Forged for Extra Space: Asinking 21 Cu Ft Waterproof Rooftop Cargo Carrier Bag In-Depth Review
Introduction
The Asinking Car Rooftop Cargo Carrier Bag (21 Cubic Feet) is a heavy-duty, 100% waterproof soft-shell roof bag that fits vehicles with or without roof racks. Made from abrasion-resistant 840D PVC laminated tarpaulin, it offers massive storage for luggage, camping gear, sleeping bags, and more—perfect for road trips, moving, or family vacations. With features like an anti-slip mat, 6 door hooks, extra straps, luggage lock, and storage bags, it’s designed for secure, weatherproof hauling without a hard case. Popular for its value and ease, it’s a top choice for those needing extra space without permanent roof modifications.
Design and Build Quality
The Asinking bag uses thick 840D double-coated PVC fabric with heat-welded overlapped seams and a 3-sided watertight zipper with storm flap for superior waterproofing (IPX66 rated). The arched, aerodynamic shape reduces wind noise and drag, while reinforced straps, robust buckles, and widened flaps ensure stability.
Build quality impresses for the price—durable and flexible enough to conform to various roofs. Users praise the sturdy material and strong stitching that holds up to rough use. The bag lacks rigid structure (it’s soft-shell), so it may sag if overloaded, but it packs small when empty. Minor zipper or strap wear occurs over time, but no widespread structural failures reported.
Key Features and Specifications
- Capacity: 21 cubic feet (approx. 52″ L x 40″ W x 18″ H when full)
- Material: 840D abrasion-resistant PVC laminated tarpaulin (heavy-duty, waterproof)
- Waterproof Rating: IPX66 (fully sealed seams, storm flap zipper)
- Mounting: Universal—fits with or without roof racks; 6 padded door hooks + extra straps
- Extras: Anti-slip mat, luggage lock, storage bags, 2 additional straps
- Aerodynamics: Curved/arch design reduces noise, fuel loss, and wind rip risk
- Compatibility: All vehicles (sedans, SUVs, minivans, trucks); no rack required
The soft-shell design folds compactly for storage, unlike hard carriers.
Setup and Ease of Use
Installation is quick and tool-free: Spread the anti-slip mat on the roof, drape the bag, hook the 6 door straps, tighten buckles, and secure with extra straps/lock. Takes 10-15 minutes.
Users love the straightforward process—no permanent mods needed. The bag conforms to the roof shape, and the mat prevents slipping. Loading is easy (open wide zipper), but overpacking can make it floppy. Always double-check straps before driving.
Performance
On the road, the Asinking bag excels in waterproofing—stays dry in heavy rain thanks to sealed seams and flap. Aerodynamic shape minimizes noise (much quieter than hard boxes) and drag (better MPG than expected). Straps keep it stable at highway speeds when properly tensioned.
Real-world tests show it handles long trips well, with no ripping or major shifting. Wind can cause some flapping if loose; extra straps help. Durability is solid for occasional use, but avoid overloading or extreme winds.

Cons

Pricing and Value for Money
Typically $70-100 on Amazon (often on sale), the Asinking bag offers outstanding value—cheaper than hard carriers with similar capacity and better waterproofing than many soft bags. Thousands of reviews praise it as a “game-changer” for extra storage without breaking the bank.
