Topo Designs · Global Travel Bag 30L
A week in a 30-litre backpack that opens like a suitcase.
The Global Travel Bag 30L is the Topo Designs travel bag: a 30-litre backpack that opens in two like a suitcase and stretches to 35 litres when packed full. On the platform, you carry it on your back, hip belt buckled, the 15-inch in its compartment against your back. On the train, you stow the backpack straps and pick it up by the handle or sling it over your shoulder.

What fits inside
30L
30 litres packed flat, as in a suitcase: enough for a week.
The main compartment opens in a U and folds out flat, with mesh pockets inside. At the front, a second compartment, also with a U-shaped opening, has its own zipped security pocket and two patch pockets. Packed full, the bag goes from 30 to 35 litres.
- A week's worth of clothes, packed flat in the main compartment
- A 15-inch laptop, in the back compartment
- A water bottle in each stretch side pocket
Laptop
The 15-inch in the back panel, behind its own zip.
The laptop compartment sits in the padded back panel and opens with a zip of its own: you take the 15-inch out without opening the main compartment.
15 inches

In the rain
In a shower, the laptop and your papers travel better in a pouch.
Not made for rain
Recycled nylon fabric
In steady rain, water eventually gets through: anything that mustn't get wet goes in a pouch.

Water-resistant
Water-resistant fabric
The water-resistant fabric copes with a shower; in steady rain, water eventually gets through.
Water-repellent
PFC-free water-repellent finish
A PFC-free durable water repellent (DWR) finish makes water bead up on the fabric. It doesn't make the bag waterproof: in steady rain, water eventually gets through.
Before a day in the rain, slip the laptop and your papers into a pouch.

A sewing machine in a Fort Collins basement, in 2008.
Jedd Rose buys a sewing machine and sews the first bags in his basement in Fort Collins, Colorado; Mark Hansen asks around for people who can make them.
The two founders wanted gear like the kit they grew up with: tough, practical, classic, the opposite of throwaway and overcomplicated. The same bag goes from the city to the trail.
Topo Designs guarantees its bags against defects in materials and workmanship for a reasonable lifetime, excluding normal wear, accidents and lack of care, and would rather repair than replace. For a bag bought from Eiken, the claim goes through us.
Eiken's take
- Why we chose it
- A suitcase opening, a separate 15-inch compartment and three ways to carry it: a single bag for the week, which is still a backpack on the platform.
- Worth knowing
- Packed to 35 litres, it gets deeper, and the cabin margin is only 2.2 cm: measure it full before you fly.
- Who it's for
- A week with a single bag, by train or by plane, hands free on the platform: for anyone who doesn't want a suitcase. For two or three days, the Global Travel Backpack will do.

Under the seat, no: at 51 cm tall it's over both easyJet's under-seat bag (45 × 36 × 20 cm) and Ryanair's (40 × 30 × 20 cm). Size limits checked in October 2026: check with your airline.
What size laptop fits in the Global Travel Bag 30L?
Most 15-inch laptops, in a compartment set into the padded back panel. It has its own zip: the laptop comes out without you opening the main compartment.
Global Travel Bag 30L or Global Travel Backpack?
The Global Travel Bag 30L, 30 litres and 51 cm tall, is carried on your back, on the shoulder or by hand, with a removable hip belt: it's the bag for a week away. The Global Travel Backpack, 25 litres and 27 with the panel open, is still a backpack, for two or three days. Both open like a suitcase, take a 15-inch and slide over a suitcase handle.
