If you’ve ever struggled through an airport dragging an oversized suitcase, sweating through connections, or paying unexpected baggage fees, you already understand why minimalist packing matters. This is the story of how we slowly and expensively evolved our travel setup from a large suitcase to a streamlined carry-on system centered around an Osprey travel backpack.
This wasn’t an overnight transformation. It took years of trial and error, wasted money, overpacking mistakes, and a lot of back pain to finally land on a system that works. If you’re trying to master carry-on travel or minimalist packing, hopefully this saves you from making the same expensive detours we did.
The Beginning: The Large Suitcase Phase
Like most travelers, we started with the classic large suitcase. It seemed logical at the time: more space equals more freedom, right?
Wrong.
The large suitcase quickly became a trap. We filled it because we could fill it. Instead of packing intentionally, we packed emotionally “just in case” items, extra shoes, multiple jackets, and things we never used.
The problems became obvious fast:
- Hard to maneuver through cobblestone streets and public transit
- Forced check-in fees on budget airlines
- Constant waiting at baggage claim
- Zero flexibility for spontaneous travel changes
We weren’t packing for travel. We were packing for anxiety.
The First Upgrade: 70L Backpack (The Illusion of Freedom)
Our first unintentional move toward minimalism was a 70L backpack. It felt like a breakthrough, finally, something mobile.
But it didn’t solve the problem. It just redistributed it.
A 70L backpack is still essentially a suitcase you wear. And of course, we filled it completely.
We learned quickly:
- More space still meant overpacking
- The load was heavy and uncomfortable
- It still often needed to be checked
- Mobility improved slightly, but not meaningfully
We hadn’t changed our habits. We had just upgraded the container.
The Adjustment: 60L Backpack (First Real Constraint)
The 60L phase was our first real attempt at discipline.
With slightly less space, we had to start making decisions. We began asking better questions:
- Do I actually use this?
- Can this serve more than one purpose?
- Will I wear this more than once?
For the first time, packing started to feel intentional.
But we were still not quite there. The bag didn’t meet carry-on requirements by most airlines. We were learning restraint—but not yet understanding true minimalism.
The Inspiration Moment: A Chance Encounter on a Bus to Explore Giant’s Causeway
The real shift didn’t come from gear. It came from a conversation.
During a bus trip to Giant’s Causeway in Northern Ireland, we met a couple traveling with nothing but small carry-on bags.
No checked luggage. No oversized backpacks. Just compact, efficient travel systems.
We were honestly amazed.
We remember asking them how they managed it. How they could possibly travel long-term with so little? They smiled like it was obvious and explained that they had simply learned to pack for what they actually used, not what they feared they might need.
That idea stuck with us.
At the time, it felt almost unrealistic. We had been conditioned to believe that more gear meant more preparedness. But here were two people moving through countries with ease, unburdened by luggage, completely unbothered by logistics.
It shifted something in us.
On the rest of that trip, we kept thinking about it, about freedom, weight, and simplicity. And for the first time, we started imagining a different way to travel.
The next trip, we tried it.
Just carry-on.
And we never looked back.
The Breakthrough: 55L Backpack (Where It All Changed)
When we finally committed to a 55L backpack, everything started to click.
This was the first time we truly had to pack with discipline. Every item had to justify its place.
We stopped asking “what if?” and started asking “how often?”
- Easier airport navigation
- Less physical strain
- Faster packing cycles
- Real carry-on compliance
This was the beginning of actual minimalist travel—not just reduced volume, but reduced mental load.
The Final Evolution: Osprey and Purpose-Built Travel
The final step in our journey came when we switched to travel-focused gear from Osprey.
This wasn’t just a size change—it was a design change.
Osprey packs are built for intentional travel. The organization, structure, and ergonomics fundamentally changed how we packed and moved. They also comply to all airline’s carry-on size requirements.
What made the difference:
1. Structured organization
Instead of one chaotic space, everything had a designated place.
2. True carry-on compatibility
No more guessing. No more gate-check stress.
3. Comfort under load
Even fully packed, the weight distribution made long travel days manageable.
4. Built-in packing discipline
The design itself discouraged overpacking.
At this point, minimalist packing stopped feeling like a challenge and started feeling like a system.
