The Hapro Softbox is a great solution if you don’t have enough space to store a traditional roof box. It is constructed from a strong material with a rigid plastic base.

It’s easy to fold up and an internal frame gives you 375 litres of additional storage. This frame makes the box really easy to load and also keeps the softbag rigid when you are driving. Unlike other flexible roof boxes, the Softbox allows you to drive without load as well.

Opening and closing the Softbag is really easy as well. Both sides zip down allowing you to mount, load and unload the box from either side of the car. It also includes two mesh storage compartments to keep smaller items safe.

The Softbag folds flat (108 x 85 x 8cm) and includes a robust storage bag (folded dimension in the bag: 117x15x45cm). This is a really useful size, e.g. if you want to store it underneath a bed, or fit it into your loft.

Delivery FAQs

When will my order arrive?
There are no deliveries on Saturdays, Sundays or Bank Holidays, except for postable items where Royal Mail has a Saturday delivery. Express Delivery orders placed on a Friday (before 1pm) should be delivered on the Monday or Tuesday, Express Delivery orders placed on a Saturday or Sunday should be delivered on the Tuesday or Wednesday. The arrangements for Very Heavy Items are different and are shown above.

What about Next Working Day delivery?
We have offered a reliable Next Working Day service for well over 20 years but, due to the pressure on the couriers caused by the coronavirus crisis and the huge increase in online shopping, we can no longer be confident about the delivery date, which is why we now call the service ‘Express delivery’. Most Express delivery orders will arrive on the next or second working day, but some will arrive on the second or third working day, or be split between these days. So-called “split deliveries” happen when the couriers do not have enough trailer space for everything that should be moved around the UK, so they will load what they can and leave the rest for the next trailer.

Is my delivery day guaranteed?
No retailer or courier company can ever "guarantee" a Next Working Day delivery. As well as split deliveries, all courier companies occasionally have the same transport problems as can happen to everyone else, including snow blocked roads, closed roads, traffic jams, mechanical breakdown, an inability to find the delivery address, or to gain access to it if, for example, it's in a block of flats. We work with some of the best couriers in the business, and overall they provide an outstanding service.

Do I need to be at home?
We are very flexible with our deliveries and will aim to deliver to an address which suits you – this does not need to be your home address. Goods can usually be left without signature - we prefer this with roof boxes. There's a "Special Delivery Instructions" box in the checkout area where we'll ask you to choose a typical instruction and then amend it to suit your particular requirements.
