Merino Thermal Base Layer

POLYGIENE® and merino blend

At CIMALP®, we have developed a 200g/m² double-sided weave: 80% POLYGIENE® polyester and 20% merino blend.

Result: tried, tested and approved! Even with sensitive skin and/or a wool allergy, no signs of itching. With the thermal properties of the best merino blends, there is zero odour after exercise.

The difference in the details: No odour even after 100 washes. 1/2 zip with YKK stops. Thumb loops. For the specialists...SMART DRY FIBERS and a double layer for optimal moisture wicking.


Sweat is natural and doesn’t smell. However, when you add fabrics to the mix, this creates a warm and humid environment which is an ideal breeding ground for the bacteria that cause bad odours. It is the odour emitted by these bacteria that leads to discomfort and itching. IONIC® SILVER by POLYGIENE® prevents the growth of bacteria and mould at source. Permanently.

To achieve this, POLYGIENE® uses a very low dose of silver salt (silver chloride), naturally present in water and soil, for its antimicrobial properties. This technology is integrated into the fabric and is not eliminated with washing, meaning that these odours are always kept under control.


- Ergonomic thumb loops
- YKK zip closure
