Introduction

This manual provides essential information for the proper use, setup, and maintenance of your Thule 18L Commuter Backpack. Please read this manual thoroughly before using the product to ensure optimal performance and longevity.

The Thule 18L Commuter Backpack is an aerodynamic, expandable backpack designed for daily use, whether you are cycling or simply carrying your essentials. Its thoughtful design integrates features for convenience and comfort.

Key Features

  • Easy access to your smartphone on the go thanks to the dedicated bag.
  • Attach your helmet to the outside of the bag when dismounting your bike.
  • External pockets keep your bike lock and personal items within reach without having to dig deep into the bag.
  • The suspended laptop compartment sits comfortably on your back in a natural riding position and holds laptops up to 16 inches.
  • The front expandable pocket holds a helmet when dismounting your bike or a jacket or an extra pair of shoes.

Setup and Adjustment

Proper adjustment of your Thule backpack ensures comfort and stability, especially during cycling.

  1. Shoulder Straps: Adjust the shoulder straps so the backpack sits high on your back, distributing weight evenly. The top of the backpack should be level with your shoulders.
  2. Sternum Strap: Fasten the sternum strap across your chest and adjust its height and tension for added stability and to keep the shoulder straps from slipping.
  3. Waist Strap (if applicable): If your model includes a waist strap, fasten it around your hips. This helps transfer weight from your shoulders to your hips, improving comfort for heavier loads.
  4. Load Lifter Straps (if applicable): These straps connect the top of the shoulder straps to the top of the backpack. Tighten them slightly to pull the top of the pack closer to your body, reducing sway.

Operating Instructions

Packing Your Backpack

To maximize comfort and stability, pack heavier items closer to your back and centered. Utilize the various compartments for organization.

  • Main Compartment: Access the main compartment via the roll-top closure. This area is suitable for larger items like clothing, books, or groceries.
  • Laptop Sleeve: The dedicated suspended laptop sleeve protects your device (up to 16 inches) from impacts.
  • Front Expandable Pocket: Use this pocket for items you need quick access to, such as a helmet, jacket, or an extra pair of shoes.
  • Side Pockets: Ideal for water bottles or other small items.
  • External Zippered Pockets: Securely store smaller essentials like your phone, keys, or bike lock.

Using the Helmet Attachment

The backpack features an external attachment point for your helmet, allowing you to secure it when not riding.

  1. Locate the helmet attachment straps or loops on the exterior of the backpack.
  2. Thread the straps through your helmet's vents or use the loops to secure it firmly against the pack.
  3. Ensure the helmet is snug and does not swing freely, which could affect balance.

Care and Maintenance

Proper care will extend the life of your Thule backpack.

  • Cleaning: Spot clean with a damp cloth and mild soap. Do not machine wash, tumble dry, or bleach.
  • Drying: Air dry completely before storing to prevent mildew. Do not expose to direct heat.
  • Storage: Store in a cool, dry place away from direct sunlight when not in use.
  • Water Resistance: The backpack is designed with water-resistant materials. While it offers protection against light rain, it is not fully submersible.
