-   Loop mounts on top let you strap down a tent, sleeping mat, or fuel bottle
-   Modular system means you can scale from a day's worth of gear up to a full overlander rig
-   Over-the-seat harness lets you mount OS-6, OS-12, or OS-18 Adventure Packs as panniers
-   Quick on / quick off once the initial setup is dialed
-   10-year warranty against manufacturing defects
-   OS-Rack Loop mounting system handles serious off-road abuse

Here's the deal — the Os-Base Adv is the modular foundation of the Kriega Overlander system, dialed in for your bike. Heavy-duty Hypalon construction with a semi-rigid polypropylene core gives you a stable harness that won't sag or shift under load. Mount OS-6, OS-12, or OS-18 Adventure Packs (sold separately) as panniers, then add a top bag for up to 54 liters of total waterproof capacity. The OS-Rack Loop mounting system handles real off-road riding without working loose. Lightweight, low-profile when not loaded, and quick to put on or take off after the initial setup. Compatible with earlier Overlander 15 packs as panniers and US-Drypacks as top bags. Designed to fit your bike cleanly without fabrication. We sell this to dual-sport and adventure riders running bikes that don't have factory pannier racks, or who want a lighter, more flexible mounting setup than a full hard rack. Pair it with OS-6, OS-12, or OS-18 Adventure Packs (sold separately) and add a top bag for serious capacity. Up to 54 liters total, all fully waterproof. Comes with Kriega's 10-year warranty.
