The solution for eliminating body odour could lie in a secret ingredient used during the World War II period.
As a key component of gas masks, it has taken on some of the most toxic substances known to man.
Brit inventor Steve Rawlings and his son have turned a gas-absorbent material created for Second World War gas masks and used in chemical warfare suits into an anti-BO clothing patch.
The tea bag-sized Odegon patches 'eliminate, harness and store' the molecules responsible for the unpleasant smell of sweat.
The patches last as long as the garment. One can iron them on or sew them in and then forget about them.
"I thought that if it can stop sarin and mustard gas and all those other terrible gases, surely it can stop body odour.
"I assumed that if the material met chemical, biological, radiological and nuclear suit requirements, it would easily tackle BO," the Daily Mail quoted Rawling as saying.
Its composition, however, is a closely guarded secret.
All-day travellers or people with skin sensitive to deodorants and antiperspirants will find them especially helpful.
The tags, however, don't absorb the liquid component of sweat.
The patches can also be tricky to remove from the inside of garments, and so those who just want to experiment with them should attach them through sewing rather than ironing.
