A multifunctional mid-layer, thanks to the combination of POLARTEC POWER GRID in the core part of the garment, and SKIN-LIFE and DRYARN fibres with SEAMLESS technology on the sides. This ensures excellent thermal insulation properties, which combined with the high elasticity of the side insets, add up to a especially functional snug fit. Body heat is kept inside the garment, while perspiration is free to escape through the POLARTEC grid structure, ensuring a pleasant feeling of warmth and dryness. Experimentation through the combination of different structures, has led us to the creation of a mid-layer that is unique of its kind. The thermal nature of a second layer, as well as the comfort of an undergarment, make ARIES the base product for your technical clothing.
