Vango Equinox 350:

 An obvious choice for the all-round adventurer, the Equinox 350 is lightweight, has generous storage and sleeping areas and is versatile, robust and comfortable.

The tunnel-style construction means it's very roomy and the huge storage area has plenty of room for bikes, gear or furniture. The TBS 'Tension Band System' and pole sleeve tension adjustment ensure that your tent stays stable in the worst weather.
 
The seam-taped flysheet is constructed from highly durable Protex 70D SPU-RP (silicone coated ripstop polyester), and the groundsheet is HD nylon with a 5000 HH rating (VERY waterproof), so you'll be completely protected from any adverse weather conditions.
 
The inner is breathable, and the various options for mesh doors and vents mean that you'll be comfortable inside whatever the conditions. O-shaped doors mean one-handed operation to open or close.
 
You also have the 3-in-1 options of just using the footprint and flysheet for convenience in easier conditions, or fly, inner and groundsheet for more comfort.
 
Great for campers on the move, who need a solid base camp, or a stable portable home.
