I got a killer pink hi-vis tabard from HOYS last year. Can't remember the make and no, you can't have it! I'll read the label next time I'm up at the yard and pm you if its still legible. Have you tried good old google?
Dont know about pink, but I got one of the Robinsons riding jackets in hi viz yellow a couple of years ago, they are about £25 for kids and £30 for adult sizes. It is waterproof and soooo cozy, with all the usual riding coat features - the zip has only just broken - I am about to buy another 2 so that daughter and I dont have to fight over it - if ythey dont do a pink one perhaps you should write and suggest it!
