Invest in Montblanc's practical duffle bag if overnight and weekend trips are a prominent part of your schedule. Expertly made in Italy from croc-effect leather, it has a spacious interior fitted with many pockets to organise your belongings - you can use the lock and key to keep the most precious items secure. The zip pulls, handles and stitching are shaped like nibs, in tribute to the brand's history of crafting writing utensils.
