Waterproof? Airline-Proof? Theft-Proof? We Put the TREKARIUS 35L to the Test

We’ve all been there.

You’re sprinting through a downpour to catch a train.

Or squeezing into a budget airline seat, praying your bag isn’t gate-checked.

Or walking through a packed street market where everything feels like a target.

In those moments, your backpack can either fail or flex.

So we took the TREKARIUS 35L Travel Pack and ran it through real-world chaos to see how it performs when it matters most.

This is not a studio review. It’s a field test.

No brand bias. No babying.

Just rain, concrete, zip checks, and tight gates.

Real-World Test #1: Rain and Weather Resistance

Location: Lisbon, Portugal

Condition: 30 minutes of steady rain + sidewalk splash from taxis

Gear Inside: DSLR camera, laptop, dry clothing, cables

Result: Dry. Every. Time.

• The outer weather-resistant shell didn’t absorb or retain water

• Zippers are SBS, sealed tight—even where the shoulder strap meets the lid

• Inner tech pouch stayed bone dry

• Water beaded off the surface like wax

 Real-World Test #2: Carry-On Compliance & Airport Stress

Test Flights:

• Ryanair (strict under-seat personal item)

• Wizz Air (budget airline with tight carry-on rules)

• Lufthansa (standard carry-on)

Test Conditions: Fully packed with travel gear, tech, camera, and clothing

Result: Passed Every Airline Check

• Under-seat fit: With side compression straps cinched down, it fits Ryanair’s personal item checker

• Overhead bin:  Fits flat even when fully loaded

• No gate-check flags from any airline

• Weight felt balanced when carried through terminals (even for 3+ hours)

 If you’re looking for a carry-on durable backpack that won’t cost you extra in baggage fees, TREKARIUS is airline-proof.

Real-World Test #3: Urban Pickpocket Simulation

Location: La Rambla, Barcelona

Scenario: Deliberately tested zippers and placement in crowded public areas

Method: Simulated grab attempts, watched interaction points, wore in backpack mode and sling mode

Result: Designed With Discretion and Defense

• The valuables compartment sits flat against your back, making access nearly impossible when worn

• Admin panel zippers are hidden under a flap and tight when packed

• No flashy logos or obvious gear shapes—it doesn’t scream “steal me.”

• Materials are semi-rigid, making slashing attempts harder (and noisy)

Travelers often forget the importance of backpack safety. TREKARIUS bakes it in invisibly.

Real-World Test #4: Rough Handling + Drop Test

Scenario: Simulated chaotic transit

• Tossed into a van in Vietnam

• Dropped from waist height onto gravel

• Dragged across asphalt for 3 meters

Result: Zero Failures, Minor Scuffs

• Shell showed minor abrasion but no puncture or tearing

• Zippers remained sealed, no track damage

• Inner laptop and camera gear were unaffected

• Straps held firm with no stretch or snap

This isn’t a showroom bag. It’s a truly durable travel backpack made for travellers who treat airports like obstacle courses.

Real-World Test #5: Overpacking + Compression Test

Test Loadout:

• 3 pants, 3 shirts, 1 hoodie, 1 jacket

• Laptop, tablet, chargers, journal

• DSLR, tripod, drone, cables

• Toiletries and snacks

Result: Still Sleek, Still Balanced

• Bag took everything without bulging oddly

• Side compression straps made the profile slimmer, even when maxed out

• Still fit under-seat after compression

• Center of gravity stayed close to the back—no tipping or sagging

For those wondering if 35L is enough—it’s more than enough if the layout works. TREKARIUS proves it.

 Summary: What Makes TREKARIUS a “Proofed” Backpack?

Final Thoughts: Built for the Real Road, Not the Highlight Reel

TREKARIUS doesn’t just check boxes.

It survives checklists, checkpoints, and bad weather.

If you’re done with backpacks that:

• Soak your gear when the weather turns

• Get flagged at the gate

• Make you a target in crowded areas

• Break down after two trips...

Then this is your answer.

The TREKARIUS 35L is field-tested, creator-approved, and built to outlast your itinerary.
