Hey, I work for EE, but I’ll put my two cents in for your questions.
To start with, yep, definitely hoodless, but depending on how you sleep that might be a positive. Side and stomach sleepers often get frustrated with mummy bag hoods, as they can end up being more in the way than anything, though for some it doesn’t bother them. With our quilts and the Convert, it’s designed to go with a warm hat, a balaclava, or our Hoodlum. If you like sleeping with a puffy jacket on, some will also just use their jacket hood.
As for the zipper, it’s a really small, lightweight zipper (much smaller than you’re used to with most sleeping bags), so assuming you’re on a pad it’s not really that noticeable when you’re using it as a quilt. Then obviously in sleeping bag mode the zipper is up your chest, so no issues there.
