Key features

Made from 700D PVC, this rooftop carrier uses a double layered waterproof cover with heat sealed seams to resist rain and splashes, according to the manufacturer. It ships with an anti slip topper mat and 10 reinforced adjustable straps to hold the bag steady at highway speeds. A luggage lock is included for basic theft deterrence, and six door hooks make installation possible on cars without side rails.

Usage tips

Install the bag on a clean, dry roof and place the anti slip mat between the bag and vehicle surface for extra grip. Tighten each of the 10 adjustable straps so the load sits flat and balanced, and secure the door hooks as instructed. Regularly check strap tension during long trips, especially after heavy rain or rough roads.

What to know

This is a soft rooftop cargo carrier not a hard shell. While seams are heat sealed and stitched for enhanced water resistance, the manufacturer notes that absolute waterproof performance is not guaranteed under extreme weather or improper use, so avoid overloading sharp items and follow the manual for strap placement and care. Worth considering if you need flexible, removable cargo space for tents, suitcases, sleeping bags, or bulky gear on SUVs and larger vehicles. 🧳🚗🔒
