The only rucksack I knew was called Kelvin......
An absolute zero carried by everyone.
Are these unisex shoulder bags some warry thing? Or intended to replace brief cases, nav bags etc?
'Thrombo' (as in 'wandering clot'), an unlamented previous Stn Cdr at the Covert Oxonian Aerodrome, was concerned that high-visibility cyclists' bags were 'unmilitary' FFS! Never mind being safer, they weren't NATO green or RAF blue - so were Something To Be Concerned About. True prattishness of an impressive calibre!
