Having visited Northern Walkers blog to check out his latest purchase, he informed me that there was the possibility of a new version of the Golite Shangri-La 3 coming out next year. Intrigued, I contacted Golite directly and they confirmed it.
Apparently they are looking to release a lighter version of the SL3 in the spring. It will apparently weigh in at approximately just over 1kilo (inc pole and pegs) and have a larger vent. Also the current full inner will be lightened to around 800g. Unless my maths stink this represents around 500g saving on the full fat set up bring it in at around 1.8kg complete. Although by no means ultralight, this is a significant weight reduction for a popular 4 season tent (palace). Most of the weight saving will be through using lighter but stronger materials but what they will be was not revealed to me.
