Used materials

Duck down
600 cuin, 90/10 down

One of the best natural insulators is duck down feathers. It's what we use to fill Hill jackets with 650 Cuin. The down is mixed with small feathers in a 90/10 ratio - this is because the small feathers are flexible and help maintain the shape of the chambers and the fluffiness of the material.

Nylon Ultralight DWR
Very light and sturdy nylon txtile with DWR waterresistant modification
Polyester Ultra-Lite
Soft and lightweight polyester fabric
is a fabric manufacturing technology designed to increase resistance to mechanical damage while maintaining weight

At regular intervals, thicker fibers forming a grid are woven transversely and longitudinally into the tropic material, thereby preventing further crack propagation if the fabric is torn.

Better performance of down and feathers
Down is one of the best insulating materials for jackets and sleeping bags, thanks to its excellent warmth-to-weight ratio and resistance to pressure damage. These properties work even better when the feathers are treated with Teflon™.
Teflon™ prevents the down filling from absorbing moisture from the environment. This allows the feathers to retain their insulating properties while resisting compression damage.
Feather properties after Teflon treatment:

  • Drying faster
  • Keeping warm and fluffy
  • After washing, it regains its original loft (fluffiness) more easily and quickly

Feather Processing

The RDS (Responsible Down Standard) aims to ensure that the down used comes from animals that have not been subjected to unnecessary injury and stress.
This is achieved by independent certification bodies that audit all stages of the supply chain.
Any removal of down and feathers from live birds (plucking live birds) is prohibited; forced overfeeding is also prohibited.
Certification ensures that RDS standards are followed and maintained throughout the supply chain; from the farm to the final product.

Climate Control Shield

ClimaControl Shield technology provides a balanced outer fabric, prevents the escape of warm air from the inside and at the same time ensures adequate breathability.
It optimizes the ratio between windproofness to retain warmth and internal moisture ventilation to prevent condensation.
The combination of these properties ensures user comfort and a favorable internal climate of the sleeping bag.
The water-repellent treatment provides sufficient protection against adverse weather effects.
Fabric with Clima Control Shield  it is light, packable and soft to the touch.
