We received our new MSR Mutha Hubba Tent in the mail on Wednesday so we decided to camp out Wednesday night to give it a test. It was extremely easy to set up and only took a few minutes.
As for space, I am 6ft 3″ and there is more than enough room for me, I can even sit up without incident. Also the entire tent only weighs 7lb or 3.3kg perfect for hiking.
