Not to be overlooked, THE MARSUPIUM has secret capabilities. This agile shoulder bag is a smaller sibling to our messenger style bags. The adjustable heavy duty nylon strap with side release clip and a quick pull D ring can be tucked away when its time to ride. Mountable to your rack or handle bars with hidden velcro tabs, it allows you to cycle bag free. A reinforced back plate keeps your bulkier belongings from interfering with your wheel, and a zippered details pocket secures your smaller vitals.
