• £15 for a jacket with that kind of fabric is very good value:
    Water Resistance Rating: 10,000mmH2O Breathability Rating: 8,000g/sqm/24 hrs

    E-vent figures:
    Water resistance rating 30,000mm hydrostatic head with a minimum MVTR of 21,000g/m2/24hrs
    the reinforced thicker bits on my montane jacket:
    Water resistance rating 30,000mm hydrostatic head with a minimum MVTR of 15,000g/m2/24hrs

    the hydrostatic head is the vertical column of water it would take to permeate the fabric (i.e 30m)
