How is the 'duck canvas' mentioned in the pants description different from regular cotton fabric?

While looking through ostrya's Botwood Cargo Shorts Khaki, you will encounter the unfamiliar name 'duck canvas' in the material guide. Duck Canvas has nothing to do with the bird duck, and originates from the Dutch word doek, meaning thick linen or cloth. Whereas conventional cotton fabric weaves a single strand of yarn to bring out softness, duck canvas twists two or more strands of yarn and tightly weaves them in a plain weave without gaps. Because the density between yarns is very high, it blocks wind well and possesses toughness so that it does not fray or tear easily even when scratched by rough objects.

ostrya finished these shorts with 100% cotton duck canvas material^[1][2]. Its ability to withstand friction and abrasion is excellent, reducing damage to the fabric even during outdoor activities passing through rocks or bushes^[3].

hmmm, in choosing a natural cotton fabric that feels heavy in hand instead of light and smooth synthetic fibers, a solid attitude conveys the hope that the clothing will not wear out easily even in harsh environments and will endure for a long time.
