Weight
Measures how heavy the garment feels in use. A lower rating balances weight with added warmth or durability, while the highest rating means ultra-light construction for ease of movement.
Breathability
Shows how well heat and moisture escape through the fabric. At the low end, garments are suited for light activity, while the highest rating ensures maximum airflow during intense exertion.
Pack Size
Indicates how compact the garment becomes when stowed. A lower rating offers moderate packability, while the highest rating means it compresses small for easy storage in a pack.
Durability
Reflects resistance to wear and abrasion. Lower scores are for lighter use, while the highest rating means reinforced fabrics built to endure demanding, repeated exposure to the elements.
Windproof
Shows how well the garment blocks air penetration. Lower ratings protect against breezes, while the highest rating delivers complete protection in strong, sustained winds.
Waterproof
Represents protection against rain and moisture. A lower rating resists light showers, while the highest ensures full defence in prolonged, heavy downpours.
Insulation
Measures how well the garment retains body heat. Lower ratings provide light warmth for mild conditions, while the highest rating ensures maximum heat retention in cold and harsh environments.
