Coastal-inspired colour, minimalist design and everyday convenience. The ROKA Chelsea B North Sea Recycled Nylon Bag combines a compact crossbody silhouette with the practical organisation that makes the Chelsea collection ideal for travelling light.
Designed for carrying your phone, cards, keys and smaller essentials, this slim sling bag offers an alternative to traditional handbags and larger backpacks.
The North Sea colourway introduces a distinctive blue-inspired shade, bringing a subtle coastal influence to everyday accessories. It works particularly well with cream knitwear, charcoal trousers, washed denim and understated casual clothing.
A front flat zipped pocket provides convenient storage for your phone, while a rear slip pocket and internal slip pocket help organise smaller belongings.

The Editor's Take
The ROKA Chelsea B North Sea is particularly appealing for customers who want a practical everyday accessory with a subtle alternative to traditional neutral colours.
Its compact silhouette keeps the design understated, while the North Sea shade introduces a distinctive coastal-inspired character.
The separate pocket arrangement is particularly useful for everyday organisation.
Rather than carrying everything in one compartment, the Chelsea B makes it easier to keep your phone and smaller belongings accessible.
Compared with ROKA's Puffy Taslon Chelsea B, this recycled nylon design offers a flatter, more streamlined silhouette.

Emma met Brett in 2014 while abroad with her family. After months of long-distance romancing, Brett moved to London to be closer to Emma.
Being from a country that is sunny nearly all year round, Brett took himself to Oxford Street in jeans and a t-shirt whilst the sun was shining, with his trusty notebook in an old backpack.
What started off as a sunny day ended in a typical British downpour with Brett coming home soaking wet. It wasn’t just Brett who was drenched – everything he had in his backpack was wet too! That day was the birth of Roka!
Brett realised he needed to design a functional, weather-resistant bag for everyone, every day, for every occasion.
Brett designed the first bag, making sure it was sleek, stylish and simplistic, ensuring that it had the right compartments for everything.
A bag that was comfortable to wear with weight distributed evenly, and handles to be able to carry it in a multitude of ways. Brett wanted these key features to work across a number of bag styles that could be easily recognisable and repeated. After spending months looking for eco-friendly and ethically made materials, Brett took to work establishing the coatings to ensure the bag had the exact finish he envisioned, that was water-resistant, kept its original colour, and looked and felt right.
Since then, the Bantry has gone on to be sold all over the world, in thousands of stores from USA to Sweden, and new products and styles have also been released using the original design system that Brett created.
