two relevant things about night-time headwear for quilt users:
- try to re-use what you already have anyway.
- be able to create a non-interrupted layer of insulation around head and neck, like a balaclava does, with the option of covering mouth and nose too.
A balaclava is perfect but no so versatile during the day. For not too cold temps, I usually take a fleece cap and a buff. For colder weather, I add a powerstretch balaclava or, colder yet, a polarguard or down one.
