The Superlight Quasar uses new ultra light double silicon fabric which retains excellent durability & waterproofing The geodesic consruction makes this a very ridgid tent weighing in at just 1 25kg per person The success of our Superlite Voyager has spurred us on to create superlite versions of our most successful models These should be firm favourites with those who value the benefits of a geodesic structure yet want to keep weight to a minimum guarantee This Terra Nova product is guaranteed to the original owner against defects in materials & workmanship for the lifetime of the product Please note however that due to the super light nature of the material used in the tents construction we are unable to factory seal the seams in a conventional method However they are positioned & sewn in a way that minimises water penetration & it is possible to add further protection yourself with seam sealer to fully waterproof the tent
