Got some huggalugs for £6.99 incl post, I googled huggalugs free postage.
They are great black with skulls - got a bit fed up with girly after 4 girls!! So yes they do boy's designs. They are really good quality.
Did find another place that was doing 4 for the price of three too, although postage for the four was about £4 which only makes them a teeny bit cheaper and you have to commit to 4 pairs at once.
I find them, like pp have saiid, great when babywearing and also they are good for nappy off time.
I will be buying more.
