Impregnation with impregnation spray:
Impregnation protects your bag from moisture and dirt without affecting its appearance - so it stays weatherproof and elegant.
You may use the colorless waterproofing spray from market, which forms an invisible protective layer and protects both leather and cotton.
It is best to use the spray outdoors in a place protected from the wind. Spray it evenly onto the clean, dry bag from a distance of about 30 cm.
Be careful not to soak the material and let it dry thoroughly. You can protect stressed areas such as edges with a second layer. The bags in the Heritage collection made of waxed canvas do not need to be additionally impregnated.
