How Helly Tech® works

How Helly Tech works
  1. DWR treated water-repellent outer fabric
  2. Waterproof and breathable membrane or coating
  3. Highly breathable inner fabric, mesh or lining

3 performance levels

professional-graphic

Extremely waterproof and breathable designs and constructions tailored to the needs of professionals. For highly aerobic, extremely wet or unusually long-lasting activities in extremely harsh conditions.

performance-graphic

Highly waterproof and extra breathable sport specific designs and constructions. For a wide range of high performance outdoor activities during highly challenging, changing and unpredictable weather conditions.

protection-graphic

Fully waterproof, windproof and breathable fabrics and constructions. For all situations and weather conditions where protection from the elements is needed.

When facing the elements, you need complete confidence in your gear. Helly Tech® Professional state-of-the-art waterproof and breathable technology provides the ultimate protection from the elements. Helly Hansen is worn and trusted by more then 30,000 professional sailors, mountain guides, ski patrollers, instructors and mountain safety personnel around the world.

Waterproofness and breathability ratings typically above 20.000 mm and 20.000 g/24h/m2 respectively.

For any outdoor activity where performance is key and water contact inevitable, the Helly Tech® Performance layer is your technical barrier against the elements. The waterproof and breathable technology moves water away from the body, keeping you dry and warm, and allowing you to perform your best.

Waterproofness and breathability ratings in the range of 10.000-20.000 and typically around 15.000 mm and 15.000 g/24h/m2 respectively.

For all activities in wet, cold and windy weather Helly Tech® protection is the ideal protective layer. The guaranteed waterproof and breathable technology stops water going in, but also moves moisture out, meaning you stay dry and warm regardless of the conditions.

Minimum 5.000 mm waterproofness and 5.000 g/24h/m2 breathability and typically in the range of 5.000-15.000 for both respectively.

Fully waterproof , windproof and breathable Helly Tech® certified fabrics. Critically seam taped construction. For cold, dry and less severe wet weather conditions when only light protection is needed.

Minimum 5.000mm waterproofness and 5.000 g/24h/m2 breathability. Critically seam sealed.

DWR

Durable Water Repellent

All Helly Tech fabrics are treated with a durable water repellent treatment to prevent any dampness seeping through. This lowers the surface tension of the fabric to ensure water beads on the outer layer of fabric, leaving you dry and comfortable.

Ply technologies

Helly Tech® is engineered by Helly Hansen’s fabric development team and is based on multiple technolgies.

Manufacturing technologies

Lab tests

All Helly Tech® are tested by accredited third party textile laboratories ensuring accurate and objective test data.

WATER COLUMN

  • ISO 811 and JIS LIS L1092-B1

  • Gives the value of pressure mm of water held back by the fabric – 10000 mm is the same pressure you would experience diving to 10m or equal to the pressure from a fire hose.

BREATHABILITY

  • JIS L 1099-1985-B1

  • Gives the value of g/m2/24h – the amount of water molecules that can pass through 1 square meter of fabric within 24 hours.
  • 15.000 grams breathability equals that a jacket is able to pass 30 liters water in 24 hours. In comparison, our human body perspires 1 liter per 24 hours but can perspire as much as 3 liters per hour in warm humid conditions and extreme activity.

WATER REPELLENCE

  • ISO 4920:1981 and AATCC 35-2006

  • Spray test: testing of the durable water repellence before and after washing, by drizzling the fabric and measure how many drops that bounce up and if any attaches or wets out the fabric surface.
  • High score in water repellence means the water drops will shed like water on a duck.
