The pea coats adopted in the 1910s were comprised of a waist-length type and a knee-length type. Both types use high-density thick melton wool and have anchor buttons engraved with 13 stars representing the seal of the United States. However, there are differences in their details. The waist-length type has hand warmer pockets on both sides, and the lining is made of rayon cotton. The knee-length type has hand warmer pockets and flap pockets underneath, and the lining was wool. While both were adopted in the 1910s and the exact year of their adoption is not clear, the knee-length type undoubtedly provides greater protection from the cold.
