This men's RCAF heritage collection was designed in honour of the men and women who served — and who serve today — in the Royal Canadian Air Force. When the RCAF first started in 1924, they focused on civil air missions: forestry patrols, land surveys and anti-smuggling efforts. During WWII they peaked as one of the largest air forces in the world. Washed after printing to eliminate shrinkage. Made in Canada. SIZES FIT SMALL GO UP ONE SIZE.
