I purchased your 16.5x16" Pack liner when it was on sale last week and I was blow away by the quality when it arrived yesterday. It was exactly the size I was looking for to slip inside my MLD Burn pack. This is the only item of cuben that I own, however I immediately took note of the quality taped seams, attention to details in the folded bottom corners, and no errors in the construction from what my eyes could see. The buckle for the closure appears very durable and well incorporated. A+. I'll be looking to pick up a stuff sac in the future. I've yet to take it out and use it, but will definitely be putting the old plastic packliner in the closet.
