm.
- Military gear is usually cut roomy for layering and movement.
- If you’re between sizes, go down for a closer fit or up for layering.
- Example: 5'11" tall with 40" chest → 180/104 (Large).
Genuine Dutch Army "Koala" Thermal Top – Long Sleeve Base Layer (Grade A Surplus)
Product Overview
The Dutch Army "Koala" Top is a legendary piece of cold-weather kit, widely regarded as one of the warmest military base layers ever issued. Named for its thick, soft, "fleece-like" interior pile that traps body heat with incredible efficiency, this long-sleeve thermal is designed for static guard duties and extreme low-temperature operations. Sourced as Grade A Surplus, these tops offer professional-grade thermal protection at a fraction of the cost of commercial outdoor gear.
Key Features & Functional Benefits
-
Superior Thermal Retention: The "Koala" pile lining creates a thick loft of insulated air against the skin, providing immediate warmth in sub-zero conditions.
-
Moisture Management: Despite its thickness, the synthetic blend is designed to wick sweat away from the body, keeping you dry and preventing "cold-soak" during activity.
-
Extended Wrist Cuffs: Often features integrated thumb loops or extra-long cuffs to ensure the sleeves stay in place and provide additional warmth for the pulse points at the wrists.
-
Zip-Neck Collar: The high-mandarin collar features a 1/4 zip, allowing you to seal in heat or vent excess steam when your activity level increases.
-
Military Durability: Built to withstand the rigors of service, with reinforced stitching and a rugged outer face that resists pilling under heavy outer layers.
-
Grade A Condition: These are genuine surplus items in excellent used condition. They are clean, fully functional, and have plenty of life left in the thermal pile.
Understanding NATO Sizing
The Dutch Army uses an 8-digit NATO sizing system for a precision fit. The numbers are broken down into two sets:
-
First 4 Digits (Height): Represents the height range in centimeters.
-
Example: 7080 = Designed for a person between 170cm and 180cm tall.
-
-
Last 4 Digits (Chest): Represents the chest circumference range in centimeters.
-
Example: 9505 = Designed for a person with a 95cm to 105cm chest.
-
Quick Tip: If you fall between sizes, we recommend sizing up if you prefer a looser fit, or staying true to your range for the "second-skin" fit required for maximum thermal efficiency.
