It is an old model or a product that we can no longer order at the manufacturer.
This tent is amazing. Its structurally super strong and the material is a very high quality and quite thick. Ideal for both cold and stormy weather. Sleeping in the tent is very comfortable. Ample room for 3 people or 2 people with full kit. The inner tent is very good quality and is perfect for the 6ft ish person. Anyone above this may struggle as i was couple of inches off head and foot lying down. Apart from that i highly recommend this tent. And its a name that should be well known because they spare no expense on quality. Hopefully this info helps you secure your purchase as i am super happy.
