NIFCO® MAGNETIC CHEST BUCKLE
A one-touch magnetic snap connects instantly and releases with a single press for one-handed operation, keeping straps secure and preventing slippage.
STOWABLE SHOULDER STRAPS
Shoulder straps tuck away to avoid snagging during check-in or boarding; the strap ends can also detach individually via a 6-shaped hook clip — only the ends, not the entire strap.
TSA-APPROVED INTEGRATED LOCK
A built-in TSA-certified combination lock meets international security screening standards, eliminating the need for a separate padlock.
TWO-DEVICE LAPTOP BAY
A divided laptop compartment carries a laptop and a tablet at the same time, each in its own padded slot — not stacked, not jostling.
TWO HIDDEN BACK SECURITY POCKETS
Two concealed layers against the body side of the pack hold passports, wallets, and phones out of sight, adding a layer of anti-theft protection by design.
LUGGAGE PASS-THROUGH STRAP
A dedicated strap secures over a rolling suitcase handle, easing the strain of carrying the pack on longer journeys.
