Police have released two further images in the hope they will assist detectives in identifying the man who washed up on Perranporth Beach.
The black and white woolly hat and green/blue rucksack, which has dark green webbing and a black panel on the back, were both found on Perranporth Beach on the same day as the body (Tuesday, February 25).
It is not known whether they belong to the man or if someone visiting the beach has lost them.
The discovery of the body of a man on Perranporth beach is now being treated as 'suspicious', following the results of a forensic post-mortem examination.
The post mortem was conducted on Friday (February 28), and according to police, "multiple injuries were found on the body which are inconsistent with drowning and cannot be easily explained".
Police believe the man was in the water for no more than 24 hours.
Anyone who has any information about the items is asked to call police on 101 quoting log 381 of 1 March.
