Lobsters in the ocean are rival because not everyone can catch them at the same time, but they are not excludable because it is difficult to prevent someone from catching them. Cable TV is both rival and excludable because not everyone can watch the same channel at the same time and it requires a subscription fee. National defense is non rival and non-excludable because it is a public good that benefits everyone and cannot exclude people from receiving it. Clothing is rival and excludable because once someone owns a piece of clothing, someone else cannot wear it at the same time and the owner can prevent others from wearing it.
