Extended Product Information

FAQs

Is this jacket waterproof?

It is highly water-repellent thanks to the 6oz. British Millerian waxed cotton finish, making it excellent for rain and wind.

Can I wash the Belstaff Sideline jacket in a washing machine?

No. Machine washing will remove the wax treatment and damage the fabric. Spot clean only.

What is the material composition?

The outer shell is 6oz. British Millerian waxed cotton, and the interior is lined with cotton twill.

Does the jacket fit true to size?

The jacket follows standard sizing, though the waxed cotton construction may feel more structured compared to standard denim or leather.

Can I wear this jacket in the summer?

It is best suited for transitional weather or cooler temperatures. It may feel too warm during peak summer months.

How should I store the jacket?

Hang it on a wide, sturdy hanger in a cool, dry place with good air circulation.

Troubleshooting

Jacket feels stiff upon arrival

Waxed cotton naturally softens with use and body heat; wear the jacket regularly to help it conform to your body shape.

Small dirt spots on exterior

Use a soft brush or a damp sponge with cold water to gently remove dirt. Do not use soap or detergent.

Wax finish seems to be thinning

If the jacket loses its water-repellent properties, apply a standard waxed cotton re-proofing treatment specifically designed for British Millerian fabrics.

Setup, Compatibility & Care

Because of the waxed cotton construction, this jacket does not require 'setup' but does require intentional care. To maintain the jacket's weather-repellent integrity, avoid machine washing or dry cleaning, as these methods can strip away the protective wax. Instead, spot clean with cold water and a soft brush as needed. Over time, as the wax layer thins due to wear, you may need to re-wax the cotton fabric using a professional-grade wax dressing. Store the jacket in a cool, well-ventilated area away from direct heat sources to prevent the wax from melting or transferring to other surfaces.
