What is the Hydrostatic head of the shelter?
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 email@example.com and I'll do my best.
Hi, I’m just checking if this is the latest update of the bivy? Or the previous version? Thanks!
Thanks so much for your question. These are the latest model of the Outdoor Research Helium Bivy and fresh out of the factory. Sorry I did have the weight and a couple photos listed that were of the previous iteration but I have updated those now. I hope that helps but if you need any further assistance please don't hesitate to contact us by phone (02 9264 5888) or email (firstname.lastname@example.org) and we'll help out.
