I havent hiked with it yet but have seam sealed it and tweaked the guy lines with gear in the tent. This Has eliminated the wrinkles you see in the photos. I received my G4 pack kit from Quest outfitters a couple days ago. I plan to make three packs from the pattern . One will be for me and the other two for my son and girl friend. They are interested in hiking so i want to encourage them. My G4 will be made fro 1.1 oz a yard silnylon. Hoping for ten to eleven ounce total pack weight? I will post
