About
What it is.
Part of Thule's Subterra line of travel packs, this model sits in the category of structured carry-on backpacks built around expandable volume rather than fixed capacity. The shell is bluesign-approved 800D nylon/polyester, water-resistant, and paired with a padded compartment sized for a 16-inch laptop and a 10.9-inch tablet, plus an organization panel for the interior. A removable packing cube handles compression for clothing, and a luggage pass-through strap lets the pack ride on top of rolling luggage.
The design favors travelers who want one bag that can shift between day use and packed travel days, with a sleeker, more tailored profile suited to business or mixed-purpose trips rather than trail-style comfort or heavy external organization.

Frequently asked
What buyers want to know.
What is the Thule Subterra 2 Travel Backpack 40L best for?
Reviewers say it works best for travelers who need a structured, professional-looking carry-on that can switch between day use and packed travel days. It suits business trips or mixed-purpose travel where a sleek profile matters more than external pockets or maximum comfort over long distances.
How durable is the Subterra 2 40L?
The pack uses bluesign-approved 800D nylon paired with YKK zippers and Duraflex buckles. Reviewers describe the hardware and fabric as strong and well-built, with a water-resistant shell that holds up to regular travel use.
What carrying options does it have?
You can carry it as a backpack, use the briefcase-style handle, or switch to a detachable shoulder or crossbody strap. The straps hide away when not in use for a cleaner look. One reviewer preferred the crossbody strap over the backpack harness for comfort.
What are the downsides?
Reviewers flag that the harness system and back panel have little ventilation and can feel uncomfortable on all-day wear, especially in warm climates. There's no external water bottle pocket, and the sternum strap attachment can feel flimsy. The pack also has minimal external organization overall.
How much does it hold and what fits inside?
The 40L capacity is expandable. It has a padded compartment for a 16-inch laptop and 10.9-inch tablet, an interior organization panel, a removable packing cube for clothes compression, and a hidden passport pocket. A luggage pass-through strap lets it sit on top of rolling luggage.
Does it look bulky when you wear it?
Reviewers describe the design as sleek and minimal with a professional appearance that doesn't look bulky when worn, making it suitable for business settings or mixed travel where appearance matters.
