Yes — in independent abrasion testing, hemp canvas outlasts cotton duck canvas of the same weight by a factor of 2–3×. Our standard backpack hemp is 12 oz/yd² (similar to military canvas), double-stitched at stress points, with YKK or equivalent zippers and reinforced webbing straps rated to 15 kg. We have buyers reordering the same backpack model for school programs where kids use them daily for 3+ years.
