Context

There are over 300,000 walking tour guides globally, each offering different experiences and having different needs.

Walking tours are often in high-density urban areas with higher risks of pickpocketing. Tours last anywhere between 2–8 hours — demanding a bag that can handle a full workday on foot.

Guides need to carry essentials, remain identifiable to their group, switch quickly between front-carry and back-carry, and keep valuable items secure — all while looking the part.

Research

"I'd rather have a bag that can carry all the stuff I might need during the day. Smaller messenger bags barely fit enough items."

"Comfort is key."

"I hate that it's designed for only my left shoulder."

The Problem

Walking tour guides need a bag that securely transitions between back and front-carry, comfortably fits a full workday of essentials, and is made from sustainable materials — without sacrificing their professional appearance.

Constraints

Security

  • Easy to switch from back to front carry
  • Hard-to-access pockets for valuables

Comfort

  • Ambidextrous shoulder strap
  • Lightweight construction
  • Back padding

Functionality

  • Space for wet gear
  • Identifiable in a crowd
  • Expandable to fit flexible carry needs
  • Easy access pockets for low-value items
  • Waterproof

Sustainability

  • Prioritise upcycled & second-use materials
  • Durable construction for long life

Sketch Models

Sketch model process 3
  • Water bottle holder test: sleeve too shallow; angle makes it hard to insert
  • Form too unstructured; no cohesion
Sketch model process 2
  • Nice form
  • Bisection reminiscent of a flag
Sketch model process 1
  • Bag sits awkwardly on body
  • Straps need to be moved up to the top
  • Needs padding to add structure
  • Make taller to fit binder/iPad

Making the Bag

The bag was pattern-made and sewn from upcycled materials. Each seam and pocket placement was iterated through physical prototyping.

Key Features

+
Security A click–flip–zip entry adds friction to the main compartment, deterring quick access, while a hidden, body-facing pocket keeps valuables fully out of reach. The bag can also be rotated to the front in crowded or high-risk environments.

+
Comfort An ambidextrous strap allows for easy wear on either shoulder, while a padded back panel adds structure and cushioning for all-day comfort.

Sustainability All primary materials are sourced from discarded textiles. The body is made from an upcycled sail, paired with marine vinyl from industrial offcuts. Rather than becoming waste, these materials are given a second life—without compromising performance: durable and highly water-resistant.

Learning
Takeaways

01

Prioritizing physical prototyping kept the project grounded in what I could actually make, letting me focus on craft and obsess over details.

02

Physical iteration exposed ergonomic issues that wouldn't have been obvious otherwise, while also improving my sewing with each version.

03

I developed a workflow for translating sketch models into printable patterns in Illustrator, enabling more precise refinement and repeatability.
