MARMOT
An outdoor brand with roots in the “Marmot Club,” a mountaineering club founded in 1971 by two students at the University of California. Marmot revolutionized the industry by becoming the first outdoor apparel company to adopt GORE-TEX for its gear. Staying true to the free and creative philosophy of its founding, the brand continues to offer premium lifestyle wear around the world.

Lightweight, quick-drying, and reliable 100% polyester fabric
The fabric is made from 100% polyester. Using Marmot’s proprietary yarn, it delivers lightweight comfort and excellent moisture-wicking, quick-drying performance, making it comfortable for active movement.
It also features UPF50+ UV protection, antibacterial and deodorizing functions, and deodorant tape, making it reassuring even in sweaty seasons. This highly practical fabric is designed with waterside and outdoor use in mind.
A thoughtful design that protects the neck and lets you adjust the silhouette
The mock neck design provides solid coverage around the neck, where sun exposure can be a concern.
The front features the brand logo, while Marmot’s DOT M logo is placed at the back shoulder area, adding a subtle accent.
While offering sporty functionality, the overall look remains clean and streamlined.
Flatseam stitching is used throughout. In addition, the side seams are positioned at an angle to reduce direct friction, making it comfortable to wear even without an inner layer.
A colorful drawcord is placed at the hem, allowing you to adjust the fit and silhouette according to the scene.
Even in active situations, it is easy to change the impression of your styling.
A versatile active silhouette designed for easy movement
The silhouette has a clean balance suited to active use. Lightweight and easy to wear, it offers a stress-free feel while still looking great on its own.
Cinching the drawcord at the hem changes the look, allowing it to move naturally from sports to city wear. From waterside activities and mountain outings to festivals, this is a versatile piece that works across a wide range of settings.

The length is also well balanced and does not look sloppy. If you prefer a more relaxed fit for everyday wear, or a length that slightly reaches the hips, size XL would also be a good choice. |
