A durable, waterproof, barrel-shaped holdall for expedition use. Ortlieb's Duffle uses waterproof fabric, waterproof construction & a waterproof Tizip closure to completely lock-out water, & for travel security, the zip can be locked closed with a padlock (not included). The underside is extra-tough to withstand the rigours of exploration, & the adjustable padded handles allow you to sling it on your back like a rucksack for easier carrying.
