Icebreaker Cool-Lite Sphere Short Sleeve Crewe

Written by

Icebreaker Cool-Lite Sphere Short Sleeve Crewe tested and reviewed

Stay cool and dry all summer with the Sphere Short Sleeve Crewe. Combining 65% merino with 20% plant-based TENCEL® and 15% Nylon Cool-Lite™ is Icebreaker's lightest, most breathable fabric. Cooler and faster drying than pure merino, Cool-Lite™ still retains Icebreaker's signature odor resistance and soft feel. We use a heathered version, with casual set in sleeves and understated tonal logo to create Sphere, the summer shirt that's equally at home on a long hot climb as it is on a really slow, deserted beach.

Fabrics are continuously evolving, from the way they are merged together to the way they are designed to compliment other fabrics. It’s all about the hybrid and I can’t get enough of seeing the new versions develop from season to season. Admittedly some don’t work but when they do it is a breath of fresh air.


Fresh air links me nicely into this baselayer, at its core it’s Merino, known for its reluctance to stink! Icebreaker is known for its premium Merino so when they start to mix it up with other fabrics, you tend to have a confidence they know what they are doing. TENCEL is a new one for me but that just gives me the excuse to look into it, the fibres are made from wood, eucalyptus wood in this case. It’s stated that it is softer than silk. Well, mixed with the Merino and a touch of Nylon the Sphere is very soft indeed.

And light, the t-shirt weighs nothing it seems. The Sphere has a basic design, it’s simple and it works. I have worn it in 30 degree high humidity, under a hardshell for 12 hours and on the climbing wall for a couple of hours of extreme sweating to name a few occasions of use. In all its outings the top has been probably one of the most comfortable tops I’ve worn.

When a pack is pressed up against it does inevitably hold a bit of moisture being Merino, however, it evaporates quickly when even the smallest amount of fresh air gets to it.


The medium felt like quite a neat fit and with Icebreaker stating it’s a relaxed fit I would consider the sizing when purchasing. Personally I quite like the fit.


My Thoughts…

This is a simple looking top that contains a mix of fabrics to make something that simply just works. It’s comfortable, light and can be used in various levels of activity from knocking around the park to long days on the hill. It definitely lives up to its Cool-Lite title. I will still use the Sphere going into autumn and early winter as I run hot so there’s plenty of scope for use out with the summer.
