Rayadillo

Rayadillo is a blue and white striped cotton fabric used to make the military uniforms worn by Spanish colonial soldiers before and during the Spanish–American War. The term rayadillo is Spanish, which translates to "striped material". In the mid-19th century, this material was referred to as being of hilo listado azure, or "blue striped thread". It was known as dril azul rayado or "blue striped drill" by the end of the century. Early examples of the fabric seemed to have had light blue stripes which were widely separated, while surviving examples of uniform jackets and trousers from the 1890s have thinner stripes of a darker blue, known during that period as mil rayas – literally, "a thousand stripes". Seen from a distance, rayadillo looked either very light blue or blue-gray.

The Revolutionary Army of the First Philippine Republic under Emilio Aguinaldo also employed the same fabric in their military uniforms during the later years of the Philippine Revolution and the Philippine–American War.

Military uniforms made out of the rayadillo material were of a number of patterns:

The guerrera, or campaign jacket worn with the rayadillo uniform was made of deep blue flannel and had two breast pockets with flaps. It was fastened by a single row of seven metal buttons. The jacket was patterned on the tunic officially prescribed for general wear by the infantry of the Spanish Peninsular Army on August 18, 1886. The guerrera was worn by Spanish troops stationed in the Philippines, Cuba and Puerto Rico. The Philippine-issue rayadillo patterned guerrera was distinguishable from those issued in Cuba and Puerto Rico by a standing collar and concealed button fly front. A single hook and eye is found at the bottom of the collar opening. This uniform was issued in 1891 until 1898.
