Care and repairs
How should I care for my leather backpack?
Treat with wax every 4-6 months or when the leather feels like it's drying, treat lightly with wax. Wipe the leather to clean it. With a cloth spread a thin layer of wax on the leather. Allow the wax to permeate overnight and then polish the remainders off with a cotton or wool cloth. The scent of tar will fade away in a couple of days, if a lot of wax is applied, this will take longer.
We recommend using natural products like bees wax based products or natural oils. Synthetic leather protection can block the pores of the leather. This will reduce the leather's ability to absorb wax and oils - ultimately reducing the lifespan of the backpack.
How long is the break-in period of the leather backpack?
Like all high-quality leather goods, Kasperi backpacks also have a break-in period. It will take a couple of weeks of active use for the shoulder straps to start forming to your body. If you experience any pressure points, squeeze the straps lightly with your hands from the pressure points to help it form faster.
Closing and opening the G-buckles is also stiff at first but as the leather loops softens and form over time it will become fluid.
With proper care and use, these packs develop a unique patina and become more personal by the day.
What about repairs?
The hardest-wearing parts (i.e. shoulder straps) are made from 3mm leather for longevity and the whole structure is designed with serviceability in mind.
We offer a repair service for our bags and backpacks.
