If you could specifiy what conditions you are likely to encounter e.g. Temperature and Wind speed, this would make a recommendation a lot easier.
Last year the temp here got as low as 6 degrees F. Don't know about wind speed, but if I can tuck away in the woods, that will break a lot of wind.
Here's a pic from last winter. No, that is not running water coming out of the garden hose. It is solid ice.
