What Stands Out
Hard-shell protection with a built-in password lock and USB Type-A plus Type-C ports is limited to the Ratio Arc and Arc Pro; the Arc Pro takes a 17-inch (30x43x3cm) laptop, while the Arc is rated for 17.3 inches in a 45x31x9-10cm shell.
Expandable capacity is the Expandos range's edge: the Protector II adds a 30% expandable body (20L to 26L) and TSA combination lock, while the Expandos Expandable variants add body depth the Non-Expandable Classic Black listing does not.
Carry format variety is genuine rather than cosmetic: the ToteShift and Patchwork Tote are totes, the ToteShift with a detachable crossbody strap, and the TransitPro is a 39L weekender duffel with a shoe compartment and waterproof toiletry pouch.
Comfort-focused builds appear where named: the VaultCharge uses an EVA diamond bumper around a 15.6-inch sleeve at 0.91kg with a dual-zone breathable back panel, the ArmorShield uses a DWR water-repellent finish at 700g, and the AeroPro adds an elastic suspension base and 3D AirMesh back at 0.95kg.
What to Check
Laptop sizing is model-specific and not interchangeable: the VaultCharge and Patchwork Tote top out at 15.6 inches (Patchwork sleeve 36x22x4cm), the ArmorShield is stated for a 16-inch MacBook, the Protector II is sized for 15.6 inches, and the 17.3-inch claims on the Arc, the 17.3-inch AeroPro and the 17-inch Arc Pro each need checking against their own she…
Water resistance varies by product and should not be read across the range: the Arc, Arc Pro and Protector II are described as hard-shell waterproof, the ArmorShield and ToteShift are water-repellent or splash-resistant only, and the AeroPro fabric is splash-resistant, not waterproof.
Variant selection changes what you receive: the Expandos Classic Black listing is Non-Expandable, and the expandable body depth belongs to the Expandable, Expandable + YKK Zipper and Expandable + Raincoat variants, so confirm the variant name before ordering.
The Protector II charging port is integrated and non-removable, so plan around a fixed cable rather than a swappable one.
Product Review
1. Expandos: Versatile Expandable Laptop Backpack For All-day Traveling
Product overview
The dedicated compartment fits 15.6 to 17.3-inch laptops, and the external USB port lets you charge a device while the pack stays on your back. This Classic Black listing is the Non-Expandable version, so if you need extra depth for a trip, choose an Expandable variant instead. Confirm the exact variant at, since the range mixes fixed and expandable bodies.

3. The Ratio Arc: MarkRyden First Kickstarter campaign - Hard-shell Waterproof Laptop Backpack
Product overview
The integrated combination lock and hard-shell build support leaving the bag's secured compartments closed during commutes, while the 12.9-inch tablet sleeve keeps a second device separated from the 17.3-inch laptop. This suits buyers carrying both devices daily, but the 45 x 31 x 9-10cm shell still needs a physical fit check for your specific laptop.

That fits commuters and short-trip travellers who want one bag to grow. Note the charging port is integrated and non-removable, so confirm your cable and power bank approach before buying.

7. ToteShift: 16L Water-Resistant Laptop Tote Bag with Detachable Crossbody Strap

The ToteShift’s main compartment is sized to hold a 16-inch MacBook Pro alongside an 8.3-inch iPad mini 7, and the detachable crossbody strap lets you switch to shoulder or hand carry for commutes.

8. TransitPro: Business Travel Duffel Bag for Men – Large Weekender Carry On
Product overview
The TransitPro organizes a short business trip around separate shoe and toiletry storage, while the front organizer pockets keep smaller travel items in order rather than loose in the main compartment. It suits a professional carrying a 39L weekender by hand, crossbody or shoulder strap, but since no laptop compartment or device protection is documented, carry tech separately or confirm fit before relying on it as your work bag.

9. AeroPro: 17.3" Laptop Backpack with Enhanced Support for Travelers - Camouflage Black

10. Patchwork Tote: Laptop Tote Bag with Patchwork Design for Professionals
Product overview
The patchwork tote's shock-absorbing foam partition gives a 15.6-inch laptop a padded, dedicated slot inside the 36 × 22 × 4 cm compartment, so professionals who commute with a standard work laptop get a structured carry option rather than a loose sleeve. The bone shoulder pad and stretch expansion suit shoulder-carry days with a water bottle in the side pocket. Check your device against the compartment dimensions, since larger laptops will not fit.

Buying Notes
- Match the listed variant to your laptop and travel needs before ordering: the Expandos Classic Black here is Non-Expandable, while the Expandable, Expandable + YKK Zipper and Expandable + Raincoat variants add body depth; the Protector II expands from 20L to 26L but its laptop compartment is sized for 15.6 inches, not 17 inches.
- Measure your device against the stated compartment or body dimensions rather than relying on the inch label: Ratio Arc Pro lists a 30x43x3cm fit for 17-inch laptops, Ratio Arc and AeroPro list 17.3-inch compartments, VaultCharge and Patchwork Tote top out at 15.6 inches, and ArmorShield's 16-inch fit is stated for MacBook, so check other laptops against its 32x18x40cm body.
- Confirm the electronics and lock details that differ between models: the Ratio Arc and Arc Pro include a password lock with USB Type-A and Type-C ports, Protector II lists a TSA combination lock and an integrated non-removable charging port, and TransitPro has no documented laptop compartment or device protection, so plan to carry tech separately.
- Judge weather protection by the stated finish, not the headline: ToteShift is splash-resistant only, AeroPro uses splash-resistant fabric, and ArmorShield relies on a DWR water-repellent finish, so none of these should be treated as fully waterproof in heavy rain.

Final Verdict
Choose the Expandos MR9299 in one of the Expandable editions if you carry a 15.6- to 17.3-inch laptop and want the bag to grow for trips; check the listed edition tiers first, because the non-expandable version has a fixed body.
The Ratio Arc Pro MR8918 suits a 17-inch laptop and 12.9-inch tablet on commutes where the combination lock and hard ABS shell matter; confirm the lock setup meets your airline's screening needs before flying.
For a lighter 15.6-inch carry, the VaultCharge MR2022 keeps the load at 0.91 kg with a padded EVA laptop bumper; verify your device dimensions, as its 18.5L body suits daily work gear rather than bulky loads.
FAQ
The Arc and Arc Pro share a shell size — which laptop fits each?
The Arc is rated for a 17.3-inch laptop and the Arc Pro for a 17-inch (30 × 43 × 3 cm) laptop, plus a 12.9-inch tablet in both. Both use the same 45x31x9-10cm body, so compare your device's actual dimensions rather than the nominal screen size alone.
Does the Expandos Classic Black offer expandable storage?
No — this Classic Black listing is the Non-Expandable base model, so it has no extra body depth. The range documents separate Expandable, Expandable + YKK Zipper and Expandable + Raincoat variants if you need the extra capacity.
Can I return a bag I've used, and does the warranty cover wear?
Returns are accepted for unused and undamaged items within 14 days of receipt for non-custom items. The one-year warranty covers functional damage from normal use but excludes misuse, normal wear and tear, cosmetic issues, accidental damage and machine-washing damage.
