Story & heritage
The Spec 73 tee points directly at the brand’s origin year: Billabong was founded in 1973 on Australia’s Gold Coast. That makes the shirt a compact brand-history piece as much as a basic tee.
The official product page presents it around core logo graphics and a classic OG fit, keeping the design close to surf-shop essentials.
Materials & craft
Official specs list a Premium 24/1, 180g T-shirt with soft-hand screen print, OG fit, a left side-seam flag label and the Spec 73 collection name.
How to choose & style
This is the tee to layer over trunks or under an open overshirt. Fog Gray keeps the logo readable without shouting, so it works with faded denim, navy shorts or black boardshorts.
