Based on a design from the 1950s, Brooks' Glenbrook Holdall is an excellent seat bag providing elegance plus roomy and easily accessed carrying capacity for errand-running or all-day adventuring. Waterproof textile and Brooks' trademark leather accents ensure your belongings travel safe and dry. The large main compartment and 2 side pockets provide plenty of options for organizing your gear. The Glenbrook attaches to the rear of your Brooks saddle (sold separately). A handy shoulder strap is included so you can use the bag off the bike, too.
