Always inspect the bag, straps, and buckles before each use. 【Superior Waterproof Protection】Features waterproof PVC material, dual waterproof zippers, an extra-wide rain flap, and reinforced welded seams to effectively keep your luggage dry in rain, snow, or wet road conditions. Ensure all zippers are fully closed and straps are securely tightened before driving. 【21 Cubic Feet Storage Capacity】Measures 52" × 39.5" × 17.5" — offering generous space for luggage, camping gear, sleeping bags, strollers, and more. The flexible soft-sided design easily accommodates bulky or irregularly shaped items. Do not exceed 45 kg (99 lbs) load capacity or your vehicle manufacturer's roof load limit. 【Universal Fit for Most Vehicles】Compatible with most cars, SUVs, and vans — whether you have side rails, cross bars, or a bare roof. Please verify your roof can accommodate the bag size (52" × 39.5") and strap routing before purchase. 【Foldable & Space-Saving Storage】Unlike rigid hard-shell roof boxes, this soft bag folds down to a compact size for easy storage in your boot or garage. Simply wipe clean after use and stow it away until your next trip. Confirm your vehicle roof dimensions before ordering to ensure a proper fit.
