The P&G brand has enlisted the help of marathon runner Paula Radcliffe to promote the limited edition nappy, created especially for the summer games.
The product, retailing at around £6.49 for a carry pack, features a red polka-dot Union flag and blue and white detailing - with GB printed on the back.
Paula, a mother-of-two, posed up with her 16-month-old son Raphael for a photoshoot unveiling the GB Design Active Fit nappy, allowing mums and babies to 'show their national pride.'
The mother-of-two, 38, says: 'As an Olympic Games athlete I know how effort and determination can help us reach our full potential.
'As a mum I see the same determination in my children as they learn to overcome every day challenges through play.
'I understand the importance of having the right kit to help me achieve my athletic potential.'
