Are you thinking water resistant tear off sweats? I have them on special at www.funkystitches.com I can get great rain jackets but for genuine rain pants, for kids its a tough one. Contact me, I can see what I can find.
Thanks! Cabela's has what I was looking for. I didn't want to spend a lot for his pair. I'll probably have them embroidered as he is notorious for leaving/loosing clothes.
