This Chasm 130L Travel and Duffel Bag in black from Thule is the last bag you will ever need. Your gear is easily accessed through the oversized, wide-mouth opening. The bag converts from a duffel to a backpack and the backpack straps tuck away when you aren't using them.

The tarpaulin fabric is durable and weather resistant to protect your contents from the elements. The internal mesh pockets keep small items organized and easy to locate. The bag has zipper pulls you can secure with an optional lock to keep your gear secure.
