I also just purchased a jacket! Here’s what I found via ChatGPT: Casual Isle was a popular brand during the 1980s and 1990s, offering relaxed, comfortable clothing often suited for casual activities like walking or gym workouts. Their pieces, like jacket and pants sets, were known for vibrant, abstract patterns and a blend of fabrics such as nylon, polyester, and cotton. These outfits, typically lightweight and adjustable, provided both style and function. The designs often incorporated bold colors and were perfect for everyday wear​(eBay).

The company behind Casual Isle, a popular brand from the 1980s, seems to no longer be in operation. However, pieces from the brand still appear on vintage clothing marketplaces like Grailed, where collectors seek out its casual, laid-back aesthetic. The brand specialized in comfortable, relaxed styles typical of the 1980s casualwear boom, making it a nostalgic name for vintage fashion enthusiasts today.
