Hey! I've just bought my first pair of wicking knickers!
In M&S, all the men's 'ViewFrom' gear is in the same place but rather annoyingly they've split up the girls' stuff over two floors and in 3 locations; hence I didn't know that they did any wicking undies there. I was pottering round the sale yesterday and Bob spotted a ViewFrom stall with 'activedry' undies on, all reduced.
They had thongs; tight, silky little shorts; and bras; in lilac and black and in nearly all sizes. I got some shorts for £7 reduced from £10 with a nice meshy bit in the lumbar area and no side seams, and a bra for £9 which was £20.
No wind-proof front panel, but I'm assured that only men need those LOL
