Rick Hemmerling and Joe Boldan founded ExOfficio in Seattle in 1986. Their first project was to design a shirt for fly fishermen. They took a simple Brook Brothers button-down style men’s shirt, fabricated it in a quick-dry nylon and added cargo style chest pockets, a flip up sun protective collar, and back placket ventilation. That shirt is still a bestseller known as the Airstrip, now with UV sun protection. The company created the first nylon pants with zip-off legs called the Ziwa Convertible Pant, now made with Bugs Away insect repellent. Later they launched Give-n-Go travel underwear made with quick-drying, diamond-weave nylon. Just wash it in the sink, wring it out in a towel, and let it hang-dry overnight.
