Who it fits

Key specs explained

Capacity: 30 cu ft

This volume tells you how much gear fits inside. You can store large items like suitcases, tents, or sleeping bags. It matches the space of a small roof box. This capacity suits families needing extra room for weekend trips. It is smaller than 40 cu ft options, so you save weight and cost. Check your gear dimensions to ensure a good fit.

Dimensions: 60 x 24 x 36 inches

These exterior measurements show the bag’s footprint. The 60-inch length extends well behind your vehicle. The 24-inch width fits standard hitch receivers. The 36-inch height may block rear lights on some trucks. Measure your hitch area carefully. This size is longer than most roof boxes, so you need clearance for doors and ramps. Plan your parking spots accordingly.

Shell Type: Soft shell

A soft shell is made of flexible material, usually vinyl or fabric. It folds flat when not in use, saving storage space at home. It is lighter than hard plastic roof boxes. However, it offers less impact protection for fragile items. You must secure the contents well. This type is ideal for camping gear or soft luggage that does not require rigid protection.

Water Resistance: Waterproof

This rating means the material and zippers block water entry. The bag includes protective flaps and sealed seams. You can leave it open during rain without worrying about wet gear. This is crucial for outdoor activities. Hard roof boxes also offer weather protection, but soft bags rely on material quality. Verify the zipper seals are intact before long trips.

Installation: 3 heavy-duty buckle straps

These straps secure the bag to your hitch receiver. They replace the rigid mounting arms found on hard carriers. Buckles allow for quick setup and removal. They may loosen over time on rough roads, so check them often. This method is less stable than bolt-on systems. Ensure the straps are tight to prevent swaying. This is a common feature for hitch-mounted soft bags.

Design And Build Details

According to the listing, the shell is made from heavy-duty, abrasion-resistant vinyl. This material choice aims to provide a sturdy, waterproof build for the bag. The exterior features a protective flap with Velcro closures over the zipper, which helps keep belongings dry in challenging weather. Reinforced seams are included to guard against tears and wear during use. The finish is black with orange trim, offering a high-contrast look that may improve visibility on the road.

The bag measures 60 by 24 by 36 inches and weighs 20 pounds. These exterior dimensions define the space you can occupy on your hitch receiver. The 30 cubic feet of capacity allows for large items like suitcases or camping gear. The soft-shell construction means the bag will conform to the shape of your cargo, maximizing the use of the available volume. It is not a rigid box, so it may shift slightly if not secured properly.

For organization, the package includes six soft black packing cubes. Each cube measures 29 by 23 by 12 inches and features double zippers. These cubes allow you to pre-pack items for easier loading and unloading. You can use them inside the main bag or separately in truck bed storage. The layout is flexible, letting you adjust your packing strategy based on the trip length. The soft material also allows the bag to fold for compact storage when not in use.

Setup And Everyday Use Guide

Installation relies on three heavy-duty buckle straps. You secure the bag to your vehicle’s hitch receiver using these straps. The listing does not mention tools, so you likely tighten them by hand. This method keeps the carrier stable on rough roads. The soft-shell design allows the bag to conform to the hitch shape. This flexibility helps with mounting compared to rigid boxes.

For daily use, the waterproof vinyl shell and protected zipper keep gear dry. The Velcro flap covers the zipper to prevent water ingress. You can load items directly into the main compartment or use the included packing cubes. The bag comes with six soft black cubes. Each cube measures 29 by 23 by 12 inches and holds up to 90 pounds. These cubes have double zippers for easy access. You can pack them separately or place them inside the main bag. This setup helps organize luggage for road trips or camping.

Security is handled by a combo lock. You use this lock to secure the zipper, adding anti-theft protection. When you are not traveling, the bag folds down. The listing notes that it folds for compact storage inside one of the packing cubes. This makes it easy to store in your garage or trunk. The 10-year limited warranty covers lasting performance. This setup is practical for hitch mounts and truck bed storage. You get reliable organization without bulky cases.

Check Compatibility Before Buying

Before you purchase this Mockins bag, verify your vehicle’s hitch receiver size. The listing specifies three heavy-duty buckle straps for installation, but it does not list compatible hitch dimensions. You must ensure your receiver matches the strap length and width. This soft-shell carrier adds significant bulk to your rear. Its exterior dimensions measure 60 by 24 by 36 inches. Check your rear visibility and clearance before loading gear. The bag weighs 20 pounds empty, so factor that into your total load capacity. You should also inspect your hitch bolts for tightness after initial use. Since this is a soft-shell option, it sits alongside rigid roof boxes and hard plastic carriers in this category. Unlike rigid carriers, this bag offers flexible packing with included cubes. However, it lacks the aerodynamic profile of hard cases. Consider your driving habits. If you frequently drive on rough roads or in high winds, a rigid carrier might provide better stability. This bag suits those prioritizing volume over aerodynamics. Keep the vinyl clean to maintain waterproof integrity. Store it folded when not in use to save space.

Check before you buy

• Verify hitch receiver size matches strap specs.
• Check rear visibility with bag installed.
• Ensure vehicle weight limit allows 20 lb empty weight.
• Confirm strap length fits your hitch receiver.