What We Learned From Years of Trial and Error
Looking back, every stage taught us something important:
- Bigger bags don’t solve packing problems—they hide them
- Constraints force better decisions
- Most “just in case” items never get used
- Travel becomes easier when logistics disappear
- Gear matters, but habits matter more
Here is an overview of what we learned:
| Travel Setup | Biggest Advantage | Biggest Problem |
|---|---|---|
| Large Suitcase | Maximum space | Heavy, expensive, inflexible |
| 70L Backpack | Better mobility | Encourages overpacking |
| 60L Backpack | Forces some discipline | Often exceeds carry-on limits |
| 55L Backpack | Carry-on friendly | Requires intentional packing |
| Travel Backpack System | Maximum freedom | Requires a minimalist mindset |
The Result: True Carry-On Travel
Today, everything we travel with fits into a single carry-on backpack.
No checked bags. No waiting. No excess.
And more importantly, no stress-driven overpacking.
That chance conversation on a bus to the Giant’s Causeway changed everything for us. It showed us that minimalist travel wasn’t about sacrifice—it was about freedom.
And once we experienced that freedom, there was no going back.
Frequently Asked Questions About Minimalist Travel and Carry-On Backpacks
What size backpack is best for carry-on travel?
For most travelers, a backpack between 40L and 55L offers the best balance between packing space and airline carry-on compliance. The ideal size depends on your travel style, clothing choices, and willingness to do laundry during your trip.
Can you travel long-term with only a carry-on backpack?
Yes. Many minimalist travelers successfully travel for weeks or months with a single carry-on backpack. The key is packing versatile clothing, planning for occasional laundry, and bringing only items that serve a clear purpose.
Why do people switch from suitcases to travel backpacks?
Travel backpacks offer greater mobility, especially when navigating airports, public transportation, stairs, cobblestone streets, and uneven terrain. Many travelers also appreciate avoiding baggage claim delays and checked baggage fees.
Is a larger backpack better for travel?
Not necessarily. Larger backpacks often encourage overpacking, which adds weight and complexity to your trip. Many travelers discover that a smaller backpack forces better packing decisions and results in a more comfortable travel experience.
How do I stop overpacking for trips?
Start by packing for your actual travel plans rather than hypothetical situations. Choose clothing that can be mixed and matched, plan to do laundry if needed, and eliminate items that are unlikely to be used. Most travelers use far fewer items than they initially pack.
What are the benefits of traveling with carry-on luggage only?
Carry-on-only travel allows you to move faster through airports, avoid checked baggage fees, eliminate the risk of lost luggage, and travel with greater flexibility. Many travelers find that carrying less also reduces travel stress.
How much clothing do I need for minimalist travel?
Most minimalist travelers pack enough clothing for approximately three to five days and then wash and rewear items throughout the trip. Quick-drying, versatile clothing makes this approach much easier.
What features should I look for in a travel backpack?
Look for a backpack that is carry-on compliant, comfortable to wear for extended periods, well-organized, durable, and designed specifically for travel. Features such as laptop compartments, compression straps, and easy-access pockets can make a significant difference during long trips.
Is minimalist travel about owning less?
Minimalist travel is less about owning fewer things and more about bringing only what adds value to your trip. The goal is to reduce unnecessary weight, simplify logistics, and increase freedom while traveling.
What is the biggest lesson from switching to minimalist travel?
The biggest lesson is that more luggage rarely creates a better travel experience. Most travelers find that packing less leads to greater flexibility, lower stress, easier transportation, and more enjoyment of the journey itself.
Final Thoughts
Minimalist travel didn’t happen for us because we read about it or planned it perfectly—it happened because we were tired. Tired of heavy bags, lost bags, paying for luggage fees, and tired of letting “just in case” thinking dictate how we travelled. Tired of all the worry it brought.
What we discovered along the way is that every step down in luggage size forced a step up in intention. Less space didn’t limit us—it refined us. It made us ask better questions, pack with more purpose, and ultimately travel with more confidence.
The truth is, the backpack itself was never the transformation. It was the mindset behind it. The shift from “What might I need?” to “What do I actually use?” changed everything about how we move through the world.
And once you experience travel without the weight—physically and mentally—it becomes very hard to go back. Airports feel easier. Transitions feel smoother. Decisions feel lighter. Travel starts to feel like movement and adventure again, not management.
Today, the Osprey system isn’t just our gear of choice—it represents how we travel now: simple, flexible, and focused on the experience instead of the equipment.
Because in the end, minimalist travel isn’t about having less.
It’s about making room for more of what actually matters: freedom, ease, and the journey itself.
