  • What is the Hydrostatic head of the shelter?

    Hello, 

    Thanks for the question. The OR Helium Bivy uses PERTEX Shield+ 2.5L fabric which has a 20,000mm waterhead rating and breathability rating of 20,000 g/m²/24hr . 
    I hope that helps but if you need anything further please don't hesitate to get in touch direct at web@mountainequipment.com and I'll do my best. 

    Kind Regards,

    Matt Eaton
