I have used it on one trip per year every September for leaf viewing season in Colorado for less than a week each year. The YKK zipper functions beautifully. I ALWAYS showered before getting into this bag and I used a silk liner EVERY single time. I closely inspected this bag inside and out, and there are no cuts, holes, stains, rips, seams coming loose, smells, etc. Anywhere to be found. There is one very small stain on the bag as you can see in the photo. The original green bag is included, which I always used to store the bag when it was not in use. The picture of the loft does not do it justice due to the angles, but the loft, when EVENLY laid out flat, measures between 6.5 and 7. I would say closer to 7, which was its loft when it was brand new. Always stored in a 100% nonsmoking home. Thanks for looking, and get a great deal on this very nice bag!
