Headphones lol
2 way zipper even though the jacket is not reversible. Don't know why.
Has an inner layer to seal out cold
And a weather strip behind zipper. ( not sure what it's called.)
Over all it's a great jacket, very confy and warm even while turned off.
Sizing is spot on, great fit.
Nc weather is crazy I haven't been able to try it out alot since it's been mid 70's this week.
I will update my review when I really try it out in the cold.
I do wish it had more heat pads.
