Built to withstand frequent use on road trips, camping, and outdoor adventures. 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. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0CB43ZBQZ | | Automotive Fit Type | Universal Fit | | Best Sellers Rank | 2,648 in Automotive ( See Top 100 in Automotive ) 6 in Roof Racks & Boxes | | Brand Name | Signstek | | Closure Type | Zipper | | Colour | Black | | Country Of Origin | China | | Customer Reviews | 4.5 4.5 out of 5 stars (203) | | Included Components | Anti-Slip Mat, Car Roof Bag | | Item Dimensions L x W x H | 132.1L x 100.3W x 44.5H centimetres | | Item Type Name | Car Roof Bag | | Item Volume | 21 Cubic Feet | | Manufacturer | Signstek | | Manufacturer Part Number | 21 Cubic | | Manufacturer Warranty Description | 1 | | Material Type | Polyvinyl Chloride (PVC) | | Model Number | 21 Cubic | | Mounting Type | Roof Mount | | Number of Items | 1 | | Number of Packs | 1 | | Shell Type | Soft | | Unit Count | 1.0 count | | Water Resistance Level | Waterproof | ## Product Details - **Brand:** Signstek - **Colour:** Black - **Material:** Polyvinyl Chloride (PVC) - **Product dimensions:** 132.1L x 100.3W x 44.5H centimetres - **Water resistance level:** Waterproof ## Images ![Signstek 21 Cubic Feet Waterproof Car Roof Bag - Image 1](https://m.media-amazon.com/images/I/71sNP6mCxcL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: Can this go on top of roof bars for a roof box** A: I used it without issue on my MG ZS-EV for a festival.
