Between 2023 and 2025, before   researching fabrics focused on research.

We studied down insulation across different regions, suppliers and industry standards worldwide. This research became the foundation of our approach, because down is the core of our winter puffer vests.

Our goal from the beginning was simple: to understand how down works in real conditions - how it retains warmth, how it breathes, how it feels during everyday wear and how it performs over time.

Down is not just a material.It defines the comfort, warmth and overall experience of a winter vest.

That is why we spent years comparing different types of down, reviewing technical data, supplier documentation and certification requirements, before making any sourcing decisions.

Only after this process did we move forward.

Certified European Down

   Our winter Puffer vests are insulated with certified European down . The down is carefully cleaned , purity and stable performance. Certification confirms that the material meets industry requirements related to sourcing, processing and quality control.

This allows us to work with down we trust.

We use 700 Fill Power down in our puffer vests.

Fill Power measures the ability of down to trap air and recover its volume after compression. The more air the down holds, the better it insulates.

700 Fill Power provides  reliable warmth , light and comfortable wear , 

Our insulation consists of mostly natural down, with a small percentage of very fine feathers.

This composition helps maintain softness and flexibility, while supporting the structure and durability of the insulation over time.

You will feel the difference.

We continuously follow innovations in down processing and insulation technology.

The down industry evolves - from improved cleaning methods to better sorting techniques and performance testing. It is about improving how a product feels and works.

       Down is a natural, living material.It breathes, adapts to body temperature and creates a balanced microclimate inside the vest.

This is not something you only read in specifications.

It is something you experience while wearing the product.

Comfort that stays consistent.

Built around down

Georgian Streets is built from the inside - because when the core is right, everything else follows.
