About "Mac in a Sac"

Mac in a Sac is an outdoor apparel brand founded in Belfast, Northern Ireland in 1987.

With "Packable", "Colourful", and "All Purpose" as its brand core, it is characterized by its functionality that can be carried anywhere and its wide range of color variations.

Under the concept of "a jacket that fits in a bag," which is also the origin of the brand name, it offers packable wear that combines lightness, waterproofing, and portability. All models are equipped with a function to be compactly stored in a dedicated pouch, making them suitable for a wide range of scenes from outdoor activities to daily life. In 2004, the brand became independent as Mac in a Sac. It is now available in over 20 countries and is supported by outdoor enthusiasts and travelers.

In April 2026, Tsuda & Co., Ltd. began operating the brand as the official Japanese distributor, launching new developments for the Japanese market.
