The Best Cargo Boxes for Skis and Snowboards

Measure the skis, not the family. The relevant number is the longest pair that will travel, and the box needs internal length beyond that for bindings and for the taper that every molded shell has at both ends.

Makers publish an internal length for exactly this reason. If a listing gives you only external dimensions, treat that as a reason to check the manufacturer’s own site before buying.

Boards are short enough for most boxes and wide enough to be awkward in a narrow one. The floor width at the widest point is the number that matters, and a long narrow box optimized for skis can be the wrong choice for two boards side by side.

If the trip is boards rather than skis, a wider box is better, and the trade-off against bar space goes the other way. A mixed load of skis and boards usually ends up in the biggest box that still fits the roof.

Whatever goes in, pack it so it cannot move. A loose board sliding lengthwise inside a shell at highway speed is both a noise and a loading problem, and our cargo box loading guide covers how to stop it.

Ski trips are winter trips, which means three things that do not apply in July. Salt and grit will coat the box and the bars; wash both when you wash the car, and especially the clamp area, where corrosion costs you a box. Locks freeze; a shot of a dry lubricant before the season saves standing in a car park with a wet glove and a dead key. And the roof will be snow-covered when you come back to the car, so clear the box lid before opening it or the snow goes inside.

The drag penalty is also worse in winter. Cold dense air costs more to push aside than warm air, on top of whatever the box itself costs — and a mountain drive is mostly highway. If the fuel number matters to you, the figures are in the gas mileage guide.

Finally, leave the box empty and the bars off between ski weekends if you can. There is no reason to carry either through a month of commuting.

A hard box is the correct answer for skis and the only one we would recommend without reservation. Skis are long, expensive, edged and unhappy about road salt, and a shell protects them from all four problems while locking.

A soft bag will carry skis in the sense that they fit. It will not keep edges away from fabric, it will not lock, and it will not keep slush out indefinitely. We compare the two properly in cargo box vs cargo bag.

An open basket is the wrong tool entirely for skis: no weather protection, no security and a lot of noise. Baskets earn their place with bulky, dirty, awkward loads instead — that comparison is in cargo box vs roof basket.
