The ring acts a bit like a vent on those nice
rain jackets with the ""pit zips"" allowing ventilation,
only it's around the neck letting heat escape.
Just remember it's around your neck or it
could cause all that water to rush in and
be downright fatal ! It's a bit of fatal catch 22.
Meant and designed for on-land gear gathering,
portaging, walking around, comfort during breaks, etc.
