Best roof boxes for winter 2025 – Why a back box is the smarter choice 

When planning ski trips or winter holidays in 2025, many drivers search for the best roof boxes. Roof boxes remain a classic solution – but they also come with limitations that become even more noticeable in cold, snowy conditions.

The downsides of roof boxes in winter

• Hard to load: Lifting skis, snowboards, or luggage overhead on icy ground is inconvenient and unsafe.

• Reduced efficiency: Roof boxes increase drag by up to 40%, cutting EV range or raising fuel costs on long winter drives.

• Extra noise: Turbulence from a roof box makes long journeys noisier and less comfortable.

• Stability issues: Added weight on top reduces handling and safety in winter weather.

The smarter alternative: back boxes

Towbar mounted back boxes like IXTAbox solve these problems with smarter design:

• Up to 390 liters of storage – fitting skis, snowboards, and bulky winter gear.

• Waist-height access – safe, quick loading without climbing.

• Aerodynamic advantage – positioned at the rear, reducing drag by up to 5%.

• Scandinavian craftsmanship – built in Sweden to handle snow, ice, and road salt.

👉 For winter 2025, the best “roof box” isn’t on the roof at all. It’s a back box – and IXTAbox is the market leader.
