Thule Chasm spans compact backpack carry and larger travel/outdoor capacity. The live collection now includes multiple 26L backpack versions plus 40L Chasm products, giving the family a real size ladder.

Quick Answer

Choose Chasm 26L for laptop, work and everyday travel, and Chasm 40L when the repeated load includes more clothing or outdoor gear. The 26L versions are the more natural daily backpacks; 40L moves toward larger travel and gear carry.

Chasm 26L

Current Chasm 26L listings include laptop-oriented versions with 16-inch device fit and weather-resistant or water-resistant recycled materials. This makes 26L a strong work, commuter and short-trip option.

Chasm 40L

Forty liters is substantially larger and better suited to clothing, outdoor equipment and longer trips. It is more capacity than most ordinary office commuters need.

Laptop and Work Use

Choose the 26L version when a laptop is central to the load. Measure the device with its case and check the exact Chasm generation before buying.

Travel Use

Both sizes can travel, but airline compatibility depends on the fully packed exterior dimensions. A 40L soft bag can exceed a limit when overfilled.

Weather Resistance

Some current 26L product titles explicitly use weather- or water-resistant wording. That does not make every seam and zipper fully waterproof.
