Correspondingly, when I was offered the opportunity to test out the TETON Sports Mountain Ultra 1 a few months ago, I was slightly concerned. The Mountain Ultra 1 was billed as an ultralight backpacking tent; and in my experience, such products were not durable; or not breathable. Nevertheless, I was intrigued as to what innovations TETON had brought to the field as there had been a lot of social media buzz about the tent, so with an open mind I accepted the tent and began the testing process. Several months later, what I can say is this: this is a product that lives up to the hype it generated, and then some. Even further, I can honestly say that this tent is the best one-man backpacking tent on the market in 2014; and perhaps the best one-man backpacking tent that I have used in the last five years.
