The differents materials used :

50% Nylon / 50% Cotton Twill

A twill weave is characterized by distinct, diagonal lines on the surface of the fabric. The inherent uneven texture and design of twill minimizes the appearance of stains and soils. Less interlacings allow the yarns to move with reduced restriction and consequently twill fabrics are more pliable than plain-weaves. The fewer interlacings also enable more tightly packed yarns with high thread counts. These durable high-count twills are wind, water and wrinkle resistant.

Proven to be long lasting and sturdy from decades of military use. Best for temperate weather.
50% Nylon / 50% Cotton Ripstop

Ripstop is a type of plain weave with coarse fibers ribbed at intervals designed to resist and reduce tears and abrasions (stops rips). It's lightweight and sturdy characteristics boast both wind and water resistance. Originally designed for parachutes, ripstop is the military clothing weave to demand when extreme durability is priority 1.

100% Cotton Ripstop

Lightweight, breathable, wind resistant, and durable. The ripstop reinforcement provides a checkered pattern to resist rips and tears. Ideal for warm to hot climates. May shrink more than the other materials. Ideal for firefighters.

Mandarin collar

More adapted for the use of body armor, they first appeared on the Close combat uniforms (2003) and are still present on current combat jackets (ACU, ACU-D and Multicam).
