Assigned a 5 day ZZZZ trip from reserve.  On the deadhead leg; I observed non-compliance with the mask policy from one of my fellow crewmembers; simply no face covering worn at any time during the flight despite clear policy and announcements from the FAs.  On the working legs; none of the 4 of us wore our masks once the door was closed until we arrived in ZZZZ.  All of us wore masks in ZZZZ airport; but that relaxed in the van and at the hotel.  On our return; 3 out of 4 of us wore masks through ZZZ.  The one who did not was stopped for 30 minutes by the CDC; but not given a reason.  As I walked through ZZZ1 after returning; I noticed less than half of uniformed pilots wearing a mask while more than 80% of customers did.  My concern is not with any one crewmember; but with two general principles: 1. intentional non-compliance with company policy.  2. reducing customers security both physically and psychologically.
Air carrier First Officer reported inconsistent use of masks per guidelines by crewmembers.
