Product test
We've tested the material in a climate-controlled room in order to determine its performance level. The results have proved the thermo-regulating properties of the wool. After exercise and heavy sweating, the wool is able to maintain body temperature while a synthetic material lowers the temperature again more quickly. The Merino wool therefore limits the unpleasant effect of chilling or the “freezing effect”.

Maintenance tips
Wash at 30°C on a wool cycle. Dry flat.

This product is extremely soft and ultra-light. One of the must-have apparel if you are planning to spend time in the mountains. Please provide more colours. so that I can buy the same again.
Quality Product!

Trids this out as a baselayer in EBC trek..this is a valur for money product..
Great price
Used for More than 1 year
Someone (Mico 1st comment?) commented that it was too thin! CRAZY comment! This is an undergarment, a thermal. You will NOT get a better price for Merino. Loads of "Merino" technical clothing out there but its 10-25% merino mixed with synthetic. 100% Merino will cost you £60-£90 elsewhere. I've never found it cheaper than here. I did several successful trips on this including the famous "Umbwe" route on Kili. Totally recommend. Leggings also great.

I enjoy trekking in this
Used for 1 week or less
These are a bit thin despite being 190g. Wouldn't recommend for the price - would buy if about £20. Sent it back, would pay a little bit more and get a decent one (North Ridge at Go-Outdoors are far better)
Fluctuating price
Used for More than 1 year
Extremely comfortable
Nice fit
Half zip feature is very good while trekking
Sleeves could be just a little longer

Very disappointed that the price has been increased by Rs. 500, dissuaded me from buying another, quite shocked.
Good weight and insulation
Used for 2 to 8 weeks
Just what I needed for an ultra marathon. Fits in my pack, meet the kit list requirement and is a warm layer if required.
Comfortable - love this
Used for 2 to 8 weeks
I wore this for the Routeburn Track and absolutely love it. Very comfortable against the skin. Warm enough and did not get hot or sweaty for the uphill bits. The neck is good as it has a bit of height to avoid the draughts and the zip is great when you are exerting yourself. Has washed up well so far and the price is a steal when you compare it to overpriced NZ brand merino garments.
