WU1-1 Inverted Helmet Bag - Treated Grey

This inverted Helmet Bag has a Ventile inner and outer shell – a natural material invented for transatlantic air force pilots during World War II. Breathable and able to repel water, this natural unwaxed material is designed to last a lifetime.

The WU1-1 features a removable crossbody strap, two large interior pockets and a separate laptop compartment.

The bags are handcrafted in very limited quantities in The Netherlands and given a special treatment by hand at our studio in Amsterdam, making each bag unique.
