Engineered for seamless vehicle mounting and everyday carry, the Thule Chasm 22L courier bag keeps your gear dry, organized, and securely fastened across varied terrain.

Manufactured from abrasion-resistant 420D nylon bonded to a phthalate-free laminate, this bag protects sensitive electronics, cycling apparel, and daily essentials from moisture, dust, and routine scuffs.

• Weatherproof fabric and high-visibility reflective piping eliminate worries about overnight rain damage or low-light exposure during dawn commutes.
• Dimensions of 16.7 x 14.8 x 8.7 inches and a lightweight 1.3-pound build create a slim profile that sits flush against roof rails without disrupting aerodynamics or obstructing license plates.
• Direct InLock panel compatibility delivers a smooth, rattle-free attachment that maintains structural integrity through potholes, hard braking, and uneven pavement.
• Soft-connection mounting hardware rests gently against bumpers and rooflines, resolving the common complaint of rigid brackets scratching factory paint or clearing over extended use.
• Rapidly transitions from fixed roof transport to a crossbody tote via a padded shoulder strap that tucks neatly under the main flap when hands-free riding stability is required.
• Externally accessible zippered compartments and internally structured slip pockets organize cables, phones, and documents without forcing you to remove the pack from your vehicle.
• Fabricated in Indonesia with reinforced stress points, the chassis resists tearing and seam separation, extending service life across seasons of frequent loading and unpacking.
