Halo British Downhill Series – Pop up Shelter Supplier Surf & Turf Instant shelters are the preferred pop up shelter supplier to the majority of riders in the Halo BDS paddock. We recently attended the the second round and managed to get some great shots of various shelters we have produced, for riders, shops and teams. A Surf & Turf Pop Up Shelter will act as an ideal pit awning, ensuring you stand out, look professional and most importantly provide you with protection from the elements when at the races.
