I've ordered stuff from GroundEffect, the NZ mail order place and they were superb...one week to arrive 12,000 miles and half the price of UK stuff, incl. postage :)
the first is a top the second is specs, I don't know about them but have to agree about Ground effect, they are fantastic, had lots of other products from them and they have all been wonderful, I doubt that they do make a bad product.
Ground Effect are good, quick and cheap, but their sizing is off beam. The medium (39" -43") is more like 44" chest. Get a size smaller than you think you need.
Ground effect is top gear, double happies are exelent baggy shorts and flash gorden is a good windproof/showerproof top. Postage is 2 (yes two - 5 days) aprox 2/3 the price of the same gear over here. Buy some now!!!
