The WW2 US Army 1st Pattern HBT Jacket is an iconic World War II garment from the US Army. The HBT (Herringbone Twill) pattern refers to the fabric's specific weaving technique, which makes the jacket both strong and breathable. Here are some important details about this garment:

Features of the 1st Pattern HBT Jacket:
Pattern and Fabric: The jacket is made of Herringbone Twill (HBT), a diagonal weave structure that was typically used for workwear because of its durability. The pattern resembles a herringbone and was ideal for the hard work of soldiers in the field.

Color: The coat is usually greenish with a gray or olive green tint, a color that camouflaged well in nature and was suitable for World War II conditions.

• Design: The design of the first version was simple and practical, with large chest pockets, a button closure and a concise cut. It had no epaulettes (shoulder pads), which were later added in the later versions.

  Use: HBT jackets were worn primarily by American soldiers during World War II, especially those involved in logistics, recovery and other non-frontline functions. They were often worn during training camps and near the front line.

  History:The first version of HBT jackets was introduced in 1941 and was intended as a work uniform for soldiers. The 1st Pattern was replaced by the 2nd Pattern in 1942, which included some design changes.

• Longevity: The robust fabric and design also made the HBT jacket particularly suitable for long-term use in the harsh conditions of war tourism.
