We love the look, feel and performance of this high-quality waxed sailcloth. It is water-proof, and looks like leather when it gets worn. We have both 7 oz. and 6.25 oz. waxed cotton. The heavier version is great for bags, such as the Right-to-Roam Rucksack. The lighter version is also great for bags, and also a Landgate or Kelly Anorak rain jacket.
