Waxed Cotton motorcycle jackets were some of the very earliest motorcycle jackets, from companies like Barbour and Belstaff, were made from wax cotton. Initially they were used by sailors. Today, wax cotton is very much in fashion, but it’s also very practical. A wax cotton motorcycle jacket does not easily absorb moisture. In fact, rain tends to run off it. But if you combine a wax cotton outer with a waterproof membrane, you can end up with a very high level of waterproofing. But practical as wax cotton can be as a material for a motorcycle jacket, its popularity is linked to its classic heritage. Today, the best of wax cotton jackets are, without doubt, Belstaff jackets. They make the best. You can wear wax cotton jacket on a classic bike, on a modern retro, a custom bike, or indeed any kind of naked motorcycle. McGregor and Boorman also made wax cotton very popular with adventure bike riders. Wax cotton makes for a great jacket that you can wear all year round.
