Got a new winter suit, ultra-stretchy, nice and snug around the wrists and ankles , not quite so snug elsewhere eg neck. Found that if & when water gets in it can't get out again and stretchy suit expands round middle and thighs so I end up sloshing about in a sack of water. Big problem if I need to add to that ....(don't laugh) Suit clings tight to legs below knees and I can't really drain it until I'm out. Works great in all other respects. Didn't have this problem with previous suits as they flushed more readily and forced the water through. (Plus oldest one is less stretchy so just doesn't allow that much water in.) Any advice on best site and method for creating drainage holes?
