I just wanted to give an update on the Wingnut Hyper Pack. I’ve had the Wingnut pack now for about 10 months. It is still going strong. I’ve had no problems with fatigue from the pack and the light sailcloth material is proving to be more durable than I thought it would be. The zippers are still working properly and I am loving how light this thing is. It can hold quite a bit of gear and sits just right on your back. The only problem that I’ve had with the pack is that if you don’t wash it regularly it will stink to high heaven. So you don’t want to go too many rides without washing it, and if you don’t get a chance to wash don’t leave it in your vehicle in the hot summer sun. Just a little word of caution. Overall I am very happy with the performance and comfort of the Wingnut Hyper Pack.
