This beautiful rolltop backpack is made in Ashleigh's studio in Cornwall, and is the perfect companion to all your adventures. Martha loves hers for a morning sea swim or a stroll through the city with a coffee. The stunning silk and corduroy lining is the loveliest surprise every time you open it up.   Size: This pack fits a 15'' laptop nicely, and the rolltop allows you to adjust capacity depending on the day and the activity! How it's made:The canvas used in these satchels, backpacks and totes is a 14oz Duck Canvas. Duck Canvas has been used for centuries in the sea faring trades for it tough quality and its naturally water resistant properties. The canvas has been proofed to add extra water resistant qualities so raindrops will bead on the canvas surface, however if the fabric gets totally dunked in water for a time it will allow seepage. The waxed cotton used is made in a stunning old factory in Scotland. It is a beautiful fabric that takes on wear and truly does get better with age. The straps on these bags are made from heavy weight 100% cotton webbing. The fittings, such as the D rings, the loops and slides for adjustability of the straps, are all made from extremely durable solid Cast Brass.
