The Katmai combines the ultra-cooling and protective lightweight Parameta A fabric with travel friendly design features that help keep out insects, provide discreet pockets and allow freedom of movement. The Katmai provides protection and cooling in one easy care, very weight efficient shirt.


The Katmai offers design features that enhance the fabric protection, provide practical pocketing and allow full freedom of movement

  • Secure, secret storage of documents and essentials without altering the garment’s fit from three discreet pockets with hidden pocket within.

Parameta® A fabrics are rapid evaporation fabrics that help to keep you cool and protect you in warm environments.

How will my Páramo warm weather wear outperform other trek and travel wear?

The Parameta A fabric used for Páramo trek and travel wear provides superior performance for warm weather. As well as feeling light and cool, it is designed to actively cool you by spreading perspiration to prevent pooling and using every last drop of perspiration to cool you. The dense weave not only blocks virtually all harmful UV rays but also very effectively deters biting insects. Many other ‘insect deterrent’ fabrics use a treatment which will wash out after only a few uses. It dries very rapidly making it ideal for travel and expeditions when washing facilities may be limited.

In what kind of weather conditions can I use my Katmai Light Shirt?

The Katmai Light Parameta A fabric is ultra-cooling, holding perspiration close to your skin and evaporating it to keep you cool. It provides UV protection so is ideal for warm, sunny weather. Because the fabric provides active cooling, the shirt may be less comfortable in cooler, windier conditions, especially if you get wet. In more temperate conditions, we suggest a wicking baselayer in Parameta T+ or Parameta G, if necessary worn under a Nikwax Windproof, to provide less cooling.

Which garments should I use with my Parameta® A garment to get optimum performance?

Parameta A is an active cooling fabric, very effective in hot conditions, and so is often worn alone. If extra protection is wanted in windy or showery conditions it can be combined with a Nikwax Cotton+ outer or a Nikwax Windproof. Both of these will help to deflect wind and showers without inhibiting breathability or adding significant insulation.

In hot conditions, we recommend pairing Parameta A® shirts with a pair of light, fast-drying Parameta A® Cotton+ Trousers.


How do I look after this Páramo item?

This item works best if washed using one of Nikwax’s synthetic baselayer products such as BaseWash® or BaseFresh®. Unlike standard washing detergents, these products enhance the wicking performance of your kit and prevent odour build up.
