It does zip in, in front.Their are elastic & velcro loops at the ends of sleeves, legs and neck to hold the liner in if you want. I may use them but haven't yet. I just keep them separate and put on the liner when needed. The liner and shell have separate (independent) front zippers and full length leg zips. I actually wore the liner alone with an insulated vest for a day outside in the 40's walking around and was comfortable.
