Have noticed the same problem with the zipper...will not stay sipped when pulled all the way up....not so good on really cold/windy days. However, that is my only complaint about this jacket. I've worn it on single digit (F) days and was really impressed at how warm it is. Keeps you dry in light to moderate snowfall.... worth the money.
