Ortlieb X-Tremer waterproof expedition bag

Ortlieb X-Tremer: maximum capacity, absolute waterproofing

When the mission demands truly large volumes — caving, expedition kayaking, overland travel, multi-week wilderness trekking — the X-Tremer answers with 100% waterproof construction in 113-litre and 150-litre formats. It replaces rigid Pelican-style cases and unwieldy barrels for the majority of expeditions where the goal is complete protection without carrying a container.

Roll-n-snap — the reliable seal

The roll-n-snap closure requires no electronics, no batteries and no moving parts to fail in the field. Three to four rolls plus one buckle click creates an absolute waterproof seal. The X-Tremer has been tested in conditions that rule out everything with a zip.

Worn or loaded

Anatomical padded shoulder straps with a chest strap allow the X-Tremer to be carried on the back when the terrain demands it. On vehicles, boats or racks, the bag’s robust construction and attachment points make it a reliable transport container.
