Frustrating to me is that I sew and am perfectly capable of replacing a zipper if I only could purchase a replacement zipper! Hard to find such. All my zippers break at the curve in the zipper. Old tents used two straight zippers lasted longer. Two zippers also broke on my pack on my most recent trip. Both gaiter straps broke. Got two more holes in my hiking pants. I was hoping to get one more season from my old gear.
