Life
Fibres people keep and wear longer score higher.
70 + Life + Breathes − Pills − Wear = Score
Every score starts at 70, the cotton benchmark used in European durability rules.
Breathes
Fabric that takes up moisture feels cooler on skin.
Pills
Strong synthetics hold onto pills, so they look worn sooner.
Wear
Some fibres wear through faster than cotton.

89Seam proof
90+Heirloom
A tag shows the fibre, not the sewing. Show us more and the score can go higher.
We never score the brand or the price.
