Motorcycle rain gear

This falls into the "improvement" category, like the Union Suit post... Motorcycle rain gear - I've had several different suits now, and guess where they all leak most annoyingly noticeably? IN THE CROTCH! So let's fix this matter. First of all, standard design has several potentially leaky seams coming together IN THE CROTCH. Get that outta there. I believe the design is called a gusset crotch? - where rather than having the leg seams meet at the crotch, a separate patch of material is used in that area - increasing mobility and decreasing the risk of leakage. I know it's a tough nut to crack - you've got water being forced by strong wind - potentially 100mph, and the wind is pushing that water up the leg seams into the crotch area. So? Design the seams so the water is diverted from that area, not funneled into it?!
