Constructed in a three pole tunnel design, the Vango Pulsar Pro 200 has been upgraded for 2018 and now has a fully waterproofed, taped seamed, rip stop nylon flysheet and light, high quality alloy poles designed in a Gothic Arch Structure to assist water and snow run off and stop the tent going sideways in rough, windy conditions. Combined with Vango's Tension ii Band System, this tent is incredibly strong and stable for hill and mountain use. There is a descent amount of storage room which is essential if you are doing activities involving a fair amount of kit and the ventilation is good too, providing plenty of fresh air and less condensation in the morning. An oversized compression bag makes life so much easier to get the tent in and out quickly, especially when it's pouring down. See below for the Pulsar's excellent features...its a long list!
