Aircraft
Aircraft X had a write-up for smoke/fumes in the past week. On date; it had an eval flight and was signed off. Upon takeoff; an odor began emitting that smelled like a wet rag/skunk. I noticed right on the climb out and it became increasingly worse. The FO (First Officer) did not notice anything except right after take-off. After reaching a safe altitude I asked the FA (Flight Attendant) if she smelled something as well; she replied positively. I told her we would be returning to the field immediately and then the FO and I then advised ATC. We smelled the fumes mostly throughout the entire duration and faintly after landing. We taxied back to the gate with emergency equipment following us.Captain and FA; FO only smelled an odor on takeoff.Fumes/odor.Precautionary Air Return landing. Tried using 02 masks but mine was giving me a bad feedback through the headset. FO's mask had a boom issue and could not communicate at all. We decided then not to use the masks.Find what is causing these issues.
We taxied to runway and began our takeoff roll. After taking off the Captain asked me if I smelled anything. I told him not really. I believe I said I can smell the packs; not smoke or anything. He stated he smelled something; fumes; not smoke or electrical. He asked me to call the FA (Flight Attendant) and ask her. I called our FA and she stated she could smell something but not smoke. The Captain told me to advise ATC and ask to return to the field. The only smells I could smell were normal smells associated with a take off in our aircraft. ATC stopped our climb and cleared us vectors. I programmed the FMS; radios; and landing speeds. I told the Captain we would be landing overweight. He stated he understood and proceeded to land. We were met by fire rescue and followed to the gate. The Captain smelled what he described as 'musty' or 'wet socks'.
