Assesses the effectiveness of the barrier against rain and moisture. The grading (1 to 5) measures the actual level of protection: a Grade 1 can be found, for example, in basic fabrics with high permeability, while a Grade 5 indicates total impermeability, a result that can be achieved by using solutions such as three-layer (3L) membranes combined with fully taped seams or equivalent technologies.

It measures the ability to dissipate water vapor and body heat. The system grades performance: a Grade 1 provides basic breathability, appropriate for protective materials for normal urban use, while a Grade 5 ensures maximum vapor escape during intense exertion, achievable, for example, with high-performance membranes (e.g., >20,000g/m²) or special active fabrics.

It measures the ability to block cold air flows. The score reflects the degree of shielding: a Grade 1 provides maximum ventilation (a typical feature, for example, of "Air Permeable" structures), up to a Grade 5 for absolute insulation against gusts, which can be achieved through "Total Block" membranes or very high-density weave fabrics.

It analyzes the specific weight and packability of the garment. Grading defines practicality of transport and packability: a Grade 1 is generally assigned to outerwear that emphasizes weight and structure, while a Grade 5 indicates maximum agility, typical (but not exclusive) of "Ultralight" garments, designed with minimalist designs and easily foldable materials.

It indicates the level of body temperature maintenance and thermal insulation. The scale rates the intensity of protection: a Grade 1 indicates light insulation, often characterized by the absence of padding or thin linings, while a Grade 5 certifies extreme warmth, which can be provided by materials such as goose down with 800+ Fill Power or ultra-high-weight synthetic insulation.
