Quick answer

For most Tesla owners, the X-Rack Waterproof Medium Cargo Bag offers the best balance of capacity and trunk-well fit. Choose the Mini for short trips or tight spaces, and the Slip Cover Bag when you need to protect irregular luggage on a cargo carrier.

Why size matters for your EV

Tesla trunks and roof racks have specific dimensions. A bag that fits the trunk well of a Model X may not work on a hitch carrier or a roof rack. X-Rack bags are designed with these constraints in mind, so matching the bag to your carrying method is the first decision.

All three bags are waterproof, but they differ in how they attach and what they carry. The Medium and Mini bags fit two side-by-side in the Model X trunk well and also work on X-Rack carriers. The Slip Cover Bag is a different concept: it goes over already-strapped cargo rather than being a standalone bag.

Trade-offs to consider

The Medium bag (USD 58.49) gives you the most storage for its footprint, but it requires tie-down straps (not included) when used on a carrier. The Mini bag (USD 39.59) is lighter and cheaper, but its smaller size may not hold enough for a multi-day trip. Neither bag includes straps, so factor that cost into your decision.

The Slip Cover Bag (USD 62.99) is the most expensive option and does not function as a standalone bag. It is a cover that fits over cargo you have already strapped to a carrier. If you travel with odd-shaped luggage or gear, it is worth the extra cost. If you prefer a self-contained bag, stick with the Medium or Mini.

Decision rules

  • Use the Medium bag when: You need the most capacity for a weekend trip and plan to use it in the trunk well or on an X-Rack carrier. It fits two side-by-side in a Model X trunk well.
  • Use the Mini bag when: You want a lighter, cheaper option for day trips or limited space. It also fits two side-by-side in the trunk well and works on X-Rack carriers.
  • Use the Slip Cover Bag when: You already have luggage or gear that you will strap to a cargo carrier and need waterproof protection. It is not a standalone bag. Remember to buy tie-down straps separately for any bag used on a carrier.
