Brompton Musette Bag
As Brompton say "Some things are better when they fold" and now that includes this new (for 2026) Musette bag
Available in a choice of two colours:
- Anthracite Black
- Copper
to suite your mood
Unfold the bag and throw it over your shoulder when plans change. Roll the top down and fasten it closed, or leave it open and use the side cinch straps when you’re carrying more.
It expands from 4 to 6 litres
It handles everything from an extra layer to a stop at the shops
Built from recycled nylon with a water-resistant finish, this bag is designed for regular use and to last!
Based on the classic bag used to provide on-the-go provisions to professional road cyclists, it’s a lightweight style with an adjustable crossbody strap. It has expandable storage (up to XXL) and includes a number of useful internal and external pockets to keep things organised. And for an extra touch of usefulness when not in use, it can be easily rolled up and attached to your seat post or saddle rails using the integrated strap.
