Meet Ultradyne: Alpaka’s Strongest and Lightest Performance Fabric
Materials shape the way we carry.
For years, everyday carry has balanced three competing priorities: weight, durability, and weather protection. Improve one and you often sacrifice another. Lightweight bags can wear out faster. Heavy-duty fabrics add unnecessary bulk. Weatherproof materials sometimes feel stiff or overbuilt.
With Ultradyne, Alpaka set out to rethink that equation.
Now available at Urban Traveller & Co, the new Ultradyne Collection brings together four of Alpaka’s most popular slings: the Flight Sling 1L, Flight Sling 2L, Metro Sling V2, and Metro Sling Max, all upgraded with Alpaka’s newest high-performance fabric.

Why Ultradyne Matters
Ultradyne isn’t simply another premium textile.
Built using ultra-high-performance fibers, it offers an exceptional strength-to-weight ratio that allows Alpaka to create bags that are remarkably light while remaining incredibly resilient.
Compared with conventional carry materials, Ultradyne provides greater resistance to abrasion and daily wear, helping your bag maintain its appearance through years of commuting, travel, and everyday use.
Its tightly engineered construction also delivers dependable all-weather performance, giving you added confidence when sudden rain or unpredictable conditions become part of your journey.
The result is simple: less weight on your shoulder, greater confidence in your gear.
Flight Sling: Built for Travel
The Flight Sling 1L and Flight Sling 2L are designed for travellers who want quick access without carrying more than necessary.
Whether you’re reaching for your passport during immigration, your boarding pass at the gate, or your phone during a morning commute, the Flight Sling keeps your essentials organised, protected, and always within easy reach.
Available in two sizes, it adapts whether you’re carrying only the basics or packing a little extra for longer days away from home.

Metro Sling: Everyday Carry Refined
If your everyday carry includes more than just the essentials, the Metro Sling V2 and Metro Sling Max offer additional capacity without compromising Alpaka’s streamlined aesthetic.
Perfect for tablets, notebooks, chargers, cameras, and work essentials, the Metro Sling balances organisation, comfort, and accessibility throughout your day.
Combined with Ultradyne, it becomes even more compelling: lighter to carry, more durable over time, and ready for whatever your schedule throws at it.
One Collection. Four Ways to Carry.
Every person carries differently.
Some travel light. Others bring their office everywhere. Some spend more time in airports than meeting rooms.
The Ultradyne Collection doesn’t ask you to change how you carry. It simply gives you a stronger, lighter, and more capable foundation to carry with confidence.
The Flight Sling 1L, Flight Sling 2L, Metro Sling V2, and Metro Sling Max in Ultradyne are now available at Urban Traveller & Co stores and online.
Experience Alpaka’s most advanced performance fabric and discover why the future of everyday carry isn’t about carrying more. It’s about carrying better.
