Built for one-and-a-half bag travel, the Muir III offers unparalleled convenience and efficiency. Its huge U-Zip opening allows for easy packing and unpacking, giving you quick access to all your essentials. Multiple access options, including side and top zippers, ensure that you can retrieve your belongings without any hassle, no matter where you are.

The front quick-access pocket is perfect for items you need to grab in a hurry, while the internal mesh pockets help keep smaller items in check.

The Muir III is constructed using X-Pac X11 fabric, a cutting-edge material known for its exceptional durability, lightweight properties, and weather resistance. This advanced fabric features a unique multi-layer design, combining a rugged nylon face with a waterproof laminate and a polyester X-PLY® grid for added strength and stability. The result is a bag that can withstand the rigors of travel and adventure, protecting your gear from the elements while maintaining a sleek and stylish appearance.

The removable sling is a standout feature, providing additional internal storage when you need it or serving as a sleek, standalone bag for lightweight adventures. Whether heading out for a quick hike or exploring a new city, the sling adapts to your needs, offering flexibility and convenience.

The bag also features premium Austrialpin COBRA Frames, renowned for their unparalleled strength and reliability. These high-performance buckles provide secure closure and easy adjustability, ensuring that your belongings are always safe and easily accessible.

Adding a touch of heritage and a nod to our past collaborations, the Trakke x Carryology Muir III incorporates Lochcarron of Scotland tartan. Woven by one of Scotland's oldest and most respected mills, this authentic tartan not only enhances the bag's aesthetic appeal but also pays homage to traditional craftsmanship.

    Well thought out crossover pack

    A well thought out pack for travel or EDC use. Quite rigid and structured and like a stiff version of the old Arc’teryx Sebring. I returned it as it didn’t offer much over my Storr 20 and 35 but if you don’t have one of these get the Muir III.

    Bad A$$ bag

    This is my first Trakke bag and i’m so impressed with the feel, materials, organization that I am trying to determine what my next purchase will be. I’m so happy I got it!

    Absolutely beautiful! A pack that has been so over-thought it should by rights be terrible - but it is an complete triumph. This should be your new unicorn. Time will tell of course, but for now, I’m in love!
