Whats a minimal hydrostatic head

Re: Whats a minimal hydrostatic head
Thanks Colin... I think the article would suggest that my option of 8000 wouldnt reallly be suitable for an extended downpour I'm seeking something to handle driving rain for extwnded periods
My Lowe Alpine jacket the other day felt a bit 'boil in the bag' and possibly time to move it on soon in case anyone has any bright ideas to give it a new lease of life
My first and goto option would be (obviously) the BB staple Columbia Outdry but expensive at the mo...

Re: Whats a minimal hydrostatic head
1500 as a minimum for a material to be considered 'waterproof'.

Re: Whats a minimal hydrostatic head
I swear the marmot rep of many moons ago told me it should be about 10k in the ‘real world’, 10K would be on for sitting in a puddle and staying dry.
The minimum uk standard changes depending upon the season, think it was 1.5k for summer and 3 for winter.

Re: Whats a minimal hydrostatic head
Maybe higher density in winter so particles more tightly packed and don't 'fluid' through the pores of the material?Bearbonesnorm wrote: ↑Mon Jul 22, 2019 5:58 pmOdd, is water somehow wetter in winter?The minimum uk standard changes depending upon the season, think it was 1.5k for summer and 3 for winter

Re: Whats a minimal hydrostatic head
Wouldn't that then mean that you'd need a lower HH in winter.Maybe higher density in winter so particles more tightly packed and don't 'fluid' through the pores of the material?

Summer rain is that fine, misty stuff falling from the sky.
Winter rain is heavy, wet stuff driven by gale force winds.

Re: Whats a minimal hydrostatic head
More rain in the winter, I dunno why
Quick google search and it’s looks like the MOD set their target at 800mm
Can’t find anything via the government website on minimal standards, just blogs after blogs giving different results

Re: Whats a minimal hydrostatic head
In reality it’s all academic anyway.
If you ride for more than a few hours in proper rain you will get wet.
Water will hose in through all the holes your head arms and body stick out through.
You will sweat yourself wet.
Water will seep in through all the little thorn holes and scuffs.
If it has put zips or other ventilation water will come through there as well.
Be prepared to get wet!
