35 → 60 L
Core technology
Standard pumps pull 4 kPa. This one pulls 60 kPa.
The Vortex pump is a USB-C diaphragm pump that fits in the palm of your hand — fifteen times the suction of the 4 kPa hand pumps bundled with budget vacuum compression bags. It charges like your phone and lives in the bag: nothing separate to pack, nothing to lose.

A 35 L bag that swallows 60
The Vortex Vacuum Seal® chamber reduces packed volume by up to 57% while the shell holds its shape. Removable seal bag and 60 kPa USB-C diaphragm pump included.
02
A TSA-approved lock, built in
A TSA-approved combination lock is integrated into the bag — no dangling padlock. Agents open it with a master key; the bag stays intact.
03
Weatherproof to the seams
YKK® AquaGuard® zippers and X-Pac® laminate seal the shell; the Vortex chamber is Waterproof (IPX8) — rated for full submersion. Your clothes stay dry.
04
A built-in tech pouch
A dedicated front-pocket organizer engineered to the millimetre — elastic loops, card slots and a padded sleeve for phone, AirPods, cables, mouse and boarding pass. Everything in its own place, first reach.
05
A hidden pocket against your spine
A concealed back-panel pocket flat against your spine — invisible to pickpockets, out of reach in a crowd. Passport, cash and cards ride where only your own hand can go.

QUESTIONS
Questions, answered
Q.01
Is it heavy?
Packing 60L will always carry real weight — and in our travel backpack series, the Zephyr Pro isn't even the heaviest. The heft is a balance: comfort padding, a padded laptop bay, YKK® AquaGuard® zippers, a TSA-approved lock and the front tech pouch. If you'd trade functionality and padding for grams, our Aero series is the lightweight line. For reference: the Cordura build is 2.37 kg; X-Pac is 2.2 kg.
Q.02
Will the vacuum seal erupt mid-trip?
No — and this is where the Zephyr Pro separates from cheap imitations. Compressed clothing pushes outward the whole trip, and on budget bags it's the seal or the zipper that gives out first, especially stuffed to the max. The Vortex Vacuum-Seal chamber is rated Waterproof (IPX8) — the only travel backpack compression chamber with that rating — and its dual-seal TPU structure with YKK® zippers is built for exactly that outward pressure. One seal holds up to 168 hours: out and back, cabin pressure included.
Q.03
Is 60L smaller than it sounds?
35L is the everyday footprint; 60L is what it holds expanded. Compression is what lets the 35L frame swallow a checked bag's worth. Exact dimensions: 50 × 35 × 19 cm.
Q.04
How strong is the pump, really?
60 kPa — fifteen times the 4 kPa hand pumps bundled with budget vacuum compression bags. It's built in and charges over USB-C, so there's no separate pump to pack or lose.
Q.05
What if it's not for me?
You have 30 days to return it. And US orders over $200 ship free — which covers every Zephyr Pro configuration.
