An insight into Cool‑Lite™ via Icebreaker’s own Jen Irick.

Jen Irick holds the position of Global Head of Product Marketing at Icebreaker, working between New Zealand and the US. Her role sees her work in collaboration with the New Zealand-based Brand team the Product Team based in Portland, Oregon, “setting the global vision for product marketing and executing the Icebreaker brand’s strategic direction”.

Although she has only been working at Icebreaker for less than six months, “I’ve been wearing Icebreaker for over ten years,” she says, making her the perfect person to grill about the company’s incredible new Cool‑Lite™ fabric technology.

What can you say about Icebreaker Cool‑Lite™?

Cool‑Lite™ is a blend of Merino and TENCEL®, and the aforementioned two main “summery benefits” of Cool‑Lite™ are moisture management and odour-resistance. Merino alone is an amazingly versatile fibre that is naturally moisture wicking. This means that in addition to keeping you warm when it’s cold outside, it also keeps you cool when it’s warm outside. TENCEL® is a natural fibre that has similar moisture wicking properties to Merino and is fast drying, so the two fibres combined create an exceptional temperature regulating fabric that keeps you cool during physical exertion and in warm climates.

Cool‑Lite™ is naturally odour resistant because Merino and TENCEL® fibre surface characteristics make it a hard place for bacteria to bond. Bacteria needs warm, moist environments to breed, so the anti bacterial fibre surface coupled with the wicking properties of both fibres makes Cool‑Lite™ a naturally odour resistant fabric.

How long did it take to develop the Cool‑Lite™ blend? Was it developed in house, or by a company on behalf of Icebreaker?

A company called Lenzing started to develop TENCEL® Merino blends about eight years ago. Icebreaker partnered with Lenzing with the aim of creating a specific blend aimed at the outdoor market. We worked together to create the blend that became the Icebreaker brand name Cool‑Lite™.

So Cool‑Lite™ is a clever blend of Merino and a very technical fibre. How would you describe what TENCEL® is exactly?

TENCEL® is an amazing lyocell fibre of botanic origin. It is the strongest cellulose fibre and is naturally derived and made from the wood pulp of eucalyptus trees.

Why is it considered sustainable?

The eucalyptus trees from which TENCEL® is made are harvested from sustainable tree plantations. The raw materials come from managed forests that are independently certified by the Soil Association on behalf of the Forest Stewardship Council. The production process was designed with the environment in mind and has won numerous awards including the ‘European Award for the Environment’ from the European Union.

What does Cool‑lite™ feel like on the skin?

Cool‑Lite™ has a silky softness that feels amazing next to skin. The TENCEL® fibre in Cool‑Lite™ is a round cross-section with a smooth surface, so when combined with Merino creates an incredibly comfortable, soft fabric with beautiful drape.

What kind of products have been created by Icebreaker using Cool‑lite™?

Cool‑Lite™ is so versatile that it is used in a variety of styles. It is used in knits and wovens, and in everything from tops, and bottoms, to accessories. It's moisture management properties make it a great fabric for active, training, and adventure styles, whilst its soft hand-feel and drape make it a great fabric for lifestyle pieces.

Who would benefit most from Cool‑lite™ products?

Clothing made from Cool‑Lite™ is especially attractive to people who are looking for high performance, natural alternatives to synthetic fabrics and to those of us who care about the impact that our clothing has on the environment. Cool‑Lite™ is also ideal for people who travel. Especially adventure travel. It is lightweight so packs well, and it doesn’t stink so you can wear something multiple times without the need for constant washing. This means the amount of clothing you have to pack when you travel is dramatically reduced. And when your gear does get ripe and needs a wash, Cool‑Lite™ is fast drying so you don’t have to worry about packing or wearing damp gear.

What are your favourite Cool‑lite™ products, and why?

I travel quite a bit for both business and adventure. My worst fear is the possibility of lost checked luggage so I have become an expert at the art of packing for weeks in a carry-on bag. I just got back from 10 days in New Zealand and pretty much lived in Cool‑Lite™ while I was there. I especially love the Sphere Short Sleeve and Long Sleeve Crewe shirts. They are great summer basics and ideal for layering. My new favourite is the women’s Cool‑Lite™ Mira Pant. It was summer when I left New Zealand and winter when I arrived back in Portland, and the Mira Pants did me right in both climates and were super comfortable on the long plane ride home.
