FORCLAZ products undergo rigorous tests at our design centre at the foot of Mont-Blanc, before being tested in the field in real conditions.
Odour control lab tests
Made from 86% Merino wool, the fabric limits perspiration odours and has been laboratory tested according to ISO 17299-3. This means you can wear your top for longer, and carry less clothing on multi-day treks.
Thermal lab tests
We've tested the material in a climate-controlled chamber in order to determine its performance level. The results highlighted the heat-regulation properties of wool. After intense physical exercise and increased perspiration, wool helps to maintain a consistent body temperature while synthetic fabrics cool down faster. The unpleasant cooling or "freezing effect" is therefore reduced by the Merino wool.
Field tests in the mountains
In November 2018, 8 trekkers (4 men and 4 women) and part of the Forclaz design team tested this long-sleeved t-shirt for four days in the Southern French Alps (Lus La Croix Haute). There was wind, rain, and even a bit of snow, allowing them to really put the t-shirt to the test. They were then able to make a few final tweaks to the design, before validating it for mountain trekking use.
