Backpack Thule Chasm Courier 22L with InLock (Mid Blue) – 22L capacity, InLock laptop/security system

The Thule 5469 Chasm Courier 22L with InLock in Mid Blue is a versatile courier-style bag designed for carrying up to 22 litres (approximately 11 kg) of clothing, groceries or daily gear. It attaches to a compatible bike rack using the Thule InLock universal panel (sold separately) and can be carried on the bike or across the body for off-bike use.

Advantages

The bag offers a comfortable on-bike or cross-body carry option with a detachable strap that stows under a flap while riding. Quick-access interior and front pockets keep essentials within easy reach, and reflective trim improves visibility. Durable, water-resistant materials protect contents and are easy to clean. When used with the InLock system the connection is soft and silent for a rattle-free ride.

Suitable for

• Commuting by bike with everyday items (clothing, lunch, small groceries)
• Urban errands and short grocery trips
• Travel or day trips where a compact, weather-protective bag is needed

When it may not be suitable

This 22L courier bag is not intended for carrying large or heavy loads beyond approximately 11 kg. It requires the Thule InLock universal panel to attach securely to most bike racks; the panel is not included. For specialised long-distance touring or very heavy cargo, a larger dedicated pannier or cargo system may be more appropriate.
