Briefcase or backpack?
Choose the briefcase if you want a bag that works in meetings and lies flat on a desk. At 10cm deep it is the slimmest of the three, and it is rated 4.88 out of 5 from 17 customer reviews.
Choose a backpack if you walk or cycle to work, or want both hands free at the airport. The Laptop Backpack is the lighter, slimmer option at 1kg and 15cm deep.
The Travel Backpack is 17.5cm deep, giving you the most room of the three for a change of clothes, chargers and documents on a work trip.
Will it fit under the seat on a plane?
We compared each bag's listed size with the free under-seat (personal item) allowance of three UK airlines:
| Bag | easyJet 45 × 36 × 20cm |
British Airways 40 × 30 × 15cm |
Ryanair 40 × 30 × 20cm |
|---|---|---|---|
| 17" Laptop Briefcase | Fits | No: 41.5cm wide | No: 41.5cm wide |
| Laptop Backpack | Fits | No: 41cm tall | No: 41cm tall |
| Travel Backpack | Fits | No: 42cm tall | No: 42cm tall |
On British Airways and Ryanair, a 17" bag is just over the under-seat size, so count it as your cabin bag instead. Allowances change, so check your airline before you fly. Our cabin bag size guide lists the full limits for UK airlines.
Check your laptop, not just the screen size
Laptop sizes are measured diagonally across the screen, so two 17" laptops can be different widths. Measure your closed laptop's width and depth before you buy. If you're between sizes, our 15" vs 17" briefcase guide compares every briefcase we make.
What they're made from
All three bags are full-grain, vegetable-tanned cowhide that develops a patina with use. Our leather explained. The linings are made from 100% recycled materials.
