The Transit weatherproof duffle bag is appropriate for any occasion and ready for all conditions. For optimal use, add the Transit : Duffle Backpack Harness. We’ve added four cargo pockets to the outside of the bag to grab and stash gear when quick access is key. Inside the bag there are four additional cargo pockets and a separate zippered padded laptop sleeve. Multiple carry options include: hide-away grab handles, a removable-quick adjust shoulder strap and for times when the load is heavy, an optional backpack harness that can be ordered separately. In addition, the bag securely attaches to a front porteur style bicycle rack.
