Frequently Asked Questions

Evaporative Cooling Products

Is HyperKewl™ fabric safe?

Yes. It contains non-toxic polymer fibres.

How does it work?

Our HyperKewl™ is sewn into the lining of all our garments. The special fabric absorbs water very quickly and releases it very slowly for extended cooling from evaporation.

How long do I hydrate the garments?

1-2 minutes.

What is the lifespan of the HyperKewl™ Fabric?

HyperKewl™ fabric is designed to provide up to 100 wet/dry cycles. Water absorbency will diminish over time as HyperKewl™ fibres migrate and entangle within the fabric structure. You may see an initial decline in the absorption of water after 5-10 wet/dry cycles as the fabric “settles”, but absorbency will remain relatively stable after this initial 5-10 wet/dry cycles. This is normal and the fabric is still very effective at water absorption and evaporation. Absorbency will also be impacted by hydration length, garment care, water quality, as well as other factors.

Can the products be reused?

Yes. Just make sure you hang them to dry when not in use.

How much will the items weigh?

You control the weight of your garment by how long you hydrate it. Our #6529 Sport Cooling Vest soaked for about 2 minutes will weigh approximately 750 grams.

Can I silk screen and/or embroider the products?

We recommend embroidery.

How can I wash the garments?

In order to maintain the longest life of the product and HyperKewl™ fabric it is best to hand wash the garments with a brush and light soap and water. Avoid soaking the garments in soapy water. Simply use the brush to wash off the garment.

Phase Change Cooling products

What temperature is the Phase Change Material (PCM)?

A comfortable 14 degrees C.

How do you activate Phase Change Material?

Solidify the inserts by placing them in a fridge, freezer, or ice water.

How long does it take to activate them?

Approximately 30 minutes.

How much does PCM weigh?

PCM is 25% lighter than water.

Is PCM safe?

Yes, it is non-toxic, non-carcinogenic, and non-flammable.

Is PCM reusable?

Yes, the inserts can be re-activated over and over again.

How long will the PCM stay activated?

Vest inserts will remain at 14 degrees C for up to 3 hours.

Air-Activated Heating products

How do HeatPax Warmers work?

The Warmers are filled with iron powder which oxidizes when exposed to oxygen. This is a powerful exothermic reaction resulting in heat.

How long do the HeatPax Warmers last?

Body Warmers 20 plus hours, Mini/Hand Warmers 8 hours, Adhesive Toe Warmers 5 hours.

Can the Warmers be reused?

You can stop the HeatPax at any time and reuse them at a later date by sealing them off from the oxygen in the air (i.e. plastic container or airtight bag). They are discarded when completely consumed.

How do I get the HeatPax Warmers to heat up?

Simply tear open the package. Wait 10 minutes for them to heat up fully.

Are HeatPax Warmers safe?

Yes, they are non-toxic.

How do I use them to stay warm?

After opening them, place the Warmers in your garment or pocket for maximum comfort.
