Love the Horizontal fly.Have been a Hom wearer for over 20 years now. First pair I picked out from an Hom shop made my gf blush so I had to buy them, despite being £35.They're well made, fit me great, even when I went up a waste size (damn you middle age spread!) and you don't have to buy the fancy colours if you don't want.Bought this size large - fits well and holds everything in place! Try this horizontal opening; you won't be disappointed.They could have been more comfortableNot what I had expected, too largeGood quality
