I am not in the US but a local manufacturer does tyvek bivies as sleeping bag covers. Any interest in the community for a water resistant bivy for use under a tarp when all you might want is a little incidental spray protection and not a full on shelter? Lighter and more breathable.
32oz OR Alpine is not sub-12oz...
Good thing we have knowledgable staff looking at these polls instead of computers, so we can verify that a product fits the poll, and can read the discussion too. Thanks for flagging this one as it's easy to remove!
Cheers, Danny
@DannyMilks - back to true "Ultralight" roots?
That's the goal :) But the line between ultralight and light is usually a personal definition.
