Product Information

Full details

The Stone Island Seamless Tunnel Down-TC Jacket is designed for the modern adult male seeking high-performance insulation combined with a sleek, technical aesthetic. Its primary benefit lies in the innovative seamless construction, which utilizes a specialized weaving technique to create down-retaining tunnels, drastically reducing leakage and cold spots. While it offers superior warmth and a unique dyed finish, users should note that the garment requires specific care due to the sensitive nature of the anti-drop treatment and the direct-injection down process.

Extended Product Information

FAQs

What is the Seamless Tunnel construction?

It is a specialized weaving process where the loom creates tubular channels in the fabric directly. This eliminates the need for sewing holes, which are usually the exit points for down feathers.

Is the jacket fully waterproof?

No, the jacket is finished with an anti-drop agent, making it water-resistant against light rain or snow, but it is not intended for heavy, sustained downpours.

Can I machine wash this jacket?

It is highly recommended to follow the care label specifically. Due to the garment-dyeing process and technical nylon construction, machine washing can cause damage or color loss.

What does RDS certified mean?

Responsible Down Standard (RDS) certification ensures that the down and feathers used come from animals that have not been subjected to unnecessary harm, such as live-plucking.

How should I store the jacket during summer?

Store it in a cool, dry place on a wide hanger. Avoid storing it in a vacuum-sealed bag, as compressing the down for long periods can damage its loft and insulating properties.

Troubleshooting

Small feathers appearing on the surface

This can happen occasionally with new down jackets. Gently pull the feather back into the tunnel from the inside of the jacket rather than pulling it through the fabric.

Water repellency seems to decrease

The anti-drop agent may wear off over time. You may need to have the garment professionally retreated with a textile-safe water-repellent spray.

Setup, Compatibility & Care

To ensure the longevity of your garment, adhere strictly to the care label inside the jacket. Because the jacket features a delicate anti-drop coating, it should not be dry cleaned using standard harsh solvents. Instead, spot clean when necessary with a damp, soft cloth. If a deeper cleaning is required, ensure it is handled by a professional cleaner experienced in handling technical sportswear and garment-dyed items to prevent the color from fading or the technical properties of the nylon from degrading. When storing, always use a wide, padded hanger to maintain the shape of the hood and shoulders, and avoid keeping the jacket in compressed storage for long durations, as this may affect the loft of the down.
