The French really understand parched, roasting climates. From 200 years of walking around North Africa, they figured out what to wear for brain-boiling heat.
If you’re a regular reader of Lean, Solid Dogs, you already know that I love short shorts. And my favorites are surplus French Army shorts. Cheap, durable, and comfortable, they would be 100% perfect if not for the tragic European aversion to back pockets.
But my French cousins absolutely aced one other piece of hot weather gear: the GAO shirt. Think of it as an optimized tank top. Its most distinctive feature is that it doesn’t have sides, just straps that hold the front and back together while ventilating your body. For even more ventilation, there’s a deep V-neck that leaves about half your chest exposed to the air. Only the shoulders get extra coverage to protect them from the sun and the chafing of pack straps or other loads. And the designers even compensated for the lack of back pockets on their shorts but putting a sort of dump pouch across the small of the back, like some cycling jerseys have.
The GAO shirt’s origins are somewhat mysterious and people are unsure where the name comes from. It might be named after the Gao region of Niger, or it could be an acronym for “Operational Support Group” (Groupe d’Appui Opérationnel). What we do know is that it appeared in 1983 in Chad, when the French Army helped repel a Libyan invasion.
To my surprise, I’ve never seen a GAO shirt on anyone else in the United States. Peerless for hot, dry weather, they deserve to be better known. I first saw them years ago in Claire Denis’ film Beau travail and instantly saw how comfortable they would be.
French surplus GAO shirts are cheap but very difficult to buy from within the US for some reason, even in the age of Ebay and FedEx. However, they are easy to make. If you get hold a French specimen to copy, a sewing machine, and some 33% polyester ripstop fabric, you’re in business.
