Technology and materials glossary

At Kathmandu, we use a wide range of advanced technologies and ground-breaking materials in our outdoor products. You’ll find this comprehensive glossary organised alphabetically for your ease of use.

Bionic DPX

Durable Bionic™ DPX™ fabric addresses ocean plastic pollution in marine and coastal environments. It’s created from recovered ocean plastic which is:

  • Collected and chopped up
  • Melted down
  • Spun into yarn
  • Woven into an eco-friendly fabric

Combining recovered plastic material with other fibres means Bionic can develop a variety of textiles – one of which is DPX.

Find out more about Bionic DPX.

Our driMOTION fabric technology is designed to:

  • Wick moisture
  • Dry quickly
  • Keep you feeling cool, fresh and comfortable

Stay actively comfy when the heat is on.


A pioneer of textile technology, drirelease™ is part of the best performance fabrics and activewear in today’s marketplace. It’s what helps you move more comfortably – by wicking, drying, cooling and freshening.

drirelease pulls moisture away from your skin and dries fast. We’ve integrated it into a bunch of our travel and adaptable garments. In fact we have some history here, having won drirelease’s Summer 2017 Innovation Award.

Find out more about drirelease.

drirelease E.C.O. (Environmentally Correct Origins)

An eco-friendly version of drirelease™ – E.C.O. – also pulls moisture away from your skin and dries fast. It won’t wash out, diminish over time or release harmful chemicals into the environment.

Find out more about drirelease E.C.O.

Durable Water Repellency (DWR)

Almost all our rainwear is treated with a Durable Water Repellent (DWR) finish. DWR encourages water to bead off the surface of your fabric, preventing precipitation from soaking it.

DWR does become less effective over time – due to dirt, abrasion, body oil and washing. However, you can revive your jacket’s performance easily at home.

Find out how to maintain DWR on your jacket.


EarthColors™ dyes are made from natural waste materials that can be traced back to their source – both their location and the type of waste. They’re a more environmentally friendly way of dying clothing.

We’re excited to be utilising these high performing, revolutionary dyes that are made from non-edible agricultural waste.

Find out more about our Earthcolours Range.


ECONYL is a nylon that’s 100 percent regenerated.

Aiming for no waste and no new resources, ECONYL’s regenerated nylon comes from landfill and ocean waste. It’s indefinitely recyclable making it a closed loop regeneration process.

Find out more about ECONYL.


Ecoya fabric is created through an eco-dyeing process that adds colouration at the raw material stage, rather than traditionally at the yarn phase.

As a result, there are many benefits to creating Ecoya fabric. It:

  • Saves water
  • Uses less energy and fewer chemicals
  • Has reduced CO2 emissions
  • Gives a more colourfast fabric that stands up better to light, water and washing

Find out more about Ecoya.


Freshguard™ is a moisture transport and odour elimination technology that helps control odour. You’ll stink less and be able to wash your Freshguard clothing less often.


GORE-TEX® does a superb job protecting you against wind and rain. It’s a membrane that doesn’t let water molecules get through but allows moisture vapour and sweat to get out via the membrane’s microscopic gaps.

GORE-TEX offers you three core benefits. It’s:

  • Waterproof – even in the heaviest storms, rain and snow can’t get through
  • Breathable – water vapour can escape so you’ll stay cool when sweating
  • Windproof – able to block out wind and keep the cold at bay

You can be sure of maximum protection even in the harshest conditions.

Find out more about Meryl Skinlife.

Moisture Control System

Moisture Control System (MCS™) is essentially a wicking finish on some of our synthetic fabrics that:

  • Absorbs and wicks moisture away from your skin
  • Releases this moisture on the fabric’s surface so it evaporates quickly
  • Helps keep you cool, dry and comfortable

No Fly Zone

Our buzzGUARD range uses fabric containing an effective, long-lasting treatment called No Fly Zone™ that repels mozzies, ticks, flies, ants and midges.

No Fly Zone is an odourless, Permethrin-based technology that causes these insects to fly away without biting. It’s designed to hold onto the fabric and be effective for at least 70 washes – essentially the expected lifetime of your product.

Find out more about No Fly Zone and buzzGUARD in this Summit Club Member Review video.

RFIDtech (Radio Frequency Identification)

If you decide to keep your valuables on your body, you may want the added security of RFID blocking accessories to help prevent digital theft. RFIDtech will help keep your passport and credit card information safe.

RFIDtech is used as a wireless way of transmitting information from a chip to a scanner (or reader). An RFID scanner needs to be in close proximity to a chip in order to read its radio waves.

Whether RFIDtech is hidden in a pouch, belt bag, travel wallet or a safe pocket in your clothes, it can be your extra barrier of protection.

Find out more about RFIDtech.

Thermore Ecodown

Ecodown™ is a synthetic insulation that can keep you warm, even in damp conditions – and Thermore™ is a leading player in the field.

Compared to traditional down, a jacket with synthetic fill has some significant advantages, such as:

  • Keeping you insulated, even in slightly damp conditions
  • Not clumping or getting cold spots after being washed
  • Fast drying times

Find out more about Thermore Ecodown.

Ultraviolet Protection Factor (UPF)

Some of our clothing carries a UPF rating which indicates how well it protects against the sun’s harmful effects, such as blocking solar ultraviolet radiation (UVR).

The higher a garment’s UPF rating, the more solar UVR is blocked by the fabric – and the less solar UVR exposure to your body.

We test our fabrics and give them a UPF rating if they have sun protection qualities. For instance:

  • UPF 30 is defined as good protection
  • UPF 50+ is defined as excellent protection

Ultraviolet Protection Effectiveness (UVE)

Some of our beach equipment carries a UVE rating which indicates how well it reflects (or absorbs) solar ultraviolet radiation (UVR) to protect against the sun’s harmful effects.

We test our shade, shelter and beach umbrella fabrics in an accredited lab to determine their UVE rating. For instance:

  • 80-90.9% UVE is defined as effective
  • 91-94.9% UVE is defined as very effective
  • 95+% UVE is defined as most effective

A number of variables need to be taken into account when considering the effective sun protection of beach equipment, such as size, position, sun angle and nearby reflective materials.

Shade, shelter and beach umbrellas provide you with shade ‘at a distance’ – so we can’t test them to Ultraviolet Protection Factor (UPF) ratings as these are only applicable for next-to-skin clothing.


The Woolmark™ brand is the global authority on wool – it works alongside Australian woolgrowers to research, develop and certify Australian wool.

Woolmark is a commitment between woolgrowers, brands and consumers on the authenticity and quality of the wool. When you see products bearing the iconic Woolmark logo, you can trust that the wool has quality, is authentic and offers value.

Find out more about Woolmark certification.
