Hi all,
There's a post attributed to Polartech that says 5,000 MM is not waterproof but 'pretty resistant'. It was comparing Power Shield Pro (5,000mm HH) to Neoshell (10,000 mm HH)
http://forum.kuiu.com/viewtopic.php?f=2&t=585Yet, on Polartech's own site it says Neoshell's HH drops to 5,000 MM after 20 washes. Which going by what's said by Polartec in the link above, would make Neoshell less than fully waterproof after 20 washes.
So which is which? Does anyone know?
Quote below taken from link above:
"Polartec NeoShell is waterproof to 10,000mm - that's 10 meters of water pressure - we have been testing this fabric in the field for the past 2 years and are very confident in its ability to keep you dry. While many other waterproof fabrics go to 20,000mm of water resistance, we believe this is overkill and in fact becomes a liability because you directly trade off breathability.
Polartec NeoShell has an excellent DWR (keeps the surface fabric from wetting out) and the membrane allows a tiny amount of air to flow through the fabric (0.5 CFM). Other waterproof technologies require heat and pressure inside the jacket (that clammy feeling of traditional shells) while Polartec NeoShell does not require this pressure - even a small amount of airflow through the fabric massively accelerates moisture vapor transport away from your body. It's not so much air flow that you get wind chilled - but enough to keep you feeling much drier inside the jacket than full film shells.
As a bow hunter myself (Colorado - elk), I'm very anxious to have some Polartec NeoShell produced in camo.
Hunters should also take a look at Polartec Power Shield Pro - this utilizes the same membrane technology as Polartec NeoShell but offers
5000mm of water resistance (not waterproof but pretty resistant), a great DWR and 2 CFM of airflow. This is the ultimate softshell technology...again, hoping to see this in camo sometime soon."
