Hitch Carriers
The Best Cargo Bags for a Hitch Carrier
An open basket will carry anything and protect none of it. The bag is the part that makes a carrier usable in rain, and the choice is narrower than you would expect.

The pick is the RoofPax car roof bag, and the honest reason is that it is the most genuinely waterproof bag of the three that will sit in a basket. If you would rather buy the bag and the basket in one order, the Mockins hitch cargo carrier normally ships with a bag, a net and straps included.
Now the thing nobody selling these will tell you: there is no such product as a hitch-carrier-specific cargo bag from any major brand. Every bag on the market is designed and marketed for a roof, because that is where the volume is. People use them in baskets anyway, they work, and the fit is a compromise you should go into with your eyes open.
What makes a roof bag work in a basket: a rectangular shape, a waterproof construction rather than a water-resistant one, and strap loops around the perimeter rather than only on the top face. What makes one fail: a shaped-for-a-roof profile that will not sit flat, a zip that faces upward into the rain, and door-hook straps that have nothing to hook to.
A basket bag also lives a harder life than a roof bag. It sits directly in the spray thrown up by your own rear wheels, which is dirtier and more constant than anything a roof sees. Expect it to look worse, sooner. Our roof cargo bag roundup covers the same products in their intended habitat.

#1 · Best overall — genuinely waterproof
RoofPax Car Roof Bag
A fully waterproof bag sold with door-hook straps, so it works with or without a rack — and works in a basket if you ignore the hooks and strap it to the frame.
- Type
- Waterproof soft bag
- Sold with
- Door-hook straps
- Designed for
- Roofs, bare or racked
- In a basket
- Strap to the frame, not with the door hooks
What works
- Waterproof rather than water-resistant, which is the whole point of a bag
- Rectangular shape sits flat in a basket floor
- Works on the roof too, so it is not a single-purpose purchase
- Straps included, which saves a separate order
What doesn’t
- The door-hook straps are useless in a basket — you will strap it to the frame instead
- Sits in your own rear-wheel spray, so it gets filthy fast
- No basket-specific sizing, so measure your floor before ordering
Our scoring
8.0overall
#2 · Bag and basket in one order
Mockins Hitch Cargo Carrier
A steel basket usually bundled with a waterproof bag, a net and straps — the quickest route from nothing to a covered load.
- Material
- Steel basket
- Usually bundled with
- Waterproof bag, cargo net, straps
- Shank
- Fixed on most variants
- Weather protection
- From the bag, not the basket
What works
- One purchase instead of four, with the bag sized to the basket it ships with
- The bundled bag is the difference between a basket and weather protection
- Cheapest route to a working, covered carrier
What doesn’t
- Bundle contents vary by listing — read what is actually in the box
- Bag and net are adequate rather than good, and the bag is the first thing to wear out
- You are buying a basket you may not need if you already own one
Our scoring
7.4overall
#3 · Best mid-size soft carrier
Rightline Gear Sport 2
A mid-size soft carrier designed to work on bare roofs using straps routed through the door frames — which means it is built to be strapped to a structure rather than clipped to a rack.
- Type
- Soft carrier
- Size
- Mid-size
- Designed for
- Bare roofs, strap-routed
- In a basket
- Strap through the basket mesh
What works
- Built around being strapped to something, which is exactly what a basket is
- Mid-size suits a 60 x 20 in basket floor better than a full-size roof bag
- No rack needed, so nothing to be incompatible with
What doesn’t
- No live Amazon listing matched this model, so we show no price for it
- Water-resistant construction rather than fully waterproof
- Soft sides mean it slumps unless you pack it full
Our scoring
7.5overall
#4 · The part most people forget
Rhino USA Cargo Net
A heavier bungee net with steel hooks, sized for hitch and roof baskets — because a bag keeps the rain out and a net keeps the contents in.
- Type
- Bungee cargo net
- Hooks
- Steel
- Sized for
- Hitch and roof baskets
- Use with
- A bag, not instead of one
What works
- Stops the small, light items that leave a basket at 60 mph
- Steel hooks survive being hooked into a steel basket repeatedly
- Works over a bag as a second layer of restraint
- Costs a fraction of anything else on this page
What doesn’t
- A net is not weather protection and never will be
- Bungee stretches over time and needs replacing
- Hooks can scratch a painted basket at the contact points
Our scoring
8.0overall
Why nobody makes a basket-specific bag
Follow the volume. Roof bags sell to everyone with a car; basket bags sell to the subset of people who already own a hitch carrier. So the product category is roof bags, and basket use is an off-label application that the manufacturers neither design for nor forbid.
The practical consequences, so you can shop around them:
| Designed for a roof | What happens in a basket | What to do about it |
|---|---|---|
| Door-hook or rack-clip straps | Nothing to hook or clip to | Ignore them; strap through the basket mesh with cam straps |
| Full-size roof footprint | Overhangs a 20-inch basket floor | Buy mid-size, or accept the overhang and strap it down hard |
| Upward-facing zip | Collects water in the one place you do not want it | Look for a flap over the zip, or face the zip forward |
| Clean-air mounting assumption | Sits in rear-wheel spray instead | Expect dirt; choose a dark fabric and a rinseable finish |
None of this makes it a bad idea. A bag in a basket is cheaper, lower and less draggy than a box on the roof, and it is the most common real setup on the road. It is just worth knowing that you are adapting a product rather than buying one.
How to strap a bag into a basket
This is where people lose bags, so it is worth doing in order.
- Pack the bag full. A soft bag only holds its shape when it is full. A half-empty bag flaps, chafes and lets water find the seams.
- Put it in the basket, not on it. The basket floor takes the load and the walls stop lateral movement. A bag perched on the rails is relying entirely on straps.
- Two straps across, through the mesh. Cam straps, not ratchets — a ratchet will crush a soft bag and the fabric does not need that much tension. The cam strap picks are the right tool.
- One strap fore-and-aft. Across holds it down; fore-and-aft stops it migrating backward under braking. Both.
- Net over the top. Belt and braces, and it catches anything that works its way out of a zip.
- Twist the strap tails. A loose tail at 70 mph makes a noise you will hear for four hours and can whip paint. Twist them and tuck them.

Bag in a basket, or box on the roof?
Worth asking honestly, because the two setups cost about the same and behave completely differently.
A bag in a hitch basket wins on fuel — it sits in the vehicle’s wake rather than in clean air above it, and published testing on rooftop carriers finds a double-digit percentage penalty at highway speed. It wins on loading, at waist height instead of over your head. And it wins on storage, because a bag folds into a cupboard.
A box on the roof wins on security — a locked shell versus a zip — on weather, because a hard shell does not care, and on ground clearance, because nothing is hanging off the back. Our box versus bag guide and roof-or-hitch guide work through the decision.
The security point deserves emphasis here. A bag in a basket is a zip and a strap away from anyone in a parking lot. Do not put anything in one that you would mind losing, and do not leave it loaded overnight at a motel. That is not a product flaw, it is the nature of fabric.
